Product Information 

Aceto Mepiquat Chloride 4.2% PGR is a plant regulator for use on cotton. This product is use in a foliar application to help 

manage the cotton plant for short season production. This allows the grower to reduce the risk of yield loss and quality loss 

due to delayed and prolonged harvest cycles. The use ofthis product also offers additional benefits including less boll rot, 

reduction in plant height with more open canopy, increased early boll retention and/or large bolls, improved defoliation with 

less trash, lower ginning costs, better harvest efficiency and richer dark green leaf color. Most of these benefits may 

fuvorably enhance the yield potential of the cotton plant. 

Spray Coverage 

Unifurm, thorough spray coverage of cotton fuliage is important to achieve consistent performance. Calibrate application 

equipment according to manufacturer's specifications. Use nozzle type arrangements that provide optimum spray 

distribution and maximum coverage. 

In most applications, water is the preferred diluent, however oil fur ultra low volume (ULV) aerial applications is allowed in 

the following states:

Water as Diluent: Use 2 gallons of spray solution per acre in all states except California. In California, use a minimum of 5 

gallons per acre. 

AIR Application 

Water as Diluent: Use a minimum of2 gallons of water per acre in all states except Califurnia. In California, use a 

minimum of 5 gallons per acre. 

Oil as Diluent: Use a minimum ofl quart of oil per acre. When using oil as a diluent, the oil concentrate must contain 

either a petroleum or vegetable oil base and must meet all of the following criteria: 

Be nonphytotoxic 

Contain only EPA-exempt ingredients 

Provide good mixing quality in the jar test 

Be successful in local experience 

The exact composition of suitable products will vary; however, vegetable and petroleum oil concentrates should contain 

emulsifies to provide good mixing quality. Ifthe oil does not contain an emulsifier, onernust be added during mixing at a 

volume equal to 3% of the final volume of the mixing tank. Do not apply this product by ULV without using emulsifiers.

Mixing 

Clean sprayer parts immediately after using this product by thoroughly flushing with water. 

This product mixes readily with water. Mix spray solutions of this product as follows: 

Fill the mixing or spray tank with the required amount of water. 

Add the specified amount of this product near the end of the filling process and mix welL 

• Use caution to avoid siphoning back into the carrier source. Use approved anti-back-siphoning devices required by state 

or local regulations. 

During mixing and application, foaming of the spray solution may occur. To prevent or minimize foam, avoid the use of 

mechanical agitators, terminate by-pass and return lines at the bottom of the tank and, if needed, use an approved antifoam or defuaming agent. 

Tank Mixing Procedure: 

Always predetermine the compatibility of labeled tank mixtures of this product with water or oil diluent by mixing small 

proportional quantities in advance. Use a small container and mix ail components in a small amount, usually 0.5 to Iqt. of 

spray. Combine all products in the same ratio and order of addition as in the proposed spray mixture. Observe the mixture for 

indication of incompatibility which usual occurs in 10 to 30 minutes after mixing. Ifincompatibility is observed, try changing 

the order of addition of the components. The guideline on tank mixture partners is driven by formulation type. Start with 

wettable powders (WP's) including water soluble bags (WSB's), water dispersible granules (WDG's), dry flowables (DF), 

suspension concentrated (SC's) or flowable (F's), all with very good agitation to ensure a homogenous suspension. Next 

follow with water miscible concentrates and emulsifiable concentrates (EC's) before adding additives. After agitation, there 

must be a homogeneous suspension. Let the final tank mixture stand and observe for any rapid settling or floating of 

components. If any indications of physical incompatibility develop, do not use this mixture for spraying. 

Spray Equipment Cleanout 

The mix tank and spray equipment cleanout is an important stewardship activity to avoid injury to desirable crops. It is 

important to clean all mixing and spraying equipment immediately after use and before using pesticide products including 

this product. To clean the spraying equipment, follow the procedure outlined below: 

• Completely drain the mix tank and/or sprayer, and then wash thoroughly the tank, sprayer, boom and n02'Zles with 

clean water. Drain the system again. 

• Fill the mixing or spray tank halffull with clean water and add domestic ammonium, normally a 3% solution, at a 

dilution rate of 1% vol/vol ammonium or I gallon per 100 gallons ofrinsate. 

• Completely fill the tank(s) with additional clean water. Agitate and recirculate and flush out the boom and hoses. Let 

the system run for 10 - 15 minutes. Drain the system completely. 

• Remove nozzles and screens and dislodge any visible solid material. Then soak them in a I % vol/vol ammonium 

solution. Inspect the nozzles and screen and remove any visual residues. 

• Repeat the above procedure for a second time. 

• Flush the mix tank and/or sprayer, boom and hoses with clean water. Drain the system again and inspect for any 

visible residues. If present, repeat the cleaning cycle again. 

• If the rinsate cannot be disposed of by use acrording to label instructions, contact your State Pesticide 0$, •• 

Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional O'tnCf) fur 

guidance. ; , , ,

Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment and 

weather related factors detennine the potential for spray drift. The applicator and the grower are responsible for t9'l!5i:-;J~ing 

all these factors when making decisions. The following drift management requirements must be followed to avoi'd off-target 

drift movement from aerial applications to agricultural field crops. These requirements do not apply to furestry applications,

1. The distance of the outer most nozzles on the boom must not exceed % the length of the wingspan or rotor. 

2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more then 45 

degrees. Where states have more stringent regulations, they must be observed. 

The applicator should be familiar with and take into account the information covered in the publication titled A Summarv of 

Aerial Application Studies by the Spray Drift Task Force. 

The importance of spray droplet size: 

The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the 

largest droplels that provide sufficient coverage and controL Applying larger droplets reduces drift potential but may not 

prevent drift if applications are made improperly or under unfuvorable environmental conditions (see the following "Wind", 

"Temperature and Humidity" and "Temperature Inversion" sections ofthis label). 

Controlling droplet size: 

• Volume- Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher flow rates 

producer larger droplets. Use a minimum of5 gallons of water per acre. Increase water volume to at least 10 

gallons of water per acre. Increase water volume to at least 10 gallons of water per acre if grass foliage or crop 

canopy is dense. 

• Pressure - Use the lower spray pressures listed for the nozzle. Higher pressure reduces droplet size and does not 

improve canopy penetration. When higher flow rates are needed, use higher flow rate nozzles instead of increasing 

pressure. Use up to 40 psi. 

• Number of nozzles - Use the minimwn number of nozzles that provide unifurm coverage. 

• Nozzle orientation - Orienting nozzles so the spray stream is released backwards, parallel to air stream will produce 

larger droplets than other orientations. Significant deflection from the horizontal will reduce droplet size and 

increase drift potential. 

• Nozzle type- Use a nozzle type that is designed for the intended application. With most nozzle types, narrower 

spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back 

produce larger droplets than other nozzle types. Use only diaphragm-type nozzles that produce fan spray patter 

Boom Length: For some use patterns, reducing: the effective boom length to leSS than Yo of the wingspan or rotor lengthmay 

future reduce drift without reducing swath width. 

Application Height: Applications should be made at a height greater than 10 feet above the top of the largest plants. Making 

applications at the lowest height is safe reduces exposure to droplets to evaporation and wind. 

Swath adjustment - When applications are made with a cross-wind, the swath will be displaced downwind. Therefore, on the 

up and downwind edges ofthe field, the applicators must compensate for this displacement by adjusting the path of the 

aircraft upwind. Swath adjustment distances should increase drift potential (wind speed, droplet size, etc.) 

Wind - Drift potential is the lowest between wind speeds of2 to 10 mph. However, many factors including droplet size and 

equipment type detennine drift potential at any given speed. Application must be avoided when wind speeds are below 2 

mph due to variable wind direction and high inversion potential. Do not apply this product by aircraft when wind is blowing 

more than 10 mph. NOTE: Local terrain can influence wind patterns. Applicators must be familiar with local wiPP,natterns 

and how they affect drift. ' " > , ' 

, > , , 

Temperature and humidity- When making applications in low relative hwnidity set up equipment to produce la';l3cr,droplets 

to C{)mpensate fur evaporation. Droplet evaporation is most severe when C{)nditions are both hot ap~)clry., 

Temperature Inversions - Do not apply during a temperature inversion because drift potential is high, :r~~peratU;~:: ' 

inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrato/! 'Cloud. 'Thisdood 

can move in unpredictable directions due to the light variable air currents that are common during ;py~~~ion. Tempern.t~re 

inversions are characterized by increasing temperatures which altitude and are common on nights ,'hl} limited cloud -cover

Sensitive areaS: 

Use pesticides product adjacent to sensitive areas only when there is minimal potential for drift or off target movement, e.g. 

wind is blowing away from non-target crops, residential areas, bodies of water, known habits fur threatened or endangered 

species, etc. Do not apply this product by air ifsensitive species are within 200 feetdo\VIl.wind. 

APPLICATION INSTRUCTIONS 

Early Application 

On both Short-staple and Pima cotton, the grower has the option of low rate multiple applications (see Table I) or higher, less 

frequent applications (see Table II) which greatly facilitates his management flexibility. The multiple application option 

gives the producer the ability to discontinue usage of this product if any significant stresses occur after an earlier application. 

In such a case, the total quantity of this product used over a season may be reduced. If stress is relieved, the grower has the 

option of continuing treatments with this product. In addition, the rate and timing ranges indicated in the Application Rates 

and Timing Tables allow the grower to tailor his usage of this product to the degree of vegetative vigor in a given field. In 

areas where insecticides, miticides or foliar fertilizers are frequently applied, the timJngs are such that tank mixing is often 

possible. (See Cotton Restrictions and Precautions) 

Fields should be carefully scouted and this product should not be applied if plants are under severe stress from weather 

fuctors, mite, insect or nematode damage, disease stress, herbicide injury, or fertility stress. In the absence of these stresses, 

up to 5 low-rate multiple applications can be made each season. After the first application, (at matchhead square in the 

absence of stress), the rate and timing of subsequent applications will depend on vegelative vigor. Under good growing 

conditions, additional treatments should be at 7-14 day intervals. However, ifnew growth at any time is excessive, higher 

rates of this product can be used. 

If significant loss of squares or young bolls has occurred early due to insect pressure or other stresses, but now these stresses 

have been alleviated the need for this product is increased - excess vegetative growth is likely because of poor boil load. 

Late Season Application 

Late application of this product (approximately during the fourth to sixth week of blooming) can provide certain benefits to 

cotton. However, it should not and does not substitute for early season use - the time ofthe greatest benefit from the use of 

this product. Late season application can lead to one or more ofthe following: 

• Reduction in late season vegetative growth or regrowth after cutout of defoliation 

• More complete and manageable cutout 

• Better defoliation 

• Early maturity 

• Reduction in trash 

• Lower ginning cost 

Some of these effects may favorably influence the yield potential and fiber quality. A late season application of this product 

should be applied only if fields are not drought or nutrient stressed; that is, those fields likely to experience additional 

vegetative growth or regrowth. However, fields that are very rank and extremely vigorous due to a combination of poor boli 

load and excellent growing conditions may not respond as much as desired to late season applications at the sspecified rates. 

Time for Late Season Applications > >' • 

On fields where cotton cuts outs and tben starts regrowth: Apply when regrowth begins, as evidenced by new lft2Nes in 

the terminal and stem elongation. This application time is often, but not always, 5-6 weeks after first bloom. ,> , , 

On fields where cotton never completely cuts out: Apply this product where there are 4-6 nodes above the wJ:oj~;f!ower 

(NA WF). Measure NA WF by counting the number of main stem nodes from the first position whits! MI)I'J') (the ciosC'>t to the 

mainstem) to the terminal. Count the node with the first position white bloom as zero and the last l!ode'in'>J:he terrr.i.nnl;which 

is counted, should have leafat least the size ofa quarter. Generally, the NA WF first reaches 4-6 nr;~f) <j'Jring the' fuurth'to

Product Information 

Aceto Mepiquat Chloride 4.2% PGR is a plant regulator for use on cotton. This product is use in a foliar application to help 

manage the cotton plant for short season production. This allows the grower to reduce the risk of yield loss and quality loss 

due to delayed and prolonged harvest cycles. The use ofthis product also offers additional benefits including less boll rot, 

reduction in plant height with more open canopy, increased early boll retention and/or large bolls, improved defoliation with 

less trash, lower ginning costs, better harvest efficiency and richer dark green leaf color. Most of these benefits may 

favorably enhance the yield potential ofthe cotton plant. 

Spray Coverage 

Uniform, thorough spray coverage of cotton foliage is important to achieve consistent performance. Calibrate application 

equipment according to manufacturer's specifications. Use nozzle type arrangements that provide optimum spray 

distribution and maximum coverage. 

In most applications, water is the preferred diluent, however oil for ultra low volume (ULV) aerial applications is allowed in

Mixing 

Clean sprayer parts immediately after using this product by thoroughly flushing with water. 

This product mixes readily with water. Mix spray solutions ofthis product as follows: 

Fi!! the mixing or spray tank with the required amount ofwater. 

Add the specified amount of this product near the end ofthe filling process and mix well. 

• Use caution to avoid siphoning back into the carrier source. Use approved anti-back-siphoning devices required by state 

or local regulations. 

During mixing and application, foaming of the spray solution may occur. To prevent or minimize foam, avoid the use of 

mechanical agitators, tenninate by-pass and return lines at the bottom ofthe tank and, ifneeded, use an approved antifoam or defoaming agent 

Tank Mixing Procedure: 

Always predetermine the compatibility of labeled tank mixtures of this product with water or oil diluent by mixing smaU 

proportional quantities in advance. Use a smaU container and mix aU components in a smaU amOlUlt, usually 0.5 to lqt of 

spray. Combine all products in the same ratio and order of addition as in the proposed spray mixture. Observe the mixture for 

indication of incompatibility which usual occurs in 10 to 30 minutes after mixing. Ifincompatibility is observed, try changing 

the order of addition of the components. The guideline on tank mixture partners is driven by formulation type. Start with 

wettable powders (WP's) including water soluble bags (WSB's), water dispersible granules (WDG's), dry f10wables (DF), 

suspension concentrated (SC's) or f10wable (F's), all with very good agitation to ensure a homogenous suspension. Next 

fo!!ow with water miscible concentrates and emulsifiable concentrates (EC's) before adding additives. After agitation, there 

must be a homogeneous suspension. Let the final tank mixture stand and observe for any rapid settling or floating of 

components. Ifany indications of physical incompatibility develop, do not use this mixture for spraying. 

Spray Equipment Cleanout 

The mix tank and spray equipment cleanout is an important stewardship activity to avoid injury to desirable crops. It is 

important to clean al! mixing and spraying equipment immediately after use and before using pesticide products including 

this product. To clean the spraying equipment, fo!!ow the procedure outlined below: 

• Completely drain the mix tank and/or sprayer, and then wash thoroughly the tank, sprayer, boom and nozzles with 

clean water. Drain the system again. 

• Fi!! the mixing or spray tank halffu!! with clean water and add domestic ammonium, normaUy a 3% solution, at a 

dilution rate of 1% vol/vol ammonium or 1 gallon per 100 gal!ons ofrinsate. 

• Completely fi!! the tank(s) with additional clean water. Agitate and recirculate and flush out the boom and hoses. Let 

the system run fur 10 -15 minutes. Drain the system completely. 

• Remove nozzles and screens and dislodge any visible solid material. Then soak them in a 1% vol/vol ammonium 

solution. fuspect the nozzles and screen and remove any visual residues. 

• Repeat the above procedure for a second time. 

• Flush the mix tank and/or sprayer, boom and hoses with clean water. Drain the system again and inspect for any 

visible residues. If present, repeat the cleaning cycle again.

1. The distance of the outer most nozzles on the boom must not exceed % the length ofthe wingspan or rotor. 

2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more then 45 

degrees. Where states have more stringent regulations, they must be observed. 

The applicator should be familiar with and take into account the information covered in the publication titled A Summary of 

Aerial Application Studies by the Spray Drift Task Force. 

The importance of spray droplet size: 

The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the 

largest droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential but may not 

prevent drift if applications are made improperly or under unfavorable environmental conditions (see the following "Wind", 

"Temperature and Humidity" and ''Temperature Inversion" sections of this label). 

Controlling droplet size: 

• Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher flow rates 

producer larger droplets. Use a minimum of 5 gallons of water per acre. Increase water volume to at least 10 

gallons of water per acre. Increase water vohune to at least 10 gallons of water per acre ifgrass foliage or crop 

canopy is dense. 

• Pressure - Use the lower spray pressures listed for the nozzle. Higher pressure reduces droplet size and does not 

improve canopy penetration. When higher flow rates are needed, use higher flow rate nozzles instead of increasing 

pressure. Use up to 40 psi. 

• Number of nozzles - Use the minimwn number of nozzles that provide uniform coverage. 

• Nozzle orientation - Orienting nozzles so the spray stream is released backwards, parallel to air stream will produce 

larger droplets than other orientations. Significant deflection from the horizontal wiIl reduce droplet size and 

increase drift potentiaL 

• Nozzle type- Use a nozzle type that is designed for the intended application. With most nozzle types, narrower 

spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back 

produce larger droplets than other nozzle types. Use only diaphragm-type nozzles that produce fan spray patter 

Boom Length: For some use patterns. reducing the effective boom length to less than % of the wingspan or rotor lengthmay 

future reduce drift without reducing swath width. 

Application Height: Applications should be made at a height greater than 10 feet above the top of the largest plants. Making 

applications at the lowest height is safe reduces exposure to droplets to evaporation and wind. 

Swath adjustment When applications are made with a cross-wind, the swath will be displaced downwind. Therefore, on the 

up and downwind edges of the field, the applicators must compensate for this displacement by adjusting the path of the 

aircraft upwind. Swath adjustment distances should increase drift potential (wind speed, droplet size, etc.) 

Wind - Drift potential is the lowest between wind speeds of2 to 10 mph. However, many factors including droplet size and 

equipment type determine drift potential at any given speed. Application must be avoided when wind speeds are below 2 

mph due to variable wind direction and high inversion potential. Do not apply this product by aircraft when wind is blowing 

more than 10 mph. NOTE: Local terrain can influence wind patterns. Applicators must be familiar with local w.iftd patterns 

and how they affect drift. ", > , , > > 

, 

Temperature and humidity When making applications in low relative humidity set up equipment to produce larger Ciroplets 

to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot a~a 'dry.: • , , , "" , 

Temperature Inversions - Do not apply during a temperature inversion because drift potential is higfi.~ Te:nperatu:e" > , 

inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. -This ~ioud 

can move in unpredictable directions due to the light variable air currents that are common during fu~~~sion. Temp~rature 

inversions are characterized by increasing temperatures which altitude and are common on nights Wi'th i~ited cloud ~over and light to no wind. They begin to form as the sun sets and often continue into the morning. Their presence Call oi! > ; , 

indicates by ground fug; however, iffog is not present, inversion can also be identified by the movement of smok,e fr01]1 a 

ground source or an aircraft smoke detector. Smoke that layers and moves laterally in a concentrated cloud (und~>lbWwind 

conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing.

species, etc. Do not apply this product by air if sensitive species are within 200 feet downwind. 

APPLICATION INSTRUcrIONS 

Early Application 

On both short-staple and Pima cotton, the grower has the option of low rate multiple applications (see Table I) or higher, less 

frequent applications (see Table II) which greatly facilitates his management flexibility. The multiple application optien 

gives the producer the ability to discontinue usage of this product ifany significant stresses occur after an earlier application. 

In such a case, the total quantity of this product used over a season may be reduced. If stress is relieved, the grower has the 

option of continuing treatments with this product. In addition, the rate and timing ranges indicated in the Application Rates 

and Timing Tables allow the grower to tailor his usage ofthis product to the degree of vegetative vigor in a given field. In 

areas where insecticides, miticides or foliar fertilizers are frequently applied, the timings are such that tank mixing is often 

possible. (See Cotton Restrictions and Precautions) 

Fields should be carefully scouted and this product should not be applied if plants are under severe stress from weather 

metors, mite, inseet or nematode damage, disease stress, herbicide injury, or fertility stress. In the absence ofthese stresses, 

up to 5 low-rate multiple applications can be made each season. After the first application, (at matchhead square in the 

absence of stress), the rate and timing of subsequent applications will depend on vegetative vigor. Under good growing 

conditions, additional treatments should be at 7-14 day intervals. However, ifnew growth at any time is excessive, higher 

rates ofthis product can be used. 

If significant loss of squares or young bolls has occurred early due to insect pressure or other stresses, but now these stresses 

have been alleviated the need for this product is increased - excess vegetative growth is likely because of poor boil load. 

Late Season Application 

Late application of this product (approximately during the fourth to sixth week of blooming) can provide certain benefits to 

cotton. However, it should not and does not substitute for early season use - the time of the greatest benefit from the use of 

this product. Late season application can lead to one or more of the following: 

• Reduction in late season vegetative growth or regrowth after cutout of defoliation 

• More complete and manageable cutout 

• Better defoliation 

• Early maturity 

• Reduction in trash 

• Lower ginning cost 

Some of these effects may fuvorably influence the yield potential and fiber quality. A late season application of this product 

should be applied only iffields are not drought or nutrient stressed; that is, those fields likely to experience additional 

vegetative growth or regrowth. However, fields that are very rank and extremely vigorous due to a combination of poor bo1i 

load and excellent growing conditions may not respond as much as desired to late season applications at the sspecified rates. 

Time for Late Season Applications 

On fields where cotton cuts outs and tbeu starts regrowtb: Apply when regrowth begins, as evidenced by ne~>leaves in 

the terminal and stem elongation. This application time is often, but not always, 5-6 weeks after first bloom. : ,> > 

On fields wbere cotton never completely cuts out: Apply this product where there are 4-6 nodes above the whit~ power 

(NA WF). Measure NA WF by counting the number of main stem nodes from the first position whije' 6loo(n (the cl0}ir~t to the 

mainstem)to the terminal. Count the node with the first position white bloom as zero and the last I1?1~ \l"\ the tel.'lJ}ipJiVwhich 

is counted, should have leaf at least the size of a quarter. Generally, the NA WF first reaches 4-6 not{.'S ,d,wing the fqurfll to 

sixth week of bloom. During this time, the NAWF should be decreasing about one node every 5-q 9Sl.,{s,- ifits 1'311J of' 

decrease is less, the plant is not cutting out soon enough (the crop is too vigorous). If the fifth week .)fbioom arrive;; and the 

NA WF is sti1i above 5-6, apply this product. " > , , , 

."" , 

Use Rate for Late Season Application 

Apply 8-24 fl. oz. of this product per acre. Use the lower rate on cotton with only moderate additional growth p6iehhiu', and 

the higher rate on fields likely to continue vigorous growth.

Acelo Mepiqual Chloride 4.2%PGR 

December 8, 2010 

Page 2 of9 
31

Aceto Mepiquat Chloride 4.2% PGR is a plant regulator for use on cotton. This product is use in a foliar application to help 

manage the cotton plant for short season production. This allows the grower to reduce the risk of yield loss and quality loss 

due to delayed and prolonged harvest cycles. The use of this product also offers additional benefits including less boll rot, 

reduction in plant height with more open canopy, increased early boll retention and/or large bolls, improved defoliation with 

less trash, lower ginning costs, better harvest efficiency and richer dark green leaf color. Nonnally most of these benefits 

favorably enhance the yield potential of the cotton plant. 

Spray Coverage 

Uniform, thorough spray coverage of cotton foliage is important to achieve consistent perfonnance. Calibrate application 

equipment according to manufacturer's specifications. Use nozzle type arrangements that provide optimum spray 

distribution and maximum coverage. 

In most applications, water is the preferred diluent, however oil for ultra low volume (ULV) aerial applications is allowed in 

the following states: 

Alabama 

Louisiana 

Oklahoma 

Spray Volume 

GROUND Application 

Arkansas 

Missouri 

South Carolina 

Florida 

Mississippi 

Tennessee 

Georgia 

North Carolina 

Texas 

Water as Diluent: Use2 gallons of spray solution per acre in all states except California. In California, use a minimum of5 

gallons per acre. 

AIR Application 

Water as Diluent: Use a minimum of2 gallons of water per acre in all states except California In California, use a 

minimum of 5 gallons per acre. 

Oil as Diluent: Use a minimum of 1 quart of oil per acre. When using oil as a diluent, the oil concentrate must contain 

either a petroleum or vegetable oil base and must meet all of the following criteria: 

Be nonphytotoxic 

Contain only EPA-exempt ingredients 

Provide good mixing quality in the jar test 

Be successful in local experience 

The exact composition of suitable products will vary; however, vegetable and petroleum oil concentrates should contain 

emulsifies to provide good mixing quality. If the oil does not contain an emulsifier, one must be added during missing at a 

volume equal to 3% of the fmal volume of the mixing tank. Do not apply this product ULV without using emulsifiers. 

Highly refined vegetable oils have proven more satisfactory than unrefined vegetable oils. For additional information see 

Tank Mixing Procedure. 

Additives 

If rain is anticipated within 8 hours, use a high quality, EPA exempt surfactant to make this product rainsafe after 4 hours.

Tank Mixing Proced ure: 

Always predetermine the compatibility oflabeled tank mixtures of this product with water or oil diluent by mixing small 

proportional quantities in advance. Use a small container and mix all components in a small amount, usually 0.5 to Iqt. of 

spray. Combine all products in the same ratio and order of addition as in the proposed spray mixture. Observe the mixture for 

indication of incompatibility which usual occurs in 10 to 30 minutes after mixing. If incompatibility is observed, try changing 

the order of addition of the components. The guideline on tank mixture partners is driven by formulation type. Start with 

wettable powders (WP's) including water soluble bags (WSB's), water dispersible granules (WDG's), dry flowables (DF), 

suspension concentrated (SC's) or flowable (F's), all with very good agitation to ensure a homogenous suspension. Next 

follow with water miscible concentrates and emulsifiable concentrates (EC's) before adding additives. After agitation, there 

must be a homogeneous suspension. Let the final tank mixture stand and observe for any rapid settling or floating of 

components. If any indications of physical incompatibility develop, do not use this mixture for spraying. 

Spray Equipment Cleanout 

The mix tank and spray equipment cleanout is an important stewardship activity to avoid injury to desirable crops. It is 

important to clean all mixing and spraying equipment immediately after use and before using pesticide products including 

this product. To clean the spraying equipment, follow the procedure outlined below: 

• Completely drain the mix tank and/or sprayer, and then wash thoroughly the tank, sprayer, boom and nozzles with 

clean water. Drain the system again. 

• Fill the mixing or spray tank half full with clean water and add domestic ammonium, normally a 3% solution, at a 

dilution rate of 1% vol/vol ammonium or I gallon per 100 gallons ofrinsate. 

• Completely fill the tank(s) with additional clean water. Agitate and recirculate and flush out the boom and hoses. Let 

the system run for 10 - 15 minutes. Drain the system completely. 

• Remove nozzles and screens and dislodge any visible solid material. Then soak them in a 1% vol/vol ammonium 

solution. Inspect the nozzles and screen and remove any visual residues. 

• Repeat the above procedure for a second time. 

• Flush the mix tank and/or sprayer, boom and hoses with clean water. Drain the system again and inspect for any 

visible residues. If present, repeat the cleaning cycle again. 

• If the rinsate cannot be disposed of by use according to label instructions, contact your State Pesticide or 

Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional Office for 

guidance. 

Aerial Application Methods and Equipment 

Spray Drift Management 

Do not allow this product to drift onto neighboring crops or non-crop area or use in a manner or at a time other than in 

accordance with label directions because animal, plant or crop injury, illegal residues or other undesirable results may occur. 

A voiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment and 

weather related factors determine the potential for spray drift. The applicator and the grower are responsible for considering 

all these factors when making decisions. The following drift management requirements must be followed to avoid off-target 

drift movement from aerial applications to agricultural field crops. These requirements do not apply to forestry applications, 

public health uses or to applications using dry formulations. 

I. The distance of the outer most nozzles on the boom must not exceed 314 the length of the wingspan or rotor. 

Aceto Mepiquat Chloride 4.2%PGR

2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 

degrees. Where states have more stringent regulations, they must be observed. 

The applicator should be fumiliar with and take into account the information covered in the publication titled A Summary of 

Arial Application Studies by the Spray Drift Task Force. 

The importance of spray droplet size: 

The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the 

largest droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential but may not 

prevent drift if applications are made improperly or under unfavorable environmental conditions (see the following "Wind", 

''Temperature and Humidity" and "Temperature Inversion" sections of this label). 

Controlling initial droplet size: 

• Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher flow rates 

producer larger droplets. Use a minimum of 5 gallons of water per acre. Increase water volume to at least 10 

gallons of water per acre. Increase water volume to at least 10 gallons of water per acre if grass foliage or crop 

canopy is dense. 

• Pressure - Use the lower spray pressures listed for tbe nozzle. Higher pressure reduces droplet size and does not 

improve canopy penetration. When higher flow rates are needed, use higher flow rate nozzles instead of increasing 

pressure. Use up to 40 psi. 

• Number of nozzles - Use the minimum number of nozzles that provide uniform coverage. 

• Nozzle orientation - Orienting nozzles so the spray stream is released backwards, parallel to air stream will produce 

larger droplets than other orientations. Significant deflection from the horizontal will reduce droplet size and 

increase drift potential. 

• Nozzle type- Use a nozzle type that is designed for the intended application. With most nozzle types, narrower 

spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back 

produce larger droplets than other nozzle types. Use only diaphragm-type nozzles that produce fan spray patter 

Boom Length: For some use patterns, reducing the effective boom length to less than :y. of the wingspan or rotor length may 

future reduce drift without reducing swath width. 

Application Height: Applications should be made at a height greater than 10 feet above the top of the largest plants. Making 

applications at the lowest height is safe reduces exposure to droplets to evaporation and wind. 

Swath adjustment - When applications are made with a cross-wind, the swath will be displaced downwind. Therefore, on the 

up and downwind edges of the field, the applicators must compensate for this displacement by adjusting the path of the 

aircraft upwind. Swath adjustment distances should increase drift potential (wind speed, droplet size, etc.) 

Wind - Drift potential is the lowest between wind speeds of2 to 10 mph. However, many factors including droplet size and 

equipment type determine drift potential at any given speed. Application must be avoided when wind speeds are below 2 

mph due to variable wind direction and high inversion potential. Do not apply this product by aircraft when wind is blowing 

more than 10 mph. NOTE: Local terrain can influence wind patterns. Applicators must be familiar with local wind patterns 

and how they affect drift. 

Temperature and humidity - When making applications inlow relative humidity set up equipment to produce larger droplets 

to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 

Temperature Inversions Do not apply during a temperature inversion because drift potential is high. Temperature 

inversions restrict vertical air mixing, which caUses small suspended droplets to remain in a concentrated cloud. This cloud 

can mOve in unpredictable directions due to the light variable air currents that are common during inversion. Temperature 

inversions are characterized by increasing temperatures which altitude and are common on nights with limited cloud cover 

and light to no wind. They begin to fonn as the sun sets and often continue into the morning. Their presence can be 

indicates by ground fog; however, if fog is not present, inversion can also be identified by the movement of smoke from a 

ground source or an aircraft smoke detector. Smoke that layers and moves laterally in a concentrated cloud (under low wind 

conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 

Sensitive areas:

! 

Use pesticides product adjacent to sensitive areas only when there is minimal potential for drift or off target movement, e.g. 

wind is blowing away from non-target crops, residential areas, bodies afwater, known habits for threatened or endangered 

species, etc. Do not apply this product by air if sensitive species are within 200 feet downwind. 

APPLICATION INSTRUCTIONS 

Early Application 

On both short-staple and Pima cotton, the grower has the option of low rate multiple applications (see Table I) or higher, less 

frequent dosages (see Table II) which greatly facilitates his management flexibility. The multiple application option gives 

the producer the ability to discontinue usage of this product if any significant stresses occur after an earlier application. In 

such a case, the total quantity of this product used over a season may be reduced. If stress is relieved, the grower has the 

option of continuing treatments with this product. In addition, the rate and timing ranges indicated in the Application Rates 

and Timing Tables allow the grower to tailor his usage of this product to the degree of vegetative vigor in a given field. In 

areas where insecticides, miticides or foliar fertilizers are frequently applied, the timings are such that tank mixing is often 

possible. (See Cotton Restrictions and Precautions) 

Fields should be carefully scouted and this product should not be applied if plants are under severe stress from weather 

rnctors, mite, insect or nematode damage, disease stress, herbicide injury, or fertility stress. In the absence of these stresses, 

up to 5 low rate multiple applications can be made each season. After the first application, (at matchhead square in the 

absence of stress), the rate and timing of subsequent applications will depend on vegetative vigor. Under good growing 

conditions, additional treatments should be at 7-14 day intervals. However, ifnew growth at any time is excessive, higher 

rates of this product can be used. 

If significant loss of squares or young bolls has occurred early due to insect pressure or other stresses, but now these stresses 

have been alleviated the need for this product is increased - excess vegetative growth is likely because of poor fruit load. 

Late Season Application 

Late application of this product (approximately during the fourth to sixth week of blooming) can provide certain benefits to 

cotton. However, it should not and does not substitute for early season use - the time of the greatest benefit from the use of 

this product. Late season application can lead to one or more of the following: 

• Reduction in late season vegetative growth or regrowth after cutout of defoliation 

• More complete and manageable cutout 

• Better defoliation 

• Early maturity 

• Reduction in trash 

• Lower ginning cost 

Some of these effects may favorably influence the yield potential and fiber quality. A late season application of this product 

should be applied only if fields are not drought or nutrient stressed; that is, those fields likely to experience additional 

vegetative growth or regrowth. However, fields that are very rank and extremely vigorous due to a combination of poor boll 

load and excellent growing conditions may not respond as much as desired to late season applications at the suggested rates. 

Time for Late Season Applications 

On fields where cotton cuts outs and then starts regrowth: Apply when regrowth begins, as evidenced by new leaves in 

the tenninal and stem elongation. This application time is often, but not always, 5-6 weeks after first bloom. 

On fields where cotton never com pletely cuts out: Apply this product where there are 4-6 nodes above the white flower 

(NA WF). Measure NA WF by counting the number of mainstem nodes from the first position white bloom (the closest to the 

mainstem) to the tenninal. Count the node with the first position white bloom as zero and the last node in the tenninal, which 

is counted, should have leaf at least the size ofa quarter. Generally, the NA WF first reaches 4-6 notes during the fourth to 

sixth week of bloom. During this time, the NA WF should be decreasing about one node every 5-6 days - ifits rate of 

decrease is less, the plant is not cutting out soon enough (the crop is too vigorous). If the fifth week of bloom arrives and the 

NA WF is still above 5-6, apply this product. 

Use Rate for Late Season Application 

Apply 8-24 fl. oz. of this product per acre. Use the lower rate on cotton with only moderate additional growth potential, and 

the higher rate on fields likely to continue vigorous growth.

A. During the 21 day initial content review, all eSFs will be reviewed to determine 

whether all inerts listed, including fragrances, are approved for the proposed uses. If an 

unapproved inert is identified, the applicant must either 1) resolve the inert issue by, for 

example, removing the inert, substituting it with an approved inert, submitting 

documentation that EPA approved the inert for the proposed pesticidal uses, correcting 

mistakes on the eSF, etc. or 2) provide the data to support OPP approval of the inert or 3) 

withdraw the application. Removing or substituting an inert ingredient will require a new 

eSF and may require submission of data. All information, forms, data and 

documentation resolving the inert issue must have been received by the Agency or the 

application withdrawn within the 21 day period. otherwise, the Agency will reject the 

application as described below. 

To successfully complete this aspect of the 21 day initial content screen, applicants are 

strongly encouraged to verify' that all inert ingredients have been approved for the 

application's uses even if a product is currently registered by consulting the inert Web 

3 
47

site [link to http://www.epa.gov/opprd001/inertslIists.html] and if the inert is not 

approved, to obtain the necessary inert approval prior to submitting an application 

to register a pesticide product containing that inert ingredient. Some inert 

ingredients are no longer approved for food uses or certain types of uses. The name 

andlor CAS number on a CSF must match the name and CAS number on this web site. 

Simple typographical errors in the name or CAS number have resulted in processing 

delays. 

If an inert is not listed on the inert ingredient web site and the applicant believes that the 

inert has been approved, the applicant should contact the Inert Ingredient Assessment 

Branch (IIAB) at inertsbranch@,epa.govandresolvetheissue. Copies of the 

correspondence with IIAB resolving the issue should accompany the application. All 

new inerts except PIP inerts are reviewed by IIAB. The IIAB should also be contacted 

for any questions on what supporting data needs to be submitted for and the Agency's 

inert review process. Questions on PIP inerts should be directed to the Chief of 

Microbial Pesticides Branch (Link to 

http://www.epa.gov/oppbppd1Ibiopesticides/contacts bppd.htmJ. 

When a brand, trade, or proprietary name of an inert ingredient is listed on a CSF, 

additional information such as an alternate name of the inert, CAS number or other 

infonnation [link to ht!p://www.epa.gov/opprdOOllinerts/tips.pdf] must also be included 

to enable the Agency to detennine if it has been approved. Each component of an inert 

mixture (including a fragrance) must be identified. In some cases, the supplier of the 

mixture or fragrance may need to provide this infonnation to the Agency. Prior to the 

Agency's receipt of an application, applicants must arrange with a proprietary mixture or 

fragrance supplier to provide the component information to the Agency or promptly upon 

EPA's request. If the inert ingredients in a proprietary blend (including fragrances) 

cannot or are not identified or provided within the 21-day content review period, the 

Agency will reject the application. 

During the 21 day content review, applicants should submit information to the individual 

identified by the Agency when the applicant is informed of an unapproved inert. 

Unapproved Inerts Identified on CSFs 

All applications except conventional new products and PIPs 

Once an unapproved inert is identified on a CSF, the Agency will contact the 

applicant with the following options; 

1. Correct the application by, for instance, correcting the inert's identity or CAS 

number, providing documentation that the inert has been approved, or 

removing the unapproved inert from the CSF or replacing it with one that is 

approved for the application's uses; or 

2. Submit the information and data needed for the Agency to approve the 

unapproved inert. If this option is selected and implemented, the Agency may 

request an extension in the PRIA decision review timeframe to accommodate 

the inert review/approval process; 

4 
48

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

If none of these options is selected and implemented by the applicant within the 

21 day content review period, the Agency will reject the application and retain 

25% of the full fee of the category identified. 

Conventional New Product Applications 

When the Registration Division identifies an unapproved inert on a CSF with an 

application for a new product that the applicant has not identified as requiring an 

inert approval (R311, R312 or R313), it will contact the applicant with the 

following options: 

1. Correct the application by, for instance, correcting the inert's identity or CAS 

number, providing documentation that the inert has been approved, or 

removing the unapproved inert from the CSF or replacing it with one that is 

approved for the application's uses; or 

2. Submit the information and data needed for the Agency to approve the 

unapproved inert, including any required petition to establish or amend a 

tolerance or exemption from a tolerance. (This option may change the PR1A 

category for the application, which cQuld require a longer decision review 

time and a larger fee. If additional fees are due, they must be received by the 

Agency within the 21 day content review period.) 

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

If none of the above options is selected and implemented during the 21-day 

content-review period, the Agency will reject the application and retain 25% of 

the appropriate fee for the new product-inert approval category. 

PIP Applications 

When the Biopesticide and Pollution Prevention Division identifies an 

unapproved inert on a PIP CSF and a request to approve the inert does not 

accompany the application, it will contact the applicant with the following 

options: 

1. Correct the application by, for instance, correcting the speliing or name of the 

inert to that in 40 CFR 174, or providing documentation that the inert has been 

approved; or 

2. Submit the infonnation and data needed for the Agency to approve the 

unapproved inert. If an inert ingredient tolerance exemption petition is 

required, the petition must be received by the Agency and the B903 fee paid 

within the 21 day period. If this option is selected and implemented, the 

Agency will discuss harmonizing the timeframe for both actions. 

5 
49

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

If none of the above options is selected and implemented during the 21 day 

content review period, the Agency will reject the application and retain 25% of 

the fee. 

B. A policy on documentation of offers to pay is still being developed, however, for a 

me-too or fast track (similar/identical) new product, R300 or A530, an application 

without the necessary authorizations of offers to pay will be placed into either R301 or 

A531. The Agency recommends that authorizations of offers to pay be submitted with 

other PRIA applications to avoid delays in the Agency's decision. 

C. Biopesticide applicants are advised to contact the Agency and discuss study waivers 

prior to submitting their application to the Agency, Documentation of such discussions 

should be submitted with the study waiver.

67

Aceto Mepiquat Chloride 4.2% PGR is a plant regulator for use on cotton. This product is use in a foliar application to help 

manage the cotton plant for short season production. This aHows the grower to reduce the risk of yield loss and quality loss 

due to delayed and prolonged harvest cycles. The use of this product also offers additional benefits including less boll rot, 

reduction in plant height with more open canopy, increased early boll retention and/or large bolls, improved defoliation with 

less trash, lower ginning costs, better harvest efficiency and richer dark green leaf color. Nonnally most of these benefits 

favorably enhance the yield potential of the cotton plant. 

Spray Coverage 

Unifonn, thorough spray coverage of cotton foliage is important to achieve consistent performance. Calibrate application 

equipment according to manufacturer's specifications. Use nozzle type arrangements that provide optimum spray 

distribution and maximum coverage. 

In most applications, water is the preferred diluent, however oil for ultra low volume (UL V) aerial applications is allowed in 

the following states:

Water as Diluent: Use 2 gallons of spray solution per acre in all states except California. In California, use a minimum of 5 

gallons per acre. 

AIR Application 

Water as Diluent: Use a minimum of2 gallons of water per acre in all states except California. In California, use a 

minimum of 5 gallons per acre. 

Oil as Diluent: Use a minimum of 1 quart of oil per acre. When using oil as a diluent, the oil concentrate must contain 

either a petroleum or vegetable oil base and must meet all ofthe following criteria: 

Be nonphytotoxic 

Contain only EPA-exempt ingredients 

Provide good mixing quality in the jar test 

Be successful in local experience 

The exact composition of suitable products will vary, however, vegetable and petroleum oil concentrates should contain 

emulsifies to provide good mixing quality. Ifthe oil does not contain an emulsifier, one must be added during missing at a 

volume equal to 3% of the final volume of the mixing tank. Do not apply this product ULV without using emulsifiers. 

Highly refmed vegetable oils have proven more satisfactory than unrefmed vegetable oils. For additional information see

Clean sprayer parts immediately after using this product by thoroughly flushing with water. 

This product mixes readily with water. Mix spray solutions of this product as follows: 

Fill the mixing or spray tank with the required amount of water. 

Add the specified amount of this product near the end of the filling process and mix well. 

• Use caution to avoid siphoning back into the carrier source. Use approved anti~back-siphoning devices required by state 

or local regulations. 

During mixing and application, foaming of the spray solution may occur. To prevent or minimize foam, avoid the use of 

mechanical agitators, terminate by-pass and return lines at the bottom of the tank and, ifneeded, use an approved antifoam or defoaming agent. 

Tank Mixing Procedure: 

Always predetermine the compatibility of labeled tank mixtures of this product with water or oil diluent by mixing small 

proJXlrtional quantities in advance. Use a smail container and mix all components in a small amount, usuaily 0.5 to 1 qt. of 

spray. Combine all products in the same ratio and order of addition as in the proposed spray mixture. Observe the mixture for 

indication of incompatibility which usual occurs in 10 to 30 minutes after mixing. If incompatibility is observed, try changing 

the order of addition of the components. The guideline on tank mixture partners is driven by formulation type. Start with 

wettable powders (WP's) including water soluble bags (WSB's), water dispersible granules (WDG's), dry flowables (OF), 

suspension concentrated (SC's) or flowable (F's), all with very good agitation to ensure a homogenous suspension. Next 

follow with water miscible concentrates and emulsifiable concentrates (BC's) before adding additives. After agitation, there 

must be a homogeneous suspension. Let the final tank mixture stand and observe for any rapid settling or floating of 

components. If any indications of physical incompatibility develop, do not use this mixture for spraying. 

Spray Equipment C1eanout 

The mix tank and spray equipment c1eanout is an important stewardship activity to avoid injury to desirable crops. It is 

important to clean all mixing and spraying equipment immediately after use and before using pesticide products including 

this product. To clean the spraying equipment, follow the procedure outlined below: 

• Completely drain the mix tank and/or sprayer, and then wash thoroughly the tank, sprayer, boom and nozzles with 

clean water. Drain the system again. 

• Fill the mixing or spray tank half full with clean water and add domestic anunonium, normaily a 3% solution, at a 

dilution rate of 1% voVvol ammonium or I gallon per 100 gallons ofrinsate. 

• Completely fill the tank(s) with additional cleau water. Agitate and recirculate and flush out the boom and hoses. Let 

the system run for 10 - 15 minutes. Drain the system completely. 

• Remove nozzles and screens and dislodge any visible solid material. Then soak them in a 1% voVvo1 ammonium 

solution. Inspect the nozzles and screen and remove any visual residues. 

• Repeat the above procedure for a second time. 

• Flush the mix tank and/or sprayer, boom and hoses with clean water. Drain the system again and inspect for any 

visible residues. If present, repeat the cleaning cycle again. 

• If the rinsate cannot be disposed ofby use according to label instructions, contact your State Pesticide or 

Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional Office for 

guidance. 

Aerial Application Methods and Equipment 

Spray Drift Management 

Do not ailow this product to drift onto neighboring crops or non-crop area or use in a manner or at a time other than in 

accordance with label directions because animal, plant or crop injury, illegal residues or other undesirable results may occur. 

Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment and 

weather related factors determine the potential for spray drift. The applicator and the grower are responsible for considering 

all these factors when making decisions. The following drift management requirements must be followed to avoid off-target 

drift movement from aerial applications to agricuhural field crops. These requirements do not apply to forestry applications, 

public health uses or to applications using dry formulations. 

I. The distance of the outer most nozzles on the boom must not exceed Yo the length of the wingspan or rotor. 

Aceto Mepiquat Chloride 4.2% PGR

Page 4 of9

2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 

degrees. Where states have more stringent regulations, they must be observed. 

The applicator should be familiar with and take into account the information covered in the publication titled A Summary of 

Arial Application Studies by the Spray Drift Task Force. 

The importance of spray droplet size: 

The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the 

largest droplets that provide sufficient coverage and controL Applying larger droplets reduces drift potential but may not 

prevent drift if applications are made improperly or under unfavorable environmental conditions (see the following "Wind", 

"Temperature and Humidity" and "Temperature Inversion" sections of this label). 

Controlling initial droplet size: 

• Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher flow rates 

producer larger droplets. Use a minimum of 5 gallons of water per acre. Increase water volume to at least 10 

gallons of water per acre. Increase water volume to at least 10 gallons of water per acre ifgrass foliage or crop 

canopy is dense. 

• Pressure - Use the lower spray pressures listed for the nozzle. Higher pressure reduces droplet size and does not 

improve canopy penetration. When higher flow rates are needed, use higher flow rate nozzles instead of increasing 

pressure. Use up to 40 psi. 

• Number of nozzles - Use the minimum number of nozzles that provide uniform coverage. 

• Nozzle orientation - Orienting nozzles so the spray stream is released backwards, parallel to air stream will produce 

larger droplets than other orientations. Significant deflection from the horizontal will reduce droplet size and 

increase drift potential. 

• Nozzle type- Use a nozzle type that is designed for the intended application. With most nozzle types, narrower 

spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back 

produce larger droplets than other nozzle types. Use only diaphragm-type nozzles that produce fan spray patter 

Boom Length: For some use patterns, reducing the effective boom length to less than % of the wingspan or rotor length may 

future reduce drift without reducing swath width. 

Application Height: Applications should be made at a height greater than 10 feet above the top of the largest plants. Making 

applications at the lowest height is safe reduces exposure to droplets to evaporation and wind. 

Swath adjustment - When applications are made with a cross-wind, the swath will be displaced downwind. Therefore, on the 

up and downwind edges of the field, the applicators must compensate for this displacement by adjusting the path of the 

aircraft upwind. Swath adjustment distances should increase drift potential (wind speed, droplet size, etc.) 

Wind - Drift potential is the lowest between wind speeds of2 to 10 mph. However, many factors including droplet size and 

equipment type determine drift potential at any given speed. Application must be avoided when wind speeds are below 2 

mph due to variable wind direction and high inversion potentiaL Do not apply this product by aircraft when wind is blowing 

more than 10 mph. NOTE: Local terrain can influence wind patterns. Applicators must be familiar with local wind patterns 

and how they affect drift. 

Temperature and humidity When making applications in low relative humidity set up equipment to produce larger droplets 

to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 

Temperature Inversions Do not apply during a temperature inversion because drift potential is high. Temperature 

inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. This cloud 

can move in unpredictable directions due to the light variable air currents that are common during inversion. Temperature 

inversions are characterized by increasing temperatures which altitude and are common on nights with limited cloud cover 

and light to no wind. They begin to form as the sun sets and often continue into the morning. Their presence can be 

indicates by ground fog; however, if fog is not present, inversion can also be identified by the movement of smoke from a 

ground source or an aircraft smoke detector. Smoke that layers and moves laterally in a concentrated cloud (under low wind 

conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 

Sensitive areas: 

Aceto Mepiqual Chloride 4.2% PGR 

December 8, 2010 

Page 5 of9 
70

Use pesticides product adjacent to sensitive areas only when there is minimal potential for drift or off target movement, e.g. 

wind is blowing away from non~target crops, residential areas, bodies of water, known habits for threatened or endangered 

species, etc. Do not apply tbis product by air if sensitive species are within 200 feet downwind. 

APPLICA nON INSTRUCTIONS 

Early Application 

On both shorHtaple and Pima cotton, the grower has the option oflow rate multiple applications (see Table I) or higher, less 

frequent dosages (see Table II) which greatly facilitates his management flexibility. The multiple application option gives 

the producer the ability to discontinue usage of this product if any significant stresses occur after an earlier application. In 

such a case, the total quantity of this product used over a season may be reduced. If stress is relieved, the grower has the 

option of continuing treatments with this product. In addition, the rate and timing ranges indicated in the Application Rates 

and Timing Tables allow the grower to tailor his usage of this product to the degree of vegetative vigor in a given field. In 

areas where insecticides, miticides or foliar fertilizers are frequently applied, the timings are such that tank mixing is often 

possible. (See Cotton Restrictions and Precautions) 

Fields should be carefully scouted and this product should not be applied if plants are under severe stress from weather 

factors, mite, insect or nematode damage, disease stress, herbicide injury, or fertility stress. In the absence of these stresses, 

up to 5 low rate multiple applications can be made each season. After the first application, (at matchhead square in the 

absence of stress), the rate and timing of subsequent applications will depend on vegetative vigor. Under good growing 

conditions, additional treatments should be at 7~14 day intervals. However, ifnew growth at any time is excessive, higher 

rates of this product can be used. 

If significant loss of squares or young bolls has occurred early due to insect pressure or other stresses, but nOw these stresses 

have been alleviated the need for this product is increased - excess vegetative growth is likely because of poor fruit load. 

Late Season Application 

Late application of this product (approximately during the fourth to sixth week of blooming) can provide certain benefits to 

cotton. However, it should not and does not substitute for early season use - the time of the greatest benefit from the use of 

this product. Late season application can lead to one or more of the following: 

• Reduction in late season vegetative growth or regrowth after cutout of defoliation 

• More complete and manageable cutout 

• Better defoliation 

• Early maturity 

• Reduction in trash 

• Lower ginning cost 

Some of these effects may favorably influence the yield potential and fiber quality. A late season application of this product 

should be applied only if fields are not drought or nutrient stressed; that is, those fields likely to experience additional 

vegetative growth or regrowth. However, fields that are very rank and extremely vigorous due to a combination of poor boll 

load and excellent growing conditions may not respond as much as desired to late season applications at the suggested rates. 

Time for Late Season Applications 

On fields where cotton cuts outs and then starts regrowth: Apply when regrowth begins, as evidenced by new leaves in 

the terminal and stem elongation. This application time is often, but not always, 5-6 weeks after first bloom. 

On fields where cotton never completely cuts out: Apply this product where there are 4-6 nodes above the white flower 

(NA WF). Measure NA WF by counting the number of main stem nodes from the first position white bloom (the closest to the 

mainstem) to the terminal. Count the node with the first position white bloom as zero and the last node in the tenninal, which 

is counted, should have leaf at least the size of a quarter. Generally, the NA WF first reaches 4-6 notes during the fourth to 

sixth week of bloom. During this time, the NA WF should be decreasing about one node every 5-6 days - ifits rate of 

decrease is less, the plant is not cutting out soon enough (the crop is too vigorous). If the fifth week of bloom arrives and the 

NA WF is still above 5-6, apply this product. 

Use Rate for Late Season Application 

Apply 8-24 fl. oz. of this product per acre. Use the lower rate on cotton with only moderate additional growth potential, and 

the higher rate on fields likely to continue vigorous growth.
