Annual grass control Apply Poast at the grass size and rate indicated in the fo/bNing tables. If a grass has been cut, apply Pout after the reglUNlh reaches the mini­rrum height (so there will be enough leaf area to absorb Poast) and belore it exceeds the maximum height indicated in the table. Applications should be made before alfalfa can0-pies over the grasses and interfere!. with spray coverage. Also, applica­tions made after an alfalfa cutting

mal nee<! to be timed to foiloN an irri­gation or a rainfall which will alloN the grasses to regrow to a treatable size. Some annual Qrasses are spring- and St.rnmer-gerlTllOating while clhers are faD- or winter-germinating. and the time they are actively growing and most susceptible to Poast may vary from area to area. Also some amuals germinate over a long period 01 time, and since control 01 sman grasses is desired. applications after each weed flush may be needed. As a general guideline, spray sprilg- and summer- ~minating grasses as early ir. the sea son as possible. Opti­rrx.mappicationtningmayoccur very early in the spring after initial green-up.

General Information Poast is a selective broad spectrum postemer£er.ce herbicide for control of annual and perennial grass weeds in alfalfa. Poast does not control sedges or broad leaf weeds. Poast may be applied to seeding or established alfalfa grown for hay. silage, green chop, direct grazing or for seed. Malfa at all stages of growtt. is toterantto Poar The effectiveness of Poast is dependent on the absorption and I'TlCNOO1ent of Poast throughout the plant. For this to occur there must be enougI1leaf surface area to absorb the heroicide and the grass must be actively growing to move or trans­locate Poast to the roots and buds. Any stress conditions that slow the growth of the grass may decrease control or reduce the speed of con­trol. These stress conditions may include mowing, lack of moisture, herbicide injury, mechanical injury or cold temperatures.

Control symptom.: Poast rapidly enters the plant thIOugh the foliage and translocates ~ the Plant. Control symptoms exhibited by the grass plant progress from a slowing or stopping of growth (generally within 2 days), to reddening of the foliage, and to leaf tip burn. Subse­quently, burn-back of the foliage occurs. These symptoms will gener­ally be observed within three weeks, depending on environmental conditions.

Application Information' Apply Poast to actively growing grasses when they are at the proper growth stage as specified by the Recommendations for grass control. Thorough coverage of the grass foli­age is essential. This is because the effectiveness of Poast is aependent on the absorption and movement of Poast throughout the plant. Do not make applications to grasses under stress, such as stress due to lack of moisture, herbicide injury, mechanical injury or cold tempera­tures, since unsatisfactory control will probably result.

Broadcast aPPlication Nozzle type: t!'or broadcast applica­tion use standard high pressure pes­ticide hollow cone or flat fan nozzles, Do not use flood or whirl chamber nozzles.

For vegeta­ble oil concentrates, it has been observed that highly refined vege­table Oils are more satis:actory than unrefined vegetable oils. For addi­tional information see Jar test for estimating suitability of oil con­centrate belov.·. Rate of oil concentrate: Ground application-2 pints/acre.

Jar test for estimating suitability of oil concentrate 1. Water supply: Use only water

from intended source and at the . source temperature.

2. Amount 01 water in jar: For 20 galsJA spray volume use 3'1.3 cups (800 ml) of water For 10 galsJA spray volume use 1 % cups (400 ml) of water For 5 gals.lA spray volume use 0/6 cups (200 ml) of water For other spray volumes, adjust proportiona:ely to above.

3. Amount of herbicide and 011 concentrate to add: Add herbi­cide and Dash or oil concentrate at the rate of 1 teaspoon (5 ml) for each pint recommended label rate.

4. Add components in following sequence, gently mixing between component add;tions: 1. UAN solution or ammonium

sulfate (if used). 2. Dash Clr oil c:Jncentrate. 3. Poast.

5. Cap jar, invert 10 cycles, let stand for 15 mi,lutes, evaluate.

6. Evaluation: An ideal tank mix combination will be uniform; thus, the suitability of the oil concentr<:te is questionable if any of the follow­ing are observed: Free oil at the surface - film or globules. Flocculation - fine particles which may be suspended iOl the liquid or found a, a precipitated layer at the bottom of the jar Clabbering - thickening texture (coagulated) resembling yogurt or a r.urd-like texture, such as that of coltage cheese.

13 ~ ~ 3 Addition of UAN solution (urea " ammonium nitrate solution) or ammonium sulfate (AMS)·· UAN solution is commonly referred to as 28, 30, or 32% nitrogen, and is a water solution of urea and ammonium nitrate. Three quarts of liquid ammo­nium sulfate (8.0.0 analysis) may be substituted for 2'1.> Ibs. solid ammo-nium sulfate. For best control on volunteer corn, large (;rabgrass, wild oats, volunteer cereals, and quackgrass, add ammonium sulfate at 2Y2 Ibs. per acre plus Dash or oil concentrate or '12-1 gallon of UAN solution plus Dash or oil concentrate. In some areas the use of a nitrogen additive has improved control of rhizome johnsongrass. Consult your local BAS;- representative for the recommendation in your area. Always include Dash or oil concen­trate with the UAN solution or ammo-nium sulfate when applying Poast. Since most nitrogen solutions are mildly corrosive to galvanized, mild steel and brass spray equipment, be sure to rinse the entire spray system with water after use.

Note about ammonium sulfate It is important to use high quality ammonit;m sulfate to avoid plugging of siJlay nozzles. The ammonium SUl­fate must be readi;y soluble in water and contain no in30lubie materials. Local resc:Jrces of high quality fine feed graae ammonium sulfate nay be better than fertilizer grade. Low quality ammonium sulfate may con­tain material that will not readily dis­solve which could result in nozzle tip plugging. T:) determine Lluality. perform a jar test adding Y3 cup of ammonium sulfate to 1 gallJn of water and agitate for 1 minute. If undissolved sediment is observed, predissolve the amn1Qflium sulfate in water and Mer prior to addition to the spray tank. If amn1Qflium sulfate is completely dissolved in the spray tunk, add slowly with agitation. Add­ing too quickly may clog outlet lines Ensure that ammonium sulfate is completely dissolved in the spray tank before 'idding other products.

Tank mix of Poast with 2,4-D8 for grass and broadleaf weed control Use a tan" mix of Poash 2,4-00 for the control of mixed populations of grasses and broad leaf weeds listed as susceptible on the two product labels Prepare the tank mixture by adding 2.4-DB to half the !rral volum'? of water with agltalion running The"l

add Poast'~ herbicide and then the oil concentrate and bring mixture to final volume Agitation must be con­tinuous from time of mixing through spraying. Include 2, 4-0B as a tank mix with Poast, according to rates recommended on the individual product labels. 2,4-0B formulations include Butoxone'" herbicide (175 Ibs.lgal.); Butoxone Ester (2.0 Ibs.l gal.); Butyrac'" 200 herbicide (2.0 Ibs.lgal.); Butyrac Ester (2.0 Ibs.lgal.). Some leaf yellowing and burning of the al!alfa may occur with this tank mixture. Use of 2,4-08 ester formu­lations may increase the severity of leaf injury. Additionally, in established alfalfa, 2,4-0B alone may cause twist­ing of stems and malformation of leaves. (Refer to 2,4-08 labet.) Alfalfa plants will generally outgrow these temporary leaf injuries. Do not add Dash- spray adjuvant, UAN solution or arrrnoniurn sulfate to a Pf-.-ast plus 2,4-0B tank mixture. Do not apply Poast and 2,4-0B as a tank mix unless all feeding, grazing and harvesting restrictions on the 2,4-0B label can be observed. Observe all cautions and limitations on the label of both products. The most restrictive labeling applies in tank mixes.

Alfalfa Recommendations for grass control • Apply to actively growing grasses at

the sizes indicated below. • Always follow recommendations

given in the Application informa­tion section.

• Always adjust spray pressure, spray volume and height of spray boom to ensure penetration of plant canopy and thorough coverage of grasses to be controlled.

• In irrigated areas, apply Poast 2 to 4 days after an irrigation.

• Always add 2 pints of Dash or 011 concentrate per ac;-e,

Annual grass control Apply Poast at ttl(, grass size and rate ind;~ated in the following tables. If a grass has been cut, apply Poast after the regrowth reaches the mini­mum height (so there will be enough leaf area to absorb Poast) and before it exceeds the maximum height indicated in the table. Applications she: lid be made before alfalfa cano­pies aver the grasses and interferes with spray coverage. Also, applica­tions made after an alfalfa cutting

may need to be timed to follow an irri­gation or a rainf<:11 which will allow the grasses to regrow to a treatable size. Some annual grasses are spring- and summer-germinating while others are fall- or winter-germinating, and the time they are actively growing and most susceptible to Poast may vary from area to area. Also some annuals germinate o.tef a long period of time, and since control of small grasses is desired, applications after each weed flush may be needed. As a general guideline, spray spring- and summer-germinating grasses as earty in the season as possible. Opti­mum application t; ·-19 may occur very early in the spring after ir.itial green-up. Spray fall- or winter-germi­nating weeds in the fall soon after they begin growing but before any killing frosts. This is because the weeds are more susceptible to Poaat when they begin growth and co ltrol is more complete. However, late fall applications may be le~ effective due to tmvironmental changes, such as frosts, or due to the on-set of flowering.

Inter-seeded oats Oats inter -seeded with alfalfa may be killed back with an application of Poast. Their removal allows the seeding alfalfa to grow with less com­petition. This application should be made before the oats get too large. Applications made in the boot stage or later will not be as effective as when an application is made on young oats.

Perennial grass control Poast effectively controls or sup­presses perennial grasses such as bermudagrass, johnsongrass, quackgrass, wirestem muhly and perennial ryegrass. However, their growth characteristics are such that they are more difficult to control than annual grasses, especially in a per­ennial crop such as established alfalfa. A program consisting of repeated applications is usually necessary for best results.

Mowing Best control of annual grasses can be achieved if applications are made before grass weeds are mowed off. Once a grass is mowed it L>ecomeS tougher to control. This is because much of the leaf surface may be removed by the mowing and the grass is put under stress. Because of this, a lower rate is recommended for foxtail control hoe table for Western ar>d Mountair _. des) before the second cutting. In southern areas without a killing frost, some annuals slJrvive through the winter

1

I L( til . .23 These grasses can form large lrowns which contain many viable buds. A large crown, even if it is that of an annual gras:" :T:ay require repeated applications for control and depend­ing on the species and size of th€l crown, control may not be complete.

Irrigation Irrigation practices can be very criti­caito the successful use of Poast. This is because an irrigation may be necessary to sta, t the grass weeds growing again. Generally, an applica­tion 2-4 days after an irrigation is most effective. This is because: 1) grasses resume active growth, 2) they have less of a chance to grow too large and 3) by waiting later, the aHalfa begins to canopy and inter­feres with 'lPray coverage. Irrigation shortly after (within 2 days) an appli­cation has been effective, but more consistent grass control is obtained when the ;rrigation was made before the application. in large fields, it may take several days for water to move across a field. The grasses should 11-11 be allowed to grow too large on the side of the field irrigated first while waiting for the entire field to be irrigated. In these sit­uations the field should be sprayed in segments, following the irrigation, to obtain best results. The most econc."T1ic way of controlling perennial grasses is to do so In the yp.ar of ~tand establishment before rhizomes or stolons become large and difficult to kill. The field should be disked before seeding to thoroughly fragment rhizomes or stolons. In summer and fall seedings, cool season grasses (quackgrass, wire­stem muhly, perennial ryegrass) can become very competitive under cool fall conditions. Fall applications of Poast will reduce late season grass growth and limit the ability of grasses to accumulate nutrient reserves in roots and rhizomes. In established stands it is important to begin applicati'1ll in the spring when conditions favor active growth and before weed storage tissues have increased their nutrient reserves. Additional applications should be made on an~·aril~ regrowth in la~' tl J\t~19S. • •

Restrictions and limitations foralfaHa Do not make applications to grasses under stress, such as stress due to lack of moisture, herbicide injury, me .hanical injury or cold tempera­ture~, since unsatisfactory control will probably result. Do not apply if rainfall is expected within one hour following application as grass control will probably be unsatisfactory. Do not apply to alfalfa under stress, such as stress due to insect damage, lack of moisture, herbicide injury, mechanical injury or cold tempera­tures since leaf speckling or yellowing will probably resutt, Do not apply Poast3 herbicide within 7 days of grazing. feeding. or cutting for (undried) forage. or within 20 days of cutting alfalfa for (dry) hay. Do not apply Pout and 2,4-08 as a tank mix unless the 6O-day feeding. g·azing and harvesting restrictions on the 2,4-0B label can be observed. Do not mix or apply Poast with any other pesticide. additive. or fertilizer except as specifically recommended on thiS labeling. Do not apply more than a total of 6V2 pints of Poast per acre in one season. Poast may be applied to alfaifa by ground and air application equipment Do not apply Poast through any type of Irrigation equipment.
