Trial Comments

The "Pest Stage Majority" row on "Assessment Data" pages describes average weed heights or crop stage in treated plots.Wolly cupgrass (ERBVI) pressure in the trial was quite variable, and some giant foxtail was also present.

Missing data estimates are included in columns:Average=18Could not calculate LSD (% mean diff) for columns 1,2,3,5,11 because error mean square = 0.

Iowa State UniversityEarly preplant and postemergence herbicide programs in no-tillage corn, Ames, IA, 2017.

Trial ID: ACN2 Location: Ames Trial Year: 2017Protocol ID: Ames Corn NT 2017 Investigator: Micheal Owen









Objectives:The purpose of this study was to evaluate efficacy and selectivity for herbicides applied early preplant or postemergence in

no-tillage corn.




















Field Prep./Maintenance:The study area was left un-tilled since the 2015 cropping season. Fertilization included 21-70-120-17.5-1.75 lbs. of N-P-K-S-

Zn, respectively, applied as dry fertilizer in the fall, 2016. In the spring, 2017, 180 lbs/A actual N was applied as urea. Soil tests indicated soil fertility to be optimum for all nutrients. Crop residue on the soil surface was 65% at planting.

Trial ID: ACS1 Location: Ames Trial Year: 2017Protocol ID: WHLCorH3 Investigator: Micheal Owen









Objectives:The purpose of this study was to evaluate Acuron and competitor herbicides for burndown of early emerging annual weeds

and to compare full and split-rate Acuron application rates.






Pest DescriptionPest 1 Type: W Code: SETFA Setaria faberi

Common Name: Giant foxtail

Pest 2 Type: W Code: AMATA Amaranthus tamariscinusCommon Name: Common waterhemp







Field Prep./Maintenance:Fertilization included 21-70-120-17.5-1.75 of N-P-K-S-Zn, respectively, applied as dry fertilizer in the fall, 2016. In the

spring, 2017, 180 lbs/A actual N was applied as urea. Soil tests indicated soil fertility to be optimum for all nutrients. The study area has been left un-tilled since the 2015 cropping season. Crop residue that remained on the soil surface at

planting was 65%.

Trial Comments

Pest density units described in the "Pest Stage at Each Application" section may be labeled as weed counts per square foot or weed counts per plot.

Velvetleaf seedlings emerged within the trial following postemergence treatments and was included in control ratings.

Could not calculate LSD (% mean diff) for columns 1,4,5,8,15,17,19,21,22,26,29,33 because error mean square = 0.

Trial Comments

The "Pest Stage Majority" row on "Assessment Data" pages describes average weed heights or crop stages in treated plots.

Corn injury appeared mostly as chlorosis and some necrosis.

Ivyleaf morningglory pressure was somewhat variable.

Could not calculate LSD (% mean diff) for columns 2,3,4,5,8,14,20 because error mean square = 0.

Trial Comments

The "Pest Stage Majority" row on "Assessment Data" pages describes average crop stage or weed heights in treated plots.Pest density units described in the "Pest Stage At Each Application" section may be labeled as weed counts per square foot

or weed counts per plot.The LPOST application for Treatment 13 was not applied.The July 6 rating was designated only for evaluating burndown control for POST applications.Weed control ratings on June 27 represent new emergence of ivyleaf morningglory. Treatment 13, however, includes

regrowth of common waterhemp.Corn in the first ten frames of the trial suffered from significant moisture stress; at the July 18 rating, corn leaves had turned

grey and maintained a curled appearance.Common cocklebur pressure was light and variable. Ivyleaf morningglory pressure was somewhat variable.

Could not calculate LSD (% mean diff) for columns 1,4,5,12,19,22,26,29,33 because error mean square = 0.

Trial Comments

The "Pest Stage Majority" row on "Assessment Data" pages describes average weed heights or crop stages in treated plots.

Corn injury observed on June 16 for Treatments. 5, 6 and 15 appeared mostly as necrosis with some chlorosis. Injury for Trt.13 appeared as leaning corn plants with some snapping.

Ivyleaf morningglory pressure was variable or heavier in some places than in others.

Could not calculate LSD (% mean diff) for columns 4 because error mean square = 0.

Trial Comments


Late emergence of weeds (especially ivyleaf morningglory) was included as part of weed control ratings for the August 2 evaluation.

Could not calculate LSD (% mean diff) for columns 1,2,3,7,8,9,13,14 because error mean square = 0.

Trial Comments

Preemergence applications did not appear to be applied to Treatments 5 & 8, and two reps of Treatments 12 & 14 were not applied (all reps were treated as missing data).

Burndown (BURNDN) and control (CONTRL) were taken as separate ratings on July 13 because no initial control rating was taken at 14 days after the postemergence (POST) application. "BURNDN" describes initial control, and "CONTRL" includes both burndown and residual control of weed emergence since the POST applications.

Crop injury for Treatment 11 appeared as necrotic speckling.

Crop injury that appeared on June 27 appeared as necrosis on upper corn leaf edges and chlorosis from the margins, inward.

July 8 evaluations describe burndown and residual control of weed emergence for Treatments 2 through 11 and only burndown for Treatments 12, 13 and 14. Control ratings are comprehensive for all treatments, thereafter.

Velvetleaf pressure was very light.

Missing data estimates are included in columns:Average=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23Could not calculate LSD (% mean diff) for columns 1,5,13,17 because error mean square = 0.

very uneven (up to two or three leaf stages apart), and preemergence herbicide activity was reduced and inconsistent. Dry weather delayed broadleaf weed emergence, and postemergence applications were delayed.

Trial Comments

Pest density units described in the "Pest Stage at Each Application" section were estimated as weed counts per square foot or weed counts per plot.


very uneven (up to two or three leaf stages apart), and preemergence herbicide activity was reduced and inconsistent. Dry weather delayed broadleaf weed emergence, and postemergence applications were delayed.On July 13, average ground cover in the untreated controls for giant foxtail, velvetleaf, common waterhemp and venice

mallow were 83, 3, 12 and 1%, respectively. Injury to soybean observed on July 13 appeared as Chlorosis, necrosis and leaf puckering.Venice mallow pressure was very light.

Trial Comments

Rainfall was very limited following planting; no rainfall occurred for approximately two weeks. Resulting soybean stand was very uneven (up to two or three leaf stages apart), and preemergence herbicide activity was reduced and inconsistent. Dry weather delayed broadleaf weed emergence, and postemergence applications were delayed.

scattered throughout plots and covered by the tractor and planter to establish volunteer corn.Rainfall was very limited following planting; no rainfall occurred for approximately two weeks. Resulting soybean stand was

very uneven (up to two or three leaf stages apart).Soybean injury observed for Treatments 4 & 5 may have been caused mostly by chemical contamination of spray equipment.

Symptoms appeared as severe chlorosis and stunting that normally may occur with HPPD chemical exposure to soybean.

Trial Comments

Weed control was evaluated for each the PRE application, the PRE plus Liberty mid-POST applications and the PRE plus Liberty mid-POST plus Liberty late POST applications for each plot.

Postemergence Liberty applications provided complete burndown for all treatments, including the untreated checks. Control ratings for herbicide treatments characterized weed emergence, as compared to the untreated checks. Untreated checks were given a default 0 control, though weed emergence occurred in check plots following the Liberty applications.

Rainfall was very limited following preemergence applications; no rainfall occurred for approximately two weeks, and resulting preemergence herbicide activity was reduced. The dry weather also delayed broadleaf weed emergence. These factorsmade residual control ratings difficult.

Common waterhemp was not evaluated for the PRE plus mid-POST plus late POST Liberty applications because waterhemp pressure was too low and no new emergence occurred that late in the season.

Missing data estimates are included in columns:Average=23Could not calculate LSD (% mean diff) for columns 2,4,8,9,15,17,18 because error mean square = 0.

Trial Comments

The POST (B) application of Engenia plus Roundup PowerMAX was applied to only the front half (20 ft.) of each plot. Weed control and yield data was collected from both halves of each plot (DA-A vs. DA-B) following the the POST application.

Rainfall was very limited following planting; no rainfall occurred for approximately two weeks. The resulting soybean stand was very uneven (up to two or three leaf stages apart), and preemergence herbicide activity was reduced and inconsistent. Additionally, the dry weather delayed broadleaf weed emergence.

Trial Comments


The "Pest Stage Majority" row on "Assessment Data" pages describes average crop stage or weed heights in treated plots.Rainfall was well below normal and weed emergence was somewhat delayed, occurring mostly in wheel tracks. Soybean

stand was also uneven because of dry planting conditions.

Trial Comments

The "Pest Stage Majority" row on "Assessment Data" pages describes average crop stage or weed heights in treated plots.Pest density units described in the "Pest Stage At Each Application" section may vary from weed counts per square foot to

weed counts per plot.Soybean in Treatments 6, 7 & 8 showed 20 percent injury caused by sprayer contamination with dicamba on July 13 and

July 24. Injury from contamination was not included in the data collection and analysis.Rainfall was very limited following the preemergence application timing; No rainfall occurred for approximately two weeks

following applications. Resulting herbicide activity was reduced and inconsistent. A soybean "canopy" evaluation was performed on July 24. On that date, the Xtend soybean were closer to canopy than the

Liberty Link soybean.

Trial Comments


very uneven (up to two or three leaf stages apart), and preemergence herbicide activity was reduced and inconsistent.Weed control ratings taken July 26 characterize new weed emergence as well as burndown.The second postemergence (POST) application timing was not needed nor applied, as weed control from the preemergence

(PRE) and early postemergence (EPOST) applications provided adequate weed control.

Trial Comments

Weed control evaluations on July 7 were 4 days after the POST application. However, ratings were for residual control by PRE applications and for burndown control by EPOST applications.

Rainfall was very limited following planting; no rainfall occurred for approximately two weeks. Resulting soybean stand was very uneven (up to two or three leaf stages apart), and preemergence herbicide activity was reduced and inconsistent.

Dry weather delayed broadleaf weed emergence, and postemergence applications were delayed.Pest density units described in the "Pest Stage at Each Application" section may be labeled as weed counts per square foot

or weed counts per plot.The "Pest Stage Majority" row on "Assessment Data" pages describes average weed heights or crop stage in treated plots.Common waterhemp pressure was very light in the trial area at approximately 5 plants per plot.

Missing data estimates are included in columns:Average=16Could not calculate LSD (% mean diff) for columns 1,6,9 because error mean square = 0.

Trial Comments

Common waterhemp in the trial has demonstrated resistance to glyphosate in the past several years.Green foxtail was the primary grass species present in the trial area. However, 30 to 40 percent of of the grass species were

actually fall panicum. Therefore, control of both species were represented under green foxtail in the assessment data headings.

The "Pest Stage Majority" row on "Assessment Data" pages describes average crop stage or weed heights in treated plots.Common lambsquarters pressure in the trial area was light.Common waterhemp ratings on July 11 include plants still slowly dying from growth regulator activity.

Trial Comments

The "Pest Stage Majority" row on "Assessment Data" pages describes average crop stage or weed heights in treated plots.Weed control ratings taken on July 28 were at soybean canopy closure. Some soybean injury with cupping symptoms was caused by dicamba applications from outside of the experiment and was

not included in the soybean injury ratings. On July 10, 19 days after the postemergence applicaton, affected plots included 201, 202, 203 and 204 with cupping injury of 15, 5, 30 and 35 percent, respectively. Plots nubered 301, 302, 303 and 304 sustained 5, 5, 15 and 35 percent injury, respectively.

Missing data estimates are included in columns:Average=4,5,8,9,11,12,14,15Could not calculate LSD (% mean diff) for columns 1,2,6,12,15 because error mean square = 0.

Trial Comments

The "Pest Stage Majority" row on "Assessment Data" pages describes average crop stage or weed heights in treated plots.On July 10, ratings for Trts. 12-14 describe burndown, and Trts. 3-11 describe residual control of emerged weeds in addition

to burndown control. All treatment ratings on July 25 describe residual control with burndown.

Missing data estimates are included in columns:Average=3,6,9,12,15,18Could not calculate LSD (% mean diff) for columns 1,7,13 because error mean square = 0.

Trial Comments

Soybean stand was uneven because of dry conditions following planting.

"CONTRO" ratings on May 29 refer to burndown of the weeds rather than residual control.

Could not calculate LSD (% mean diff) for columns 1,2,3,4,12,13,15,16,17,20,22,23,24 because error mean square = 0.

Trial Comments

The "Pest Stage Majority" row on "Assessment Data" pages describes average crop stage or weed heights in treated plots.Yellow foxtail was one of the grass species in the first rep. However, only giant foxtail control was evaluated. Yellow foxtail

was not effectively controlled in Treatments 6, 7 & 8.Rainfall was very limited following the preemergence application timing; No rainfall occurred for approximately two weeks

following applications. Resulting herbicide activity was reduced and inconsistent.

Common waterhemp at this site have demonstrated resistance PPO inhibiting herbicides.

Heavy rain occurred 2 hours following the POST application amounting to several tenths of an inch over a half hour period.The trial area had excellent waterhemp pressure. However, few emerged following preemergence treatments. Only several

plants per plot emerged prior to the postemergence application for some treatments.
