General Trial InformationStudy Director: Owen/Lux/Franzenburg/Grossnickle


Trial Status: F one-year/finalInitiation Date: 4/22/2010

Trial LocationCity: Ames

State/Prov.: IAPostal Code: 50014

Country: USA

Objectives:The purpose of this study was to evaluate burndown and residual weed control programs

including Corvus, 2,4-D LV4, Roundup PowerMAX, Laudis, Cadet, Capreno, Ignite 280 and Sharpen in no-tillage corn production.

Conclusions:Treatments provided 99% giant foxtail, velvetleaf and common waterhemp burndown control

when observed on May 10, eighteen days after application. Common lambsquarters control with the treatments ranged from 92 to 99%. No corn injury from the treatments was observed at any time. Residual weed control with the treatments on May 19, twenty-seven days following application, was 90% or higher. Exceptions were Balance Flexx plus Capreno and Ignite 280 plus Sharpen which gave 83% and 55% giant foxtail control, respectively. Observations on June 10 and July 8, forty-nine and seventy-seven days after application, respectively, demonstrated a reduction in overall weed control from that noted earlier in the growing season. On July 8, control of giant foxtail ranged from 0 to 93%, velvetleaf 80 to 93%, common waterhemp 65 to 88%, and common lambsquarters from 82 to 99%. (Dept. of Agronomy, Iowa State University, Ames).

Iowa State University Early preplant applications of Valor SX, Fierce and Integrity followed by postemergence appliedRoundup PowerMAX in no-tillage corn production, Ames, IA, 2010.

Trial ID: ACN 2 Protocol ID: VUSA2010VALORMD68.01&02Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate early preplant applications of Valor SX,

Fierce and Integrity and preemergence applications of Lumax for crop phytotoxicity and early season weed control in no-tillage corn production.

Conclusions:Differences in corn stand were significant between several herbicide treatments. These

differences were attributed to variability in stand establishment and not herbicide treatment. All treatments exhibited excellent crop safety. Excellent giant foxtail, velvetleaf, common waterhemp and common lambsquarters control was observed with the treatments on May 28, twenty-five days after application, and ranged from 93 to 99%. The non-residual treatment of Roundup PowerMAX was an exception, where overall weed control ranged from 0 to 57%.

Roundup PowerMAX plus Valor SX plus Atrazine and Roundup PowerMAX plus Valor SX gave 85 and 75% giant foxtail control, respectively, when observed on June 7. Remaining residual treatments gave 91 to 96% control. Velvetleaf control on June 7 ranged from 55 to 92% with the residual treatments. Treatments of Roundup PowerMAX plus Fierce gave the highest velvetleaf control at 90 to 92%. Common waterhemp and common lambsquarters control on June 7 was generally good to excellent with the residual treatments and ranged from 88 to 99% control.

All treatments achieved 96 to 99% overall weed control when observed on June 29, twenty-two days following the postemergence (POST) treatments. On July 14, thirty-seven days after POST application timing, giant foxtail, velvetleaf, common waterhemp and common lambsquarters control with the residual treatments ranged from 83 to 93%, 67 to 85%, 88 to 99% and 80 to 99%, respectively.

Trial ID: ACC 1 Protocol ID: HSEC0014-2010USLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate crop phytotoxicity and weed control from

applications of Lumax, Lexar, Corvus, Atrazine, Integrity, Sharpen and Guardsman Max.

Conclusions:Significant differences were determined between several treatments for corn stand. These

differences were attributed to variability in stand establishment and not herbicide treatment. No corn injury from the treatments was noted on any observation date. Weed control was 99% overall with the treatments when observed on May 27, twenty-two days after application. On June 10, giant foxtail control remained good to excellent with the treatments and ranged from 92 to 98%. Velvetleaf control on June 10 was 63 to 95% with the treatments. Lumax, Lexar and Integrity provided amongst the highest velvetleaf control. Common waterhemp and common lambsquarters control with the treatments continued to be excellent at 99%.

Excellent giant foxtail control ranging from 92 to 96% continued to be provided by the treatments when observed on July 6 and September 15. Velvetleaf control on July 6 and September 15 was generally better overall than that observed on June 10 and ranged from 77 to 93%. On July 6 and September 15, treatments gave 87 to 99% common waterhemp and common lambsquarters control. Corn yields with the herbicide treatments ranged from 163 to 181 bu/A. No significant differences in yield between treatments were observed. All treatments gave significantly higher yields compared to the untreated control.

Iowa State University Two-pass weed management programs in corn. Preemergence applied Lumax, Lexar, Corvus,Atrazine, Balance Flexx, Integrity, SureStart and Bicep II Magnum. Postemergence appliedTouchdown Total, Durango DMA and Halex GT, Ames, IA, 2010.

Trial ID: ACC 2 Protocol ID: HBJU01A4-2010USLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate two-pass programs in corn for crop

phytotoxicity and weed control.

Conclusions:Differences in corn stand were significant between several treatments and the untreated

control. These differences were attributed to variability in stand establishment and not herbicide treatment. No corn injury from the preemergence (PRE) treatments was observed on June 4, zero days prior to the postemergence (POST) treatment application timing. Grass control ranged from 72 to 93% from the reduced rates of the preemergence (PRE) applied treatments on June 4. Woolly cupgrass followed by giant foxtail were the predominant grass species occurring in the study. PRE treatments, except SureStart and Bicep II Magnum, gave 93 to 95% velvetleaf control on June 4. Common waterhemp and common lambsquarters control on June 4 with the PRE treatments was 99%.

POST applied Halex GT resulted in negligible corn injury when observed on June 12, 18 and July 3. No other POST treatment caused corn injury when observed on these dates. On July 3, twenty-nine days after POST application timing, the PRE plus POST treatment grass control, ranged from 85 to 98%. Velvetleaf control on July 3 was 87% or higher with the Pre plus POST treatments. An exception was PRE Bicep II Magnum followed by POST Touchdown Total where 70% velvetleaf control was provided. PRE plus POST treatments gave 80 to 96% common waterhemp control on July 3, while giving 95 to 99% common lambsquarters control.

Late season observations of the weed control effectiveness of the PRE plus POST treatments were made on September 15. Grass control on this date ranged from 78 to 98%, velvetleaf 73 to 92%, common waterhemp and common lambsquarters 93 to 99%. The LSD for corn yield was high at 63.3 bushels and due in part to stand variability, sheet erosion and poor soil drainage. Corn yields with the herbicide treatments ranged from 141 to 177 bu/A. Most treatments yielded significantly higher than the untreated control. (Dept. of Agronomy, Iowa State University, Ames).

Objectives:The purpose of this study was to evaluate preemergence and/or postemergence

applications of Corvus, Atrazine, Balance Flexx, Capreno, Roundup PowerMAX, Laudis and Ignite 280 for crop phytotoxicity and weed control in corn.

Conclusions:Preemergence (PRE) treatments did not result in corn injury when observed on May 24,

twenty-one days after application. Early postemergence (EPOST) applied Corvus plus Atrazine and Balance Flexx plus Atrazine caused 5% corn injury on June 7, nine days after application. Mid-postemergence (MPOST) applied Capreno plus Roundup PowerMAX and Balance Flexx plus Capreno plus Roundup PowerMAX caused 8% corn injury when observed on June 14, seven days after application. Good to excellent weed control overall, ranging from 88 to 99%, was observed with the treatments and application timings on July 3 and 19, twenty-six and forty-two days after MPOST application timing, respectively.

Iowa State University Postemergence applications of Realm Q in corn, Ames, IA, 2010.

Trial ID: ACC 4 Protocol ID: USA-10-111Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate corn phytotoxicity and weed control in corn

from Realm Q used in two and one-pass programs.

Conclusions:Preemergence (PRE) and postemergence (POST) treatments demonstrated excellent crop safety

on all observation dates. On June 12, fifteen days following the POST applications, giant foxtail control ranged from 87 to 98% with the two and one-pass treatments. Velvetleaf, common waterhemp and common lambsquarters control was 99% on June 12. Two-pass PRE plus POST treatments gave 93 to 98% giant foxtail control when observed on July 23, fifty-six days after application. One-pass POST treatments gave 78 to 90% giant foxtail control on July 23. Both two and one-pass treatments gave 98 to 99% velvetleaf, common waterhemp and common lambsquarters control on July 23.

Iowa State University Two-pass weed management programs in corn. Preemergence applied Dual II Magnum, Bicep II Magnum,Lexar, Lumax, and Bicep Lite II Magnum and postemergence applied Halex GT, Roundup PowerMAXand Northstar, Ames, IA, 2010.

Trial ID: ACC 5 Protocol ID: HRDL04A4-2010USLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate various two-pass weed management programs in

corn for phytotoxicity, weed control and yield.

Conclusions:Differences in corn stand were significant between several treatments. These differences

were attributed to variability in corn stand establishment and not herbicide treatment. No corn injury was evident from any preemergence (PRE) applied treatment when observed on June 4, prior to the postemergence (POST) treatment timing. Giant foxtail control was generally good to excellent on June 4 with the reduced rates of the PRE applied treatments, ranging from 86 to 99%. On June 4, velvetleaf control was 96% with PRE applied Lexar and Lumax, while remaining treatments provided 8 to 75% control. PRE treatments gave 99% common waterhemp and common lambsquarters control on June 4.

Corn injury was observed from POST treatments on June 12, 19 and July 3, eight, fifteen, and twenty-nine days after application timing. Injury ranged from 0 to 10% across the three observation dates. Weed populations in the study were light and mid to late-season control observations following the POST treatments reflected this. Overall, weed control was good to excellent with the treatments on June 19, July 3 and August 11 and ranged from 93 to 99%. Corn yields with the herbicide treatments were low and ranged from 132 to 152 bu/A. Most treatments yielded significantly higher than the untreated control.

Trial ID: ACC 6 Protocol ID: BASF Kixor 11Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate the efficacy and tolerance of preemergence

applied Integrity, Lumax, Corvus, Sharpen, Harness Xtra, and SureStart in corn.

Conclusions:Significant differences were determined between several treatments for corn stand. These

differences were attributed to variability in stand establishment and not herbicide treatment. No corn injury was evident from any treatment on any observation date. On June 5, thirty-two days after the reduced rate preemergence (PRE) applied treatments, giant foxtail control ranged from 92 to 96%. Velvetleaf control ranged from 50 to 95% on June 5. PRE applied Harness Xtra and SureStart gave 50 and 57% control, respectively, while remaining PRE treatments gave 87% or higher velvetleaf control. Common waterhemp and common lambsquarters control was 99% with the PRE treatments.

Giant foxtail control on June 25 twenty days after the POST applied treatments followed PRE, was excellent and ranged from 93 to 98%. On June 25, velvetleaf control with PRE applied Harness Xtra, Sharpen plus Harness Xtra and SureStart all followed by POST Roundup PowerMAX, gave 50 to 75% velvetleaf control. Remaining PRE plus POST treatments gave 90 to 96% velvetleaf control. Common waterhemp and common lambsquarters control was 88 to 99% on June 25 with the treatments. On July 21, treatments generally gave similar giant foxtail, velvetleaf, common waterhemp and common lambsquarters control to that observed on June 25.

Iowa State University Cadet and Resource applied postemergence with Roundup PowerMAX in corn, Ames, IA, 2010.

Trial ID: ACC 7 Protocol ID: FMCLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate Cadet and Resource applied postemergence

with Roundup PowerMAX for crop phytotoxicity and weed control in corn.

Conclusions:Differences in corn stand between treatments were not significant. Early postemergence

(EPOST) treatments caused 0 to 17% corn injury when observed on May 29 and June 7, five and fourteen days after application, respectively. EPOST treatments gave 98 to 99% giant foxtail, velvetleaf, common waterhemp and common lambsquarters control on May 29. On June 7 and 15, fourteen and twenty-two days after EPOST application timing, 80 to 99% control of giant foxtail, common waterhemp and common lambsquarters was provided by the EPOST treatments. Velvetleaf control ranged from 13 to 57% with the EPOST treatments. Sequential postemergence (SPOST) treatments of Roundup PowerMAX improved overall weed control when observed June 21 and 29, six and fourteen days after application. Control of giant foxtail was 99%, velvetleaf 95 to 99%, common waterhemp 98 to 99% and common lambsquarters 94 to 99% was provided with the EPOST plus SPOST treatments on June 21 and 29.

Iowa State University Two and one-pass programs in corn. Harness Xtra, Harness, Integrity, MON 63410, SureStart,Halex GT and Roundup PowerMAX, Ames, IA, 2010.

Trial ID: ACC 8 Protocol ID: 2010-01-04-12Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The objective of this trial is two fold. One aspect is to compare crop safety with

MON 63410 compared to standards in a weed free environment (pre product used). The other is to evaluate efficacy of potential tank mix partners with MON 63410 compared to standards in a one pass POST system.

Conclusions:No corn injury was observed on May 29 from the preemergence (PRE) applied treatments.

Giant foxtail, common waterhemp and common lambsquarters control with the PRE treatments was 95% or higher on May 29. PRE applied Harness Xtra gave 68 to 82%, Integrity gave 98%, Harness plus Hornet WDG gave 53% and Harness gave 7% velvetleaf control on May 29.

Early postemergence (EPOST) applied treatments resulted in 0 to 15% corn injury on June 5, seven days after application. Injury symptoms occurred primarily as leaf chlorosis. Mid-postemergence (MPOST) applied treatments resulted in 2 to 5% chlorosis when observed on June 21, six days after application. No corn injury was observed on June 28 from the late postemergence (LPOST) treatment, seven days after application. Several EPOST and MPOST treatments continued to demonstrate corn injury on the final observation date of July 13, although it was considered insignificant.

Two-pass treatments comprised of PRE plus EPOST, MPOST or LPOST gave 90% or higher giant foxtail, velvetleaf, common waterhemp and common lambsquarters control when observed on July 13. An exception was PRE applied Harness Xtra plus EPOST Roundup PowerMAX which gave 75% velvetleaf control. One-pass EPOST treatments gave 92% or higher giant foxtail, velvetleaf, common waterhemp and common lambsquarters control on July 13. Exceptions to this were EPOST applied SureStart plus Roundup PowerMAX, Roundup PowerMAX plus MON 63410 plus Stinger and Roundup PowerMAX plus MON 63410 plus Impact which gave 75%, 78% and 73% velvetleaf control, respectively.

Iowa State University Postemergence applications of Callisto Xtra, Laudis, Impact, Status and Halex GT in corn, Ames,IA, 2010.

Trial ID: ACC 9 Protocol ID: HAJM06A4-2010USLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate postemergence applications in corn of

Callisto Xtra, Laudis, Impact, Status, and Halex GT for crop phytotoxicity, weed control and yield.

Conclusions:Corn stand differences were significant in comparing the herbicide treatments to the

untreated control. Moderate to heavy grass pressure in the untreated control resulted in a corn stand loss. All treatments exhibited excellent crop safety on all observation dates. Treatments that included Touchdown Total gave 93 to 99% giant foxtail, velvetleaf, common waterhemp and common lambsquarters control when observed on June 21, twenty days after application. Callisto Xtra, Laudis, Impact and Status applied without Touchdown Total gave 18 to 38% giant foxtail control, 65 to 99% velvetleaf control, 99% common waterhemp control, and 40 to 99% common lambsquarters control on June 21.

Touchdown Total gave 73% giant foxtail control when observed on July 3, thirty-two days after application, while Callisto Xtra (24.0 fl oz/A) plus Touchdown Total and Halex GT plus Atrazine gave 92% and 96% control, respectively. Giant foxtail control remained poor and ranged from 15 to 25% with Callisto Xtra, Laudis, Impact and Status, applied alone. On July 3, velvetleaf control ranged from 48 to 99% with treatments that included Touchdown Total. Impact plus Touchdown Total and Touchdown Total, alone, gave 52 and 48% velvetleaf control, respectively, while remaining treatments gave 68 to 99% control. Callisto Xtra, Laudis and Status, all without Touchdown Total, gave 91 to 99% velvetleaf control on July 3, while Impact without Touchdown Total gave 68% control. Common waterhemp and common lambsquarters control on July 3 was 82 to 99% with treatments that included Touchdown Total. Exceptions were Impact plus Touchdown Total and Touchdown Total, alone, which gave 47 to 73% common waterhemp and common lambsquarters control on July 3. Common waterhemp control with Callisto Xtra, Laudis, Impact and Status without Touchdown Total ranged from 90 to 99% on July 3. Common lambsquarters control ranged from 37 to 99% with the same treatments. Corn yields ranged from 154 to 190 bu/A with the herbicide treatments. Significant differences between treatments were observed. All treatments yielded significantly higher than the untreated control.

Trial ID: ACC 10 Protocol ID: GWN-10-03Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to compare the postemergence and residual control

profile of GWN-3041, GWN-3114 and Yukon to other programs in corn.

Conclusions:Significant differences determined between several treatments for corn stand were

attributed to variability in stand establishment and not herbicide treatment. Early postemergence (EPOST) applied treatments resulted in 0 to 13% corn injury when observed on June 1 and 7, seven and thirteen days after application. EPOST treatments gave 82 to 99% grass control and 99% velvetleaf, common waterhemp and common lambsquarters control on June 7. Woolly cupgrass followed by giant foxtail were the predominant grass species occurring in the study.

Mid-postemergence (MPOST) treatments did not result in corn injury when observed on June 17, seven days after application. MPOST treatments gave 93 to 98% grass control and 91 to 99% velvetleaf, common waterhemp and common lambsquarters control on June 25.

Late-season grass control with EPOST Lumax on August 20, eighty-seven days after application, was 63%. EPOST GWN-3041 plus GWN-3114 plus Atrazine gave 75% grass control, while EPOST Balance Flexx plus Atrazine gave 87% grass control. Velvetleaf and common waterhemp control on August 20 with EPOST treatments ranged from 83 to 93%, while common waterhemp control was 99%. MPOST treatments gave 85 to 93% grass control on August 20, seventy-one days after application. MPOST applied Roundup PowerMAX gave 70 to 78% velvetleaf, common waterhemp and common lambsquarters control on August 20. Remaining MPOST treatments gave 88 to 95% velvetleaf, 80 to 88% common waterhemp and 91 to 98% common lambsquarters control. The high LSD for corn yield at 54.8 bushels was due in part to stand variability and poor soil drainage. Corn yields with the herbicide treatments were low and ranged from 125 to 159 bu/A. Almost all of the treatments yielded significantly higher than the untreated control. (Dept. of Agronomy, Iowa State University, Ames).

Country: USA

Objectives:The purpose of this study was to evaluate postemergence applications in corn of Halex

GT, Laudis, SureStart, Durango DMA, Capreno, Status, Roundup PowerMAX and Lumax for phytotoxicity, weed control and yield.

Conclusions:Significant corn stand differences between several treatments were attributed to

variability in stand establishment and not herbicide treatment. No corn injury was apparent from the early postemergence (EPOST) applied treatments when observed June 9, two days following application. However, several EPOST treatments did exhibit 2 to 7% injury on June 14 and 21, seven and fourteen days after application. On June 21, good to excellent weed control overall was observed with the EPOST treatments and ranged from 95 to 99%. Woolly cupgrass followed by giant foxtail were the predominant grass species occurring in the study.

EPOST and EPOST plus LPOST treatments gave 85 to 95% late-season grass control when observed on August 20, seventy-four days after application. EPOST Roundup PowerMAX, applied alone, was an exception where 78% grass control was observed. On August 20, EPOST Roundup PowerMAX, applied alone, gave 65% velvetleaf control, while remaining treatments gave 88 to 99% velvetleaf control. EPOST applied SureStart plus Durango DMA, EPOST Status plus Roundup PowerMAX and EPOST Roundup PowerMAX gave 78%, 65% and 63% common waterhemp control on August 20, respectively, while remaining treatments gave at least 88% control. Common lambsquarters control on August 20 ranged from 87 to 99% with the EPOST and EPOST plus LPOST treatments. Exceptions to this were EPOST applied Status plus Roundup PowerMAX and EPOST Roundup PowerMAX which gave 68 and 58% common lambsquarters control, respectively. All herbicide treatments yielded significantly higher than the untreated control. Corn yields with the herbicide treatments ranged from 150 to 179 bu/A with significant differences occurring between several treatments. (Dept. of Agronomy, Iowa State University, Ames).

Iowa State University Impact applied postemergence with various tank-mix partners in corn, Ames, IA, 2010.

Trial ID: ACC 12 Protocol ID: 2010-Impact trialLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate the crop phytotoxicity and weed control

performance of Impact in sequential weed control programs and in tank-mixes with Roundup PowerMAX in corn.

Conclusions:Variability in stand establishment resulted in significant differences between several

treatments for corn stand. Preemergence (PRE) followed by early postemergence (EPOST) applied treatments exhibited little to no corn injury when observed on June 10 and 18, five and thirteen days following application. PRE plus EPOST applied treatments gave 95 to 99% weed control overall on June 18. On June 21, ten days after application, grass control with the PRE plus POST treatments ranged from 75 to 88%. Woolly cupgrass followed by giant foxtail were the predominant grass species occurring in the study. Velvetleaf, common waterhemp and common lambsquarters control with the PRE plus POST treatments ranged from 90 to 99% on June 21. PRE plus POST applied treatments gave 83 to 88% ivyleaf morningglory control on June 21.

Grass and velvetleaf control with the PRE plus EPOST and PRE plus POST treatments was 88 to 98% when observed on August 11, sixty-seven and sixty-one days following their application, respectively. PRE plus EPOST and PRE plus POST treatments gave 80 to 99% common waterhemp and common lambsquarters control on August 11. PRE applied Dual Magnum II plus POST Roundup PowerMAX was an exception where 75% common waterhemp and common lambsquarters control was achieved. Ivyleaf morningglory control on August 11 ranged from 72 to 85% with the PRE plus EPOST and PRE plus POST treatments. Herbicide treatment corn yields ranged from 85 to 190 bu/A and significant differences between several treatments were determined. The untreated control yielded significantly less corn than all herbicide treatments. (Dept. of Agronomy, Iowa State University, Ames).

Iowa State University Preemergence applications of GWN-3039, GWN-3041, GWN-3114 and Lumax in corn, Ames, IA, 2010.

Trial ID: GowanCorn#2 Protocol ID: GWN-10-04Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate crop phytotoxicity and weed control in corn

from applications of GWN-3039 and GWN-3041, GWN-3114 and compared to Lumax.

Conclusions:Corn stands were quite variable, however, no significant differences were observed between

the preemergence (PRE) applied treatments. Treatments exhibited excellent crop safety on all observation dates. Grass control with the treatments was 67 to 90% when observed on June 1, twenty-six days after application. Grass species occurring in the study were predominantly woolly cupgrass followed by giant foxtail. Velvetleaf control on June 1 was 98% with Lumax. The remainder of the treatments provided 83 to 87% velvetleaf control. On June 1 the treatments gave 96 to 99% common waterhemp and common lambsquarters control and 80 to 83% ivyleaf morningglory control.

Late-season weed control observations were made on July 22, seventy-seven days following the PRE treatment application date. Lumax continued to provide better grass control at 77% compared with the remaining treatments which gave 42 to 47%. Broadleaf weed control was 99% with the treatments on July 22. Ivyleaf morningglory was an exception where 45 to 52% control was provided by the treatments. Variable corn stands, high grass populations and poor control by the treatments resulted in very low corn yields. Yields ranged from 72 to 137 bu/A. Lumax provided significantly higher corn yield than the untreated control. (Dept. of Agronomy, Iowa State University, Ames).

Iowa State University Impact applied postemergence with various tank-mix partners for woolly cupgrass control incorn, Ames, IA, 2010.








Country: USA



Conclusions:Differences in corn stand between treatments were not significant. No early postemergence

(EPOST) applied treatment resulted in corn injury on any observation date. On June 21, fourteen days after application, treatments gave 96 to 99% control of the weed species observed in the study area.

Treatments gave 93 to 95% woolly cupgrass, 88 to 92% velvetleaf, 90 to 95% common waterhemp, 94 to 99% common lambsquarters, and 87 to 90% ivyleaf morningglory control on July 7, thirty days after EPOST application timing. Velvetleaf control with PRE applied Harness plus EPOST Roundup PowerMAX was an exception where 80% control was observed. Treatments gave 87% or higher woolly cupgrass, velvetleaf, common waterhemp, common lambsquarters and ivyleaf morningglory control on August 11, sixty-five days after EPOST treatment timing. Velvetleaf control with PRE Harness plus EPOST Roundup PowerMAX was again the exception where 80% control was observed. Corn yields with the herbicide treatments ranged from 144 to 170 bu/A. Herbicide treatment corn yields were significantly higher than the untreated control. (Dept. of Agronomy, Iowa State University, Ames).

preemergence and/or postemergence applications of SureStart, Durango DMA, Atrazine, Halex GT, Lumax, Touchdown Total, Solida, Nic-It and Glyfos Xtra.

Conclusions:No corn injury was observed on June 15 from the preemergence (PRE) applied treatments

prior to the mid-postemergence (MPOST)) treatment timing. Reduced application rates of the PRE treatments gave 68 to 78% grass, 53 to 85% velvetleaf, 88 to 98% common waterhemp and 92 to 96% common lambsquarters control on June 15. Woolly cupgrass followed by giant foxtail were the predominant grass species occurring in the study. Postemergence (POST) treatments resulted in 0 to 10% corn injury when observed on June 15, eight days after application. Overall weed control with the POST treatments on June 15 was 95 to 99%.

No corn injury was noted from POST or MPOST applied treatments when observed on June 21, fourteen and six days after application, respectively. PRE plus MPOST treatments gave 87 to 99% and POST treatments gave 98 to 99% weed control overall when observed on June 21.

Grass, common waterhemp, common lambsquarters and ivyleaf morningglory control ranged from 88 to 99% with the PRE plus MPOST treatments on July 15. Velvetleaf ranged from 85 to 96% with the PRE plus MPOST treatments. POST applied Halex plus Atrazine gave 90 to 99% weed control overall on July 15, while remaining POST treatments gave 52 to 98%.

Country: USA


GT, Callisto and Touchdown Total with and without Quadris fungicide for phytotoxicity, vigor, foliar disease severity, senescence and yield.

Conclusions:No significant differences in corn stand between treatments were determined. Corn injury

ranging from 0 to 7% was observed from the postemergence (POST) applied treatments on June 10 and 16, six and twelve days after application. Corn vigor was excellent (excellent = 5) with all treatments when observed on June 16. Corn injury was observed on July 2 from a number of POST treatments, however, injury was considered minor.

Corn exhibited 70%, 99% and 99% disease incidence when observed on July 29, August 19 and 26, respectively. Corn diseases included common rust and gray leaf spot. On July 29, August 19 and August 26, disease severity present on corn leaves ranged from 3 to 7%, 23 to 33% and 25 to 30%, respectively. Corn yields ranged from 182 to 203 bu/A. Differences in yield between the treatments were not significant. (Dept. of Agronomy, Iowa State University, Ames).

Country: USA

Objectives:The purpose of this study was to evaluate fall applications of Optill, Sharpen,

Scepter, Canopy EX, Valor XLT and Enlite for crop phytotoxicity and weed control in no-tillage soybean production.

Conclusions:Fall (FALL) applied treatments did not cause soybean injury. On May 4, FALL treatments,

except Roundup PowerMAX applied alone, provided at least 96% common lambsquarters control. Treatments of Canopy EX and Valor XLT gave 93 and 98% common dandelion control, respectively. Common dandelion control by other treatments ranged from 33 to 73%. Canopy EX and Valor XLT each provided 93% giant foxtail control on June 1, and remaining treatments gave 65 to 87% control. Sharpen plus Scepter, Canopy EX, Valor XLT and Enlite treatments provided 93 to 99% common lambsquarters control. Optill treatments gave 83 to 87% common lambsquarters control. Canopy EX and Valor XLT gave 90 to 95% common dandelion control while the other treatments gave less than 70% control.

June 25 observations showed that giant foxtail and common dandelion control diminished significantly for many of the treatments, while common lambsquarters control was maintained. On July 27, twenty-eight days after the POST application timing, common lambsquarters control was 85% for the FALL application of Roundup PowerMAX, and 91 to 99% for FALL treatments with residual herbicides. All treatments provided 99% giant foxtail control. Canopy EX afforded 96% common dandelion control on July 27, and the remaining treatments gave 63 to 88% control.

Iowa State University Preplant burndown and postemergence applications of Tackle and Extreme in no-tillage soybean,Ames, IA, 2010.

Trial ID: ASN 2 Protocol ID: HGLXMATAC100Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to determine the effectiveness and selectivity of Tackle

and Extreme when applied preplant as a burndown and postemergence in no-tillage soybean production.

Conclusions:No early preplant (EPP) treatment caused more than 3% soybean injury on June 14. EPP

applied Tackle treatments gave significantly greater giant foxtail, common lambsquarters and common dandelion control than Glyfos X-tra treatments when observed May 25, fifteen DAA (days after application). On June 14, thirty-five DAA, EPP applied Glyfos X-tra provided no more than 45% control for any of the weed species. EPP applied Tackle treatments, however, provided 83 to 95% giant foxtail, velvetleaf, common waterhemp and common lambsquarters control. Common dandelion control by EPP applied Tackle was 52 to 55%.

On June 21, six days after the postemergence (POST) application timing, Tackle and Extreme treatments caused 20 to 35% stunting, 13 to 18% chlorosis and 5 to 13% necrosis. Soybean stunting from the POST treatments was still apparent on July 13, however, the chlorosis and necrosis had disappeared. On June 29, fourteen days after POST treatment timing, weed control ranged from 92 to 99% and few significant differences between treatments were observed. By July 22, there were no significant weed control differences between any of the POST herbicide treatments, and ranged from 85 to 99%. EPP applied Tackle, without a POST application, afforded 88% velvetleaf control, while control of other weeds ranged from 53 to 75%. (Dept. of Agronomy, Iowa State University, Ames).

Trial ID: ASN 3 Protocol ID: USA-10-151Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate various herbicides and application timings

for crop phytotoxicity, weed control and yield in GAT soybean.

Conclusions:None of the herbicide treatments caused soybean injury. On May 25, eight days after

application (DAA) timing, early preplant (EPP) treatments afforded 99% giant foxtail and common lambsquarters control. Common dandelion control ranged from 68 to 98%. On June 8, twenty-two DAA, giant foxtail control did not exceed 88% for any of the EPP treatments, however, common lambsquarters control remained essentially unchanged. EPP applied Diligent WP plus Roundup PowerMAX plus 2,4-D LV4 afforded 99% dandelion control on June 8, compared to 82 and 83% control by the Roundup PowerMAX plus 2,4-D LV4 treatments. Giant foxtail control on June 25 ranged from 50 to 99%, while common lambsquarters and common dandelion control ranged from 95 to 99%.

Following the application of all postemergence (EPOST, POST, LPOST) treatments, 98 to 99% weed control was observed on August 11. An exception was EPP applied Roundup PowerMAX plus 2,4-D LV4 followed by EPOST and LPOST Roundup PowerMAX which gave 93% giant foxtail control. There were no significant soybean yield differences between herbicide treatments which ranged from 59 to 65 bu/A. (Dept. of Agronomy, Iowa State University, Ames).

Iowa State University Preplant applications of 2,4-D LV4, Sharpen, Optill, Extreme, and Prowl H2O with Roundup PowerMAXin no-tillage soybean production, Ames, IA, 2010.

Trial ID: ASN 4 Protocol ID: BASF Kixor 12Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate preplant applications of 2,4-D LV4, Sharpen,

Optill, Extreme, and Prowl H2O with Roundup PowerMAX for crop phytotoxicity and weed control in no-tillage soybean.

Conclusions:None of the herbicide treatments caused injury to soybean at any time. On May 20, six

days after application (DAA), early preplant (EPP) treatments with Roundup PowerMAX, alone, or with 2,4-D LV4 did not provide burndown control of common lambsquarters and common dandelion as quickly as EPP treatments that included Sharpen or Optill. On June 4, twenty-one DAA, giant foxtail control ranged from 65 to 92%, common lambsquarters control was 98% or better and common dandelion control ranged from 91 to 99% with the EPP treatments. On June 29, only EPP applied Optill or Sharpen plus Extreme tank-mixed with Roundup PowerMAX provided acceptable giant foxtail control with 90 and 92%, respectively. EPP Sharpen plus Prowl H2O plus Roundup PowerMAX and Sharpen plus Roundup PowerMAX gave 63 and 70% common dandelion control, respectively. The remaining treatments afforded at least 87% common dandelion control. Common lambsquarters control on June 29 changed very little in comparison to June 6 observations.

On July 28, thirty days after the POST application, all treatments provided at least 98% giant foxtail and common lambsquarters control. Common dandelion control ranged from 88 to 98%. (Dept. of Agronomy, Iowa State University, Ames).

Trial ID: ASN 5 Protocol ID: HP10NARMRALocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate burndown and residual weed control with

early preplant applied Ignite 280 with various tank-mix partners including Sharpen, Sencor, Envive, Sonic, Valor XLT, Prefix, Optill and Authority MTZ in no-tillage soybean production.

Conclusions:None of the treatments resulted in soybean injury. Early preplant (EPP) treatments gave

at least 98% control of all weeds when observed on May 25, eleven days after application (DAA). On June 21, thirty-seven DAA, EPP applied Ignite 280 plus Envive and Ignite 280 plus Optill provided 90% giant foxtail control and at least 95% velvetleaf, common waterhemp, common lambsquarters, horseweed and prickly lettuce control. No other EPP treatments provided more than 80% giant foxtail control. EPP treatments gave 17 to 99% velvetleaf, 13 to 99% common waterhemp, 96% or better horseweed and dandelion, and 98% or better prickly lettuce control on June 21. EPP applied Ignite 280, without a tank mixture, however, provided 86% prickly lettuce control.

On July 26, thirty-four days after mid-postemergence (MPOST) application timing, treatments gave at least 93% velvetleaf, common lambsquarters, horseweed, prickly lettuce and dandelion control. Giant foxtail and common waterhemp control ranged from 87 to 93% and 86 to 99%, respectively. Soybean yields by herbicide treatments ranged from 61 to 63 bu/A with no significant differences between treatments. (Dept. of Agronomy, Iowa State University, Ames).

Trial ID: ASN 6 Protocol ID: FMCLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate soybean phytotoxicity and weed control from

Authority Assist, Sharpen, Valor XLT, Authority XL, and Optill applications in no-tillage soybean.

Conclusions:The early preplant (EPP2) application timing of Authority XL plus Rage D-Tech plus Roundup

PowerMAX provided at least 98% weed control on May 25, eight days after application (DAA). On May 25, EPP2 applied Authority Assist plus Sharpen plus Roundup PowerMAX gave 99, 96, 99 and 90% giant foxtail, common lambsquarters, horseweed and common dandelion control, respectively. Residual control for the same treatment applied as an EPP1 had diminished significantly for each of the above mentioned weeds when observed on the same date (May 25, fifteen DAA).

Preemergence (PRE) treatments caused no more than 5% injury as noted on June 11, seventeen days after application. On June 11, EPP1, EPP2 and PRE treatments demonstrated at least 90% giant foxtail and 94% horseweed control, respectively. Common lambsquarters and common dandelion control ranged from 75 to 99% and 82 to 98% for the treatments, respectively. Treatments gave 94 to 99% horseweed control. Weed control for many of the treatments was reduced when observed on June 29, thirty-five days after PRE application timing.

The postemergence (POST) treatment of Roundup PowerMAX caused negligible soybean injury not exceeding 8% on July 13, fourteen days DAA. On July 28, twenty-nine days after the postemergence (POST) treatments were applied, giant foxtail, common lambsquarters and horseweed control was at least 93%. Common dandelion control ranged from 87 to 99% on July 28. (Dept. of Agronomy, Iowa State University, Ames).

Iowa State University Postemergence applications of Ignite 280 in soybean, Ames, IA, 2010.

Trial ID: ASC 1 Protocol ID: HP10NARMRBLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate various postemergence application timings of

Ignite 280 for crop phytotoxicity and weed control in soybean.

Conclusions:Postemergence (POST) treatments of Flexstar, Cobra and Cadet caused 15, 27 and 12% soybean

injury on June 29, eight days after application (DAA). Injury caused by other treatments ranged from 0 to 7%. On June 29, there was no significant rate response with POST applied Ignite 280 for giant foxtail, velvetleaf and common lambsquarters control at rates ranging from 22 to 36 fl oz/A. However, common waterhemp control ranged from 83 to 93% for those rates. Weed control for the POST applied treatments of the 22 fl oz/A rate of Ignite 280, with and without a tank mixture, ranged from 83 to 99%.

Soybean injury from Cobra was at 20% and no other treatments exceeded 10% injury, on July 7 (sixteen DAA). On July 7, Ignite 280 applied at 22 fl oz/A, alone, and with Select MAX, provided 85% common waterhemp control. Weed control with all other treatments on July 7 was at least 90%.

Giant foxtail, velvetleaf and common lambsquarters control was at least 93% for all treatments on August 5. Common waterhemp control was greater for treatments with a late application or two applications. There were no significant soybean yield differences between any of the herbicide treatments.

Iowa State University Preemergence applied Prefix and Prowl H20 followed by postemergence applied Ignite 280 andpostemergence applied Outlook, FirstRate and others in tank-mixture with Ignite 280, Ames, IA,2010.

Trial ID: ASC 2 Protocol ID: HP10NARMRCLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate soybean phytotoxicity and weed control in

two and one-pass weed management programs. Treatments evaluated included preemergence applied Prefix followed by postemergence applied Ignite and postemergence applied Outlook, FirstRate and others in tank-mixture with Ignite 280.

Conclusions:Preemergence (PRE) treatments did not cause more than 5% injury to soybean when observed

on June 10. PRE applied Prefix provided 93 and 99% giant foxtail and common waterhemp control, respectively, while velvetleaf and common lambsquarters control was not greater than 50%. PRE applied Prowl H2O provided 83% giant foxtail and 99% common waterhemp and common lambsquarters control. Velvetleaf control by Prowl H2O was 72%.

Soybean injury caused by early postemergence (EPOST) treatments was 27, 20 and 10% for Ignite 280 plus Prefix, Ignite 280 plus Outlook and Ignite 280 plus Dual II Magnum, respectively, when observed on June 16, six days after application (DAA). Injury from remaining EPOST treatments did not exceed 5%. EPOST treatments provided at least 90% control of all weeds as observed June 21, eleven DAA.

Treatments with mid-postemergence (MPOST) applied Ignite 280 gave 88 to 90% velvetleaf control on July 15, twenty-four DAA. MPOST applied Ignite 280 following Prefix, afforded at least 98% giant foxtail, common waterhemp and common lambsquarters control. MPOST applied Ignite 280 following Prowl H2O afforded 90 to 93% giant foxtail, common waterhemp and common lambsquarters control.

The EPOST plus late postemergence (LPOST) treatment of Ignite 280 provided significantly greater weed control than many of the other treatments on July 27. Soybean yields ranged from 53 to 59 bu/A for the treatments, excluding the untreated control. (Dept. of Agronomy, Iowa State University, Ames).

preemergence applied Authority XL, Authority First, Authority Assist, Valor XLT, Prefix and Optill followed by postemergence applied Ignite 280.

Conclusions:Soybean injury from preemergence (PRE) treatments did not exceed 5% when observed on June

7. Ten percent soybean injury was observed on June 21 for early postemergence (EPOST) applied Ignite 280, six days after application (DAA). The EPOST Ignite 280 treatment provided at least 95% giant foxtail, velvetleaf, common waterhemp and common lambsquarters control on June 21.

On June 28, soybean injury from postemergence (POST) applied Ignite 280 treatments ranged from 10 to 13%, seven DAA. On July 16, POST applied Ignite 280 treatments provided 90 to 99% control of all weeds. The sequential (SPOST) Ignite 280 treatment provided 99% control of all weeds, and the PRE plus POST treatments afforded at least 90% weed control on July 29. The single POST applied Ignite 280 treatment gave 87% common ragweed control and 92 to 93% control of the remaining weeds. Soybean yields for the treatments, excluding the control, ranged from 58 to 65 bu/A with no significant differences between them.

Iowa State University Postemergence applications of Rhythm, Dawn, and Flexstar in soybean, Ames, IA, 2010.

Trial ID: ASC 4 Protocol ID: HGLXMAFOMME100Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate crop phytotoxicity and weed control in

soybean from postemergence applied Rhythm, Glyfos-Xtra, Dawn and Flexstar.

Conclusions:Soybean chlorosis from the postemergence (POST) applied treatments was consistently 5%

when observed on July 8, thirteen days after application (seven days after sequential postemergence (SPOST) application timing). Soybean necrosis and stunting, ranging from 8 to 15 and 0 to 10%, respectively, was rate responsive (10 to 40 fl oz/A) for POST applied Rhythm plus MSO. POST applied Flexstar, at 20 fl oz/A, caused 12% necrosis. The 10 fl oz/A rate of POST applied Flexstar, Dawn, and Rhythm plus Glyfos X-tra treatments did not cause more than 8% chlorosis, necrosis or stunting of the soybeans on July 8.

Giant foxtail control responded significantly to herbicide rate on July 8 with greater control for higher rates of POST applied Rhythm plus MSO and POST applied Flexstar treatments. Velvetleaf and common waterhemp control was at least 96% for the same treatments. POST applied Rhythm plus Glyfos-Xtra provided at least 95% control of all weeds. POST applied Dawn gave 82, 78 and 99% giant foxtail, velvetleaf and common waterhemp control, respectively.

On July 23, only the 40 fl oz/A rate of POST applied Rhythm plus MSO and 20 fl oz/A rate of Flexstar still showed soybean stunting at 7 and 5%, respectively. Necrosis ranged from 3 to 5% for all herbicide treatments. Only the 20 fl oz/A rate of Rhythm plus Glyfos X-tra treatment caused chlorosis, with 3%. All treatments afforded 91% or better weed control when observed on July 29. An exception was POST applied Dawn followed by Select MAX which gave 67% velvetleaf control.

Trial ID: ASC 5 Protocol ID: HGLXMACLOM1001Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate preemergence applied Alert, CHA-019, CHA-

021, Dawn, Metribuzin, and Command for soybean phytotoxicity and weed control.

Conclusions:Soybean injury from the treatments did not exceed 2% stunting or necrosis and there was no

observed chlorosis when observed on June 7, sixteen days after preemergence (PRE) treatments were applied. On June 26, Alert, without a tank mix partner, provided significantly different giant foxtail and velvetleaf control only when comparing the highest and lowest rates (16 and 42.7 fl oz/A). Common waterhemp control, however, was significantly greater with each Alert application rate increase. Other herbicide treatment rate comparisons for CHA-019, CHA-021 and Alert plus Dawn did not show significant weed control differences for varied herbicide rates. All herbicide treatments provided at least 93% common lambsquarters control on June 26. Metribuzin, Dawn and Command 3 ME showed no significant giant foxtail or common lambsquarters control differences, but did vary for velvet leaf and common waterhemp control. Weed control trends on July 20 were very similar to those observed on June 26. (Dept. of Agronomy, Iowa State University, Ames).

Iowa State University Two-pass weed management in soybean. Preemergence applied Authority XL, Authority First,Authority Assist, Valor XLT, Prefix and Optill followed by postemergence applied RoundupPowerMAX, Ames, IA, 2010.








Country: USA


preemergence applied Authority XL, Authority First, Authority Assist, Valor XLT, Prefix and Optill followed by postemergence applied Roundup PowerMAX.

Conclusions:Soybean injury did not exceed 5% for any preemergence (PRE) treatments when observed on

June 7. Giant foxtail and yellow foxtail control ranged from 65 to 85% for PRE applied Authority XL, and Authority First treatments when observed on June 25. PRE applied Authority Assist, Valor XLT, Prefix and Optill provided 93 to 99% giant foxtail and yellow foxtail control. PRE applied Valor XLT and Optill gave 95% velvetleaf control, and the remaining PRE treatments gave 60 to 85% velvetleaf control. All PRE treatments gave at least 96% common waterhemp control on June 25.

No soybean injury was caused by the postemergence and sequential postemergence (POST, SPOST) treatments. On July 29, all treatments provided at least 96% control of all weeds. Soybean yield for herbicide treatments ranged from 55 to 61 bu/A with few significant differences between treatments. Some variability in soybean yield results may have been due to saturated soil conditions in part of the experiment for much of the growing season.

Iowa State University Postemergence applications of Roundup PowerMAX, Resource, V-10206 and Prefix in soybean, Ames,IA, 2010.

Trial ID: ASC 7 Protocol ID: VUSA2010V10206MD64.02Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to determine if the addition of V-10206 to Resource plus

Roundup PowerMAX can increase the postemergence control of weeds and add residual control compared to Resource plus Roundup PowerMAX.

Conclusions:Postemergence (POST) applications of Roundup PowerMAX, applied alone, did not cause

soybean injury when observed on July 2. However, when Roundup PowerMAX was tank-mixed with Resource, Resource plus V-10206, and Prefix, soybean injury was 5, 7 and 15%, respectively.

On July 8, Roundup PowerMAX plus Resource or Resource with V-10206 caused 5% injury, and Roundup PowerMAX plus Prefix caused 13% soybean injury. Roundup PowerMAX plus Prefix afforded slightly less, yet statistically significant, giant foxtail control than Roundup PowerMAX and Roundup PowerMAX plus Resource or Roundup PowerMAX plus Resource and V-10206. Roundup PowerMAX provided 95% velvetleaf control compared to at least 98% control by treatments of Roundup PowerMAX that include a tank mix herbicide.

On July 23, treatments provided similar giant foxtail control compared to observations from July 8. There were no significant treatment differences between treatments for velvetleaf control. Roundup PowerMAX plus Prefix gave 93% common waterhemp control, and the remaining treatments gave 78 to 83%. (Dept. of Agronomy, Iowa State University, Ames).

Iowa State University Postemergence applications of Flexstar GT, Resource, Cadet, Roundup PowerMAX and Cobra insoybean, Ames, IA, 2010.

Trial ID: ASC 8 Protocol ID: HDEB02A4-2010USLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate Flexstar GT, Resource, Cadet, Roundup

PowerMAX and Cobra applied postemergence in soybean for crop phytotoxicity and weed control.

Conclusions:Mid-postemergence (MPOST) applied Flexstar GT treatments caused 10% soybean injury On July

7, six days after application (DAA). Cadet plus Roundup PowerMAX and Cobra plus Roundup PowerMAX caused 13 and 25% injury, respectively. Grass weeds in this experiment consisted of a giant and yellow foxtail mixture. MPOST applied Flexstar GT, Roundup PowerMAX, Cadet plus Roundup PowerMAX and Resource plus Roundup PowerMAX provided 80 to 83% grass control on July 7. MPOST applied Cobra plus Roundup PowerMAX gave 90% grass control. EPOST applied Flexstar GT, Roundup PowerMAX and MPOST applied Flexstar GT following PRE applied Boundary gave at least 98% grass control. MPOST and EPOST applied Roundup PowerMAX provided 77 to 83% velvetleaf and common waterhemp control, while EPOST applied Roundup PowerMAX (18 fl oz/A) gave 67 and 63% velvetleaf and common waterhemp control, respectively. MPOST applied Flexstar GT, Resource plus Roundup PowerMAX, Cadet plus Roundup PowerMAX and EPOST applied Flexstar GT gave 85 to 99% velvetleaf and common waterhemp control.

On July 27, twenty-six DAA, 12% soybean injury was still apparent for MPOST applied Cobra plus Roundup PowerMAX. All treatments provided at least 92, 92 and 95% control of grass, velvetleaf and common waterhemp, respectively. However, there were still small, statistically significant differences in weed control between some of the treatments. Flexstar GT, applied MPOST at 38 fl oz/A provided significantly greater soybean yield (67 bu/A) than many other herbicide treatments that gave soybean yields from 58 to 63 bu/A. However, some of the other herbicide treatments provided very similar weed control levels since the July 7 observation date. (Dept. of Agronomy, Iowa State University, Ames).

Trial ID: ASC 9 Protocol ID: Dow/Dupont/ValentMD64.02Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate preemergence applied Sonic, Enlite, Envive,

Valor SX, Prowl H20 and Fierce and postemergence applied Durango DMA, FirstRate, and Roundup PowerMAX in soybean.

Conclusions:Preemergence (PRE) treatments did not cause more than 5% soybean injury when observed on

June 7. Giant foxtail and velvetleaf control by PRE treatments ranged from 60 to 98 and 82 to 99%, respectively, on June 30. Common waterhemp and common lambsquarters control was at least 95% for all PRE treatments.

Early postemergence (EPOST) applied Durango plus FirstRate caused 8% injury on July 7, eight days after application. Observations on July 7 showed similar weed control trends compared to June 30 except for velvetleaf control by PRE applied Prowl H2O. All treatments afforded at least 98% weed control from July 27 to August 18 following all postemergence application timings. (Dept. of Agronomy, Iowa State University, Ames).

Trial ID: ASC 10 Protocol ID: HCNN02A4-2010USLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate two and one-pass weed management programs in

soybean for crop phytotoxicity, weed control and yield.

Conclusions:No preemergence (PRE) treatments caused greater than 3% soybean injury on June 7. All PRE

treatments afforded at least 98% common lambsquarters control and 95% common waterhemp control on June 30. Giant foxtail control by PRE treatments was variable, ranging from 60 to 99%. Valor XLT gave 99% velvetleaf control, and the remaining PRE treatments provided 80 to 92% velvetleaf control.

Early postemergence (EPOST) applied Prefix plus Touchdown Total and MON 63410 plus Roundup PowerMAX caused 17 and 7% soybean injury, respectively, when observed June 30, five days after application. On July 8, EPOST treatments gave at least 98% giant foxtail, common waterhemp and common lambsquarters control. Velvetleaf control, however, ranged from 87 to 96% for EPOST treatments. On July 27, all treatments demonstrated at least 96% weed control, fourteen days after the late postemergence (LPOST) treatments were applied. Soybean yields ranged from 53 to 59 bu/A, including the untreated control, because of generally light weed pressure and adequate soil moisture.

Iowa State University Cadet and Resource applied postemergence with Roundup PowerMAX in soybean, Ames, IA, 2010.








Country: USA

Objectives:The purpose of this study was to evaluate Cadet and Resource applied postemergence

with Roundup PowerMAX for crop phytotoxicity and weed control in soybean.

Conclusions:Early postemergence (EPOST) applied Cadet with Roundup PowerMAX and Resource with Roundup

PowerMAX caused 8 and 5% soybean injury, respectively, when observed on July 2, seven days after application (DAA). There were no significant giant foxtail control differences between any of the herbicide treatments. EPOST applied Cadet and Resource, when tank-mixed with Roundup PowerMAX, provided very similar velvetleaf, common waterhemp and common lambsquarters control. Either tank-mixture provided significantly greater control of these broadleaf weeds than Roundup PowerMAX provided, alone.

Cadet and Resource EPOST applied treatments caused 5% soybean injury on July 8, thirteen DAA. These treatments afforded greater velvetleaf control on July 8 than Roundup PowerMAX, alone. However, common waterhemp and common lambsquarters control on July 8 were sometimes greater for Roundup PowerMAX without a tank mix partner. On July 23, all treatments provided complete control of all weeds fourteen days after the sequential postemergence (SPOST) application of Roundup PowerMAX.

Iowa State University Postemergence applications of Roundup PowerMAX, MON 63410, Extreme, and Dual II Magnum insoybean, Ames, IA, 2010.

Trial ID: ASC 12 Protocol ID: 2010-01-04-10Location: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to better understand how MON 63410 fits with soybean

herbicide systems including one pass two pass systems utilizing preemergence products.

Conclusions:No combinations of preemergence (PRE), early postemergence (EPOST), or late-postemergence

(LPOST) treatments caused more than 5% stunting or chlorosis to soybean when observed on July 2 and July 16. All treatments provided 99% giant foxtail control on July 22, thirteen days after the LPOST application timing. EPOST applied Roundup PowerMAX plus either MON 63410 or Dual II Magnum provided 88% velvetleaf control. LPOST applied Roundup PowerMAX gave 91% velvetleaf control. EPOST applied Extreme and treatments with PRE followed by EPOST or LPOST, and EPOST followed by LPOST treatments gave 96 to 99% velvetleaf control. EPOST applied Roundup PowerMAX plus MON 63410 and Extreme gave 83 and 90% common waterhemp control, respectively. Other treatments gave at least 96% common waterhemp control on July 22. All treatments provided at least 96% common lambsquarters control on July 22. Weed control trends observed on August 23 with the treatments were similar to that on July 22. Soybean yield ranged from 60 to 63 bu/A for herbicide treatments with no significant differences between them. (Dept. of Agronomy, Iowa State University, Ames).

Trial ID: ASC 13 Protocol ID: NumerousLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate postemergence applied Fusilade DX, Select

Max and Assure II in tank-mixture with glyphosate for glyphosate-tolerant corn control in soybean.

Conclusions:None of the herbicide treatments caused injury to soybean on any of the observation dates.

On July 8, seven days after the postemergence (POST) application timing, Fusilade DX with Roundup PowerMAX and Select MAX with Roundup PowerMAX gave 57 and 53% glyphosate resistant corn control, respectively. Assure II with Roundup PowerMAX afforded 68% glyphosate resistant corn control. Giant foxtail control ranged from 83 to 85%, and all treatments gave 73 and 80% velvetleaf and common waterhemp control, respectively, on July 8.

On July 16, fifteen days after application, Assure II still provided significantly greater glyphosate resistant corn control than Fusilade DX and Select Max with 99, 83 and 80%, respectively. On August 12, all herbicide treatments provided at least 96% glyphosate resistant corn control with no significant differences between treatments. There were no significant differences between herbicide treatments for giant foxtail, velvetleaf and common waterhemp control. No treatments provided less than 93% control of these weeds.

Trial ID: MSN 1 Protocol ID: USA-10-144Location: Chariton Study Director: Owen/Lux/Franzenburg/Grossnickle





Trial LocationCity: Chariton


Country: USA

Objectives:The purpose of this study was to evaluate Sharpen applied alone and in combination

with Canopy EX, Basis and Envive for burndown and residual weed control in no-tillage soybean production.

Conclusions:No herbicide treatments caused injury to soybean. On April 1, fall applied (FALL) Canopy

EX plus Roundup PowerMAX plus 2,4-D LV4 and Canopy EX plus Sharpen plus Roundup PowerMAX treatments provided significantly greater common dandelion control (93% each) than Valor SX plus Roundup PowerMAX plus 2,4-D LV4 and Sharpen plus Roundup PowerMAX treatments (80% each). The two FALL treatments that included Basis gave 87% common dandelion control on April 1. Control of common dandelion on April 20 by both FALL Canopy EX treatments improved to at least 95%. Conversely, common dandelion control by all other FALL treatments observed on April 20 decreased from control previously observed on April 1.

Early preplant (EPP) applied Envive and Sharpen treatments provided at least 93% common dandelion control on May 5, fifteen days after application. On June 30, Fall applied Canopy EX plus Roundup PowerMAX plus 2,4-D LV4 and EPP applied Envive plus Roundup PowerMAX plus 2,4-D LV4 provided 87 and 93% common dandelion control, respectively. None of the other treatments afforded more than 77% common dandelion control on June 30. (Dept. of Agronomy, Iowa State University, Ames).

Conclusions:No significant differences in corn stand between treatments were observed. None of the

treatments resulted in corn injury when observed on the various dates. On June 3, 95 to 99% woolly cupgrass, 67 to 98% velvetleaf, 96 to 99% common waterhemp, 91 to 99% common lambsquarters and 48 to 99% common dandelion control was observed with the early preplant (EPP) and preemergence (PRE) applied treatments, sixteen days after PRE treatment timing. An exception to this was the non-residual EPP applied Roundup PowerMAX treatment which provided 0% woolly cupgrass, velvetleaf, common waterhemp and common lambsquarters control.

EPP and PRE applied treatments provided 92 to 98% woolly cupgrass control, excluding EPP applied Roundup PowerMAX, when observed on June 17, thirty days after PRE treatment timing. These same EPP and PRE treatments gave 53 to 95% velvetleaf, 88 to 99% common waterhemp, 91 to 98% common lambsquarters and 68 to 99% common dandelion control. On July 2, fifteen days following the postemergence (POST) treatment timing, overall weed control by all treatments ranged from 87 to 99%. Weed control remained good to excellent with the treatments ranging from 90 to 99% on July 14, twenty-seven days after POST application timing.

Trial ID: LCN 2 Protocol ID: HP10NARJJBLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate burndown and residual weed control programs

including Corvus, 2,4-D LV4, Roundup PowerMAX, Laudis, Cadet, Capreno, Ignite 280 and Sharpen in no-tillage corn production.

Conclusions:Differences in corn stand were significant between several treatments. These differences

were attributable to variability in stand establishment and not herbicide treatment. Excellent crop safety was exhibited by the treatments. Treatments provided 90 to 99% woolly cupgrass, velvetleaf, common lambsquarters and common dandelion burndown control when observed on June 3, sixteen days after application. Residual weed control with the treatments on June 25, thirty-eight days following application, was 82% or higher. Exceptions to this were Capreno plus Roundup PowerMAX (77% woolly cupgrass and 50% velvetleaf control), Balance Flexx plus Roundup PowerMAX (65% velvetleaf control) and Ignite 280 plus Sharpen (68% woolly cupgrass, 37% velvetleaf and 78% common dandelion control).

Observations on July 22, sixty-five days after application, generally demonstrated a reduction in weed control from that noted on June 25. On July 22, woolly cupgrass control ranged from 68 to 93%, velvetleaf 37 to 90%, common waterhemp 92 to 99%, common lambsquarters 80 to 99% and common dandelion from 77 to 99%.

applications of Corvus, Atrazine, Balance Flexx, Capreno, Roundup PowerMAX, Laudis and Ignite for crop phytotoxicity and weed control in corn.

Conclusions:Corn stands were consistent and no significant differences between the treatments were

determined. Preemergence (PRE) treatments did not result in corn injury when observed on June 3, sixteen days after application. Early postemergence (EPOST) applied Corvus plus Atrazine, Balance Flexx plus Atrazine and Capreno plus Roundup PowerMAX caused 2 to 15% corn injury on June 9 and 17, six and fourteen days after application, respectively. Woolly cupgrass, velvetleaf, common waterhemp and common lambsquarters control ranged from 93 to 99% on June 17 with the EPOST treatments. On June 17, zero days prior to mid-postemergence (MPOST) treatment timing, preemergence (PRE) treatments gave 85 to 95% woolly cupgrass, 82 to 99% velvetleaf, 78 to 99% common waterhemp and 92 to 99% common lambsquarters control.

MPOST applied treatments of Capreno plus Roundup PowerMAX and Balance Flexx plus Capreno plus Roundup PowerMAX caused 7 to 10% corn injury when observed on June 25 and July 2, eight and fifteen days after application, respectively. Remaining MPOST treatments did not result in corn injury. PRE followed by MPOST and MPOST treatments gave 92 to 99% overall weed control on July 2. On July 14, all treatments continued to provide 90% or higher weed control. An exception to this was PRE applied Corvus plus Atrazine where 85% woolly cupgrass control was observed.

control. These stand differences were not due to herbicide treatment, but rather a result of heavy common dandelion pressure and variability in stand establishment. Treatments demonstrated excellent crop safety on all observation dates. On June 4, 90 to 98% giant foxtail, 75 to 98% velvetleaf, 99% common lambsquarters and 82 to 87% common dandelion control was observed with the early preplant (EPP)and preemergence (PRE)applied treatments, twenty-one days after PRE treatment timing. An exception was the non-residual treatment of EPP applied Roundup PowerMAX which gave no giant foxtail, velvetleaf and common lambsquarters control on June 4.

Giant foxtail control ranged from 87 to 92% with the EPP and PRE treatments, excluding EPP Roundup PowerMAX, when observed on June 16, thirty-three days after PRE application timing. These same EPP and PRE treatments gave 70 to 99% velvetleaf, 93 to 99% common waterhemp, 93 to 99% common lambsquarters and 75 to 88% common dandelion control. Overall weed control by all treatments ranged from 90 to 99% when observed on July 1, fifteen days following the postemergence (POST) treatment timing. On July 16, thirty days after POST treatments were applied, weed control remained good to excellent with the treatments and ranged from 87 to 99%. EPP applied Roundup PowerMAX followed by POST Roundup PowerMAX was an exception on July 16 where 78% common dandelion control was observed. (Dept. of Agronomy, Iowa State University, Ames).

Country: USA

Objectives:The purpose of this study was to evaluate early postemergence applied Corvus, 2,4-D

LV4, Roundup PowerMAX, Laudis, Cadet, Capreno and Ignite 280 in no-tillage corn.

Conclusions:Differences in corn stand were significant between several treatments. Differences were

attributable to variability in stand establishment and not herbicide treatment. Significant corn injury was observed on June 4, seven days after early postemergence (EPOST) treatments were applied. Injury ranged from 0 to 32%. Injury persisted with many of the treatments through the June 22 observation date. When observed on June 11, EPOST treatments gave good to excellent giant foxtail, velvetleaf, common waterhemp and common lambsquarters control ranging from 87 to 99%. Common dandelion control on June 11 with the EPOST treatments ranged from 75 to 98%. On June 22, EPOST treatments gave similar results in overall weed control as that observed on June 11.

EPOST applied Balance Flexx plus Capreno gave 82% giant foxtail and 89% common waterhemp control when observed on July 23, fifty-six days after application timing. Remaining treatments gave 90 to 99% control of these species. EPOST treatments gave 98 to 99% velvetleaf and 93 to 99% common lambsquarters control on July 23. Common lambsquarters control with EPOST applied Corvus plus Capreno was an exception where 82% control was observed. The range in common dandelion control on July 23 with EPOST treatments was considerable. EPOST Balance Flexx plus Capreno gave 43% common dandelion control, while Corvus plus 2,4-D LV4 and Corvus plus Ignite 280 gave 92% control.

applications of Corvus, Atrazine, Balance Flexx, Capreno, Roundup PowerMAX, Laudis and Ignite for crop phytotoxicity and weed control in corn.

Conclusions:Differences in corn stand between treatments were not significant. Early postemergence

(EPOST) applied Corvus plus Atrazine, Balance Flexx plus Atrazine and Capreno plus Roundup PowerMAX caused 5 to 20% corn injury when observed on June 11 and June 16, seven and twelve days after application, respectively. Giant foxtail, velvetleaf, common waterhemp and common lambsquarters control ranged from 96 to 99% on June 16 with the EPOST treatments. On June 16, zero days prior to mid-postemergence (MPOST) treatment timing, preemergence (PRE) treatments gave 85 to 93% giant foxtail, 87 to 99% velvetleaf, 90 to 99% common waterhemp and 93 to 99% common lambsquarters control.

MPOST applied treatments of Capreno plus Roundup PowerMAX and PRE applied Balance Flexx followed by MPOST Capreno plus Roundup PowerMAX caused 5 to 15% corn injury when observed on June 22 and July 1, six and fifteen days after application, respectively. Remaining MPOST treatments did not result in corn injury. PRE followed by MPOST treatments gave 98 to 99% overall weed control on July 1. On July 16, PRE, EPOST, MPOST and PRE plus MPOST treatments continued to provide 90% or higher weed control. An exception to this was PRE applied Corvus plus Atrazine where 83% giant foxtail control was achieved. (Dept. of Agronomy, Iowa State University, Ames).

Objectives:The purpose of this study was to evaluate two-pass programs in corn for crop

phytotoxicity and weed control.


control. These differences were attributable to variability in stand establishment and not herbicide treatment. Preemergence (PRE) applied treatments did not cause corn injury when observed on June 11, zero days prior to postemergence (POST) application timing. PRE treatments provided 82 to 95% giant foxtail, 43 to 98% velvetleaf, 94 to 99% common waterhemp and 83 to 99% common lambsquarters control on June 11.

POST applied Halex GT caused 5 to 8% corn injury when observed on June 16, 22 and July 9. No corn injury was observed from the remaining POST treatments. On July 9, PRE plus POST treatments provided 99% control overall. Treatments continued to provide at least 94% weed control on August 12 and September 28. Few significant differences in corn yield between treatments were determined. Herbicide treatment corn yields ranged from 165 to 190 bu/A.

not caused by the herbicide treatment, but rather due to variability in stand establishment. Treatments exhibited excellent crop safety on all observation dates. Excellent giant foxtail, velvetleaf and common waterhemp control was achieved by the treatments when observed on June 4, 22 and July 16. Weed control from the treatments ranged from 93 to 99% on these dates. Late-season weed control observations made on September 28 demonstrated continued good to excellent weed control by the treatments ranging from 88 to 99%. No significant differences in corn yields between the herbicide treatments or the untreated control were determined. Treatment corn yields ranged from 167 to 183 bu/A.

corn for phytotoxicity, weed control and yield.


determined. No crop injury was observed from the preemergence (PRE) applied treatments when observed on June 11, zero days prior to the postemergence (POST) application timing. PRE treatments gave 96 to 99% giant foxtail and common waterhemp control on June 11. Velvetleaf control was 92% and 93% with PRE applied Lexar and Lumax, while the remainder of the PRE treatments gave 22 to 68% control. Common lambsquarters control on June 11 ranged from 96 to 99% with most PRE treatments. However, PRE applied Dual II Magnum and Harness gave only 62 and 72% common lambsquarters control.

POST treatments caused 5 to 15% corn injury when observed on June 16, five days after application. Injury ranging from 0 to 8% continued to be observed from the POST treatments on June 22 and July 9. Weed populations were light in the study and the PRE followed by POST applied treatments gave 98 to 99% overall weed control when observed on June 22, July 9 and August 12. Corn yields ranged from 179 to 191 bu/A, and differences between the herbicide treatments and untreated control were not significant. (Dept. of Agronomy, Iowa State University, Ames).


















Fertilization included 140 lbs/A actual N applied as anhydrous ammonia. Crop residue on the soil surface was 30 to 40% at planting.

attributable to variability in stand establishment and not herbicide treatment. Postemergence (POST) applied treatments resulted in 0 to 15% corn injury when observed on June 16, 22 and July 9, five, eleven and twenty-eight days after application, respectively. Corn vigor was mostly excellent (excellent = 5) with the treatments when observed on June 22. Corn exhibited 60% and 99% disease incidence when observed on July 23 and August 12, respectively. Corn diseases included common rust and gray leaf spot. On July 23 and August 12, disease severity present on corn leaves ranged from 2 to 6% and 23 to 28%, respectively. Corn yields ranged from 183 to 219 bu/A. Significant differences in yield between several treatments were determined. (Dept. of Agronomy, Iowa State University, Ames).

Country: USA

Objectives:The purpose of this study was to evaluate soybean phytotoxicity, weed control and

yield from two and one-pass herbicide programs.

Conclusions:Early postemergence (EPOST) applied Durango plus FirstRate caused 10% soybean injury when

observed on June 22, six days after application. No soybean injury was observed on June 22 from the preemergence (PRE) applied treatments. PRE treatments gave 58 to 90% giant foxtail control, 90 to 99% velvetleaf, 57 to 95% common waterhemp and common lambsquarters and 45 to 53% Pennsylvania smartweed control on June 22. EPOST treatments afforded 96 to 99% weed control overall on June 22. An exception was Pennsylvania smartweed where EPOST treatments gave 80 to 88% control.

No soybean injury occurred from the early postemergence (EPOST)and postemergence (POST) applied treatments when observed on July 1, fifteen days and five days after application, respectively. On July 16, twenty-two days after POST application timing, PRE followed by POST treatments afforded 93 to 99% weed control. On July 16, seven days after the sequential postemergence (SPOST) application timing, 99% weed control was observed with the EPOST plus SPOST treatments. EPOST applied Roundup PowerMAX (not followed by SPOST) gave 57 to 88% weed control on July 16.

Late-season weed control observations made on August 12 showed that PRE plus POST and EPOST plus SPOST applied treatments continued to provide good to excellent weed control, ranging from 88 to 99%. The single EPOST application of Roundup PowerMAX afforded 43 to 95% weed control. Herbicide treatment soybean yields ranged from 59 to 66 bu/A and most yields were significantly higher than the untreated control. (Dept. of Agronomy, Iowa State University, Ames).

Trial ID: NSC 2 Protocol ID: HDEB02A4-2010USLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate Flexstar GT, Resource, Cadet, Roundup

PowerMAX and Cobra applied postemergence in soybean for crop phytotoxicity and weed control.

Conclusions:Early postemergence (EPOST) applied Flexstar caused 25% soybean injury when observed on

June 22, six days after application. Mid-postemergence (MPOST) applied treatments caused 0 to 43% soybean injury on July 1, seven days after application. Except for Pennsylvania smartweed, weed control with EPOST and MPOST treatments was good to excellent on July 1 ranging from 93 to 99%. Pennsylvania smartweed control with the EPOST and MPSOST treatments ranged from 82 to 98% on July 1.

Soybean injury was observed from the EPOST and MPOST treatments on July 16 and 23, twenty-two and twenty-nine days after MPOST application timing, respectively. MPOST Cobra exhibited 2 to 13% soybean injury on these dates, while EPOST Flexstar followed by late-postemergence (LPOST) applied Flexstar exhibited 10 to 17% injury. EPOST, MPOST and late-postemergence (LPOST) applied treatments gave 93 to 99% giant foxtail, common lambsquarters and Pennsylvania smartweed control when observed on July 23. Velvetleaf and common waterhemp control on July 23 with the same treatments ranged from 83 to 99% and 67 t 99%, respectively. Soybean yields ranged from 50 to 70 bu/A. All herbicide treatment yields were significantly higher than the untreated control. Significant differences in soybean yield between herbicide treatments were also determined.

Trial ID: NSC 3 Protocol ID: HCNN02A4-2010USLocation: Ames Study Director: Owen/Lux/Franzenburg/Grossnickle







Country: USA

Objectives:The purpose of this study was to evaluate two and one-pass weed management programs in

soybean for crop phytotoxicity, weed control and yield.

Conclusions:No soybean injury occurred from the preemergence (PRE) applied treatments when observed on

May 31, twelve days after application. Prefix applied early postemergence (EPOST) resulted in 32% soybean injury on June 22, six days after application. Preemergence (PRE) applied treatments gave 70 to 90% giant foxtail, 53 to96% velvetleaf, 73 to 95% common waterhemp, 57 to 73% common lambsquarters and 38 to 60% Pennsylvania smartweed control on June 22.

Mid-postemergence (MPOST) applied Flexstar plus Touchdown Total (following PRE applied Boundary) caused 20% soybean injury when observed on July 1, seven days after application. On July 9, 12% and 10% soybean injury was observed from EPOST applied Prefix plus Touchdown Total and MPOST applied Flexstar, respectively. No other treatment or application timing caused soybean injury on these dates. Except for EPOST Touchdown Total and MON 63410 plus Roundup PowerMAX, overall weed control on July 9 was 92% or higher with the various treatments and application timings.

No late-season soybean injury was evident from the treatments when observed on August 12. Treatments gave 90% or higher weed control on August 12. Exceptions to this were PRE applied Boundary plus MPOST Touchdown Total, MPOST Touchdown Total and PRE Optill plus MPOST Roundup PowerMAX which gave 70%, 83% and 57% common waterhemp control, respectively. Herbicide treatment soybean yields ranged from 57 to 62 bu/A and yields were significantly higher than the untreated control. No significant differences in soybean yield between the herbicide treatments were determined. (Dept. of Agronomy, Iowa State University, Ames).

Trial LocationCity: Belmond


Country: USA United States

Objectives:The purpose of this study was to evaluate the giant ragweed population for possible

resistance to various herbicide mechanisms of action.

Conclusions:Preemergence (PRE) treatments of Sharpen and Authority Assist provided 96% and 80% giant

ragweed control, respectively, when observed on June 3 and 10. Sharpen continued to provide 87 to 96% giant ragweed control on the remainder of the observation dates, while Authority Assist provided 23% control. Valor SX and Fierce did not provide acceptable giant ragweed control (0 to 30%) on any of the observation dates.

Postemergence (POST) applied Sharpen, Flexstar GT and Cobra provided 91% and higher giant ragweed control when observed on June 10, 17 and 24. POST applied Pursuit provided 18% giant ragweed control on these dates, while Roundup PowerMAX applied at 48 and 96 fl oz/A provided 55 to 57% and 70% control, respectively. On July 6, Sharpen, Flexstar GT and Cobra continued to provide 80% and higher giant ragweed control. Pursuit provided 12% and Roundup PowerMAX 55 to 68% giant ragweed control on July 6.

Trial LocationCity: Hartley



Objectives:The purpose of this study was to evaluate the common waterhemp population for possible


Conclusions:Sharpen, Flexstar GT, and Cobra provided 91 to 94% common waterhemp control on June 22 and

29. On July 7 and 13, control had declined with these treatments and ranged from 76 to 84%. Common waterhemp control with Roundup PowerMAX applied at 48 and 96 fl oz/A was 66 to 70% on the observation dates. The 96 fl oz/A Roundup PowerMAX application rate did not significantly increase common waterhemp control compared with the 48 fl oz/A rate. Pursuit provided no common waterhemp control on any of the observation dates. (Dept. of Agronomy, Iowa State University, Ames).

Conclusions:Common waterhemp control with the preemergence (PRE) treatments was poor to good and

ranged from 62 to 99% on June 3 and 10. On June 10, postemergence (POST) applied Sharpen, Flexstar GT and Cobra gave 78 to 94% common waterhemp control. Remaining POST treatments, including Roundup PowerMAX, gave 15 to 58% common waterhemp control.

On July 1, PRE applied Valor SX, Authority Assist and Fierce gave 87 to 98% common waterhemp control. However, 50% control was observed with PRE applied Sharpen. POST treatments of Sharpen, Flexstar GT and Cobra gave 73, 88, and 90% common waterhemp control, respectively, on July 1. Common waterhemp control ranged from 0 to 57% on July 1 with POST applied Pursuit and Roundup PowerMAX. (Dept. of Agronomy, Iowa State University, Ames).

Conclusions:Pursuit did not control common waterhemp on any of the observation dates. On June 13, 21,

28, July 6 and 14, common waterhemp control with Sharpen applied alone, ranged from 45 to 48% and 42 to 53% with Cobra. Flexstar GT, a pre-packaged mixture of fomesafen and glyphosate, and Roundup PowerMAX gave 93 to 96% and 96 to 99% common waterhemp control, respectively. Valor SX, Authority Assist and Fierce, all in tank-mixture with Roundup PowerMAX, gave 85 to 99% common waterhemp control, while Sharpen plus Roundup PowerMAX gave 52 to 95% control.
