## , ,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 toreduce therisk 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, betterharvest efficiency andricher dark green leafcolor. Most of these benefits may fuvorably enhance the yield potential ofthe cotton plant. Spray Coverage Unifurm, thorough spray coverage ofcotton fuliage is important to achieve consistent performance. Calibrate application equipment according to manufacturer's specifications. Use nozzle type arrangements that provide optimum spray distribution andmaximum coverage. In most applications, water is the preferred diluent, however oil fur 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: Use 2 gallons ofspray 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 ofwater per acre in all states except Califurnia. In California, use a minimum of5 gallons per acre. Oil as Diluent: Use a minimum ofl quart ofoil 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 thejartest Be successful in local experience The exact composition ofsuitable products will vary; however, vegetable and petroleum oil concentrates should contain emulsifies to provide good mixing quality. Ifthe oil does not contain an emulsifier, onernustbe added during mixing at a volume equal to 3% ofthe final volume of themixing tank. Do not applythis product by ULVwithout using emulsifiers. Highly refined vegetable oils have proven more satisfuctory than unrefined vegetable oils. For additional information see TankMixing Procedure. Additives

This product mixes readily with water. Mix spray solutions of this product as follows: Fill the mixing or spray tank with therequired amount ofwater. Addthe specified amount of this productnear 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 theuse of mechanical agitators, terminate by-pass andreturn lines atthe bottom ofthe tank and, ifneeded, use an approved antifoam or defuaming agent. Tank MixingProcedure: Always predetermine the compatibility oflabeled tank mixtures ofthis product with water or oil diluent bymixing small proportional quantities in advance. Use a small container andmix ail components in a small amount, usually 

### 0.5 to Iqt. of spray. Combine all products in the sameratio and order ofaddition as in the proposed spray mixture. Observe themixture for indication ofincompatibility which usual occurs in 

### 10 to 

### 30minutes after mixing. Ifincompatibility is observed, try changing the order ofaddition 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. Letthe final tank mixture stand and observe for anyrapid settling or floating of components. Ifany indications ofphysical incompatibility develop, donot use this mixture for spraying. Spray Equipment Cleanout Themix tank and spray equipment cleanout is an important stewardship activity to avoid injury to desirable crops. It is importantto clean all mixing and spraying equipment immediately after use and before using pesticide products including this product. To clean the spraying equipment, follow theprocedure outlinedbelow:

• Completely drain the mix tank and/or sprayer, and then wash thoroughly thetank, sprayer, boom and n02'Zles with clean water. Drain the system again. • Fill themixing or spray tankhalffull with clean water and add domestic ammonium, normally a 3% solution, at a dilution rate of1% vol/vol ammonium or I gallon per 

### 100 gallons ofrinsate. • Completely fill the tank(s) with additional clean water. Agitate andrecirculate and flush out theboom and hoses. Let the system run for 10

- 15 minutes. Drain the system completely. • Remove nozzles and screens and dislodge anyvisible solid material. Then soak them in a I % vol/vol ammonium solution. Inspect thenozzles and screen andremove any visual residues. • Repeat the above procedure for a second time. • Flush the mix tank and/or sprayer, boom andhoses with clean water. Drain the system again and inspect for any visible residues. Ifpresent, repeat the cleaning cycle again. • If therinsate cannot be disposed of by use acrording to label instructions, contact your State Pesticide 0$, •• Environmental Control Agency, orthe Hazardous Waste representative atthenearest EPARegional O'tnCf)

The applicator and the grower areresponsible 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. Theserequirements donot apply to furestry applications, public health uses or to applications using dry formulations. Aceto MepiquatChloride4.2% PGR April 5, 2011 Final Print Label Page 4 of91. The distance ofthe 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 bythe Spray Drift Task Force. The importance ofspray droplet size: The most effective way toreduce 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 ifapplications 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 ratenozzles to applythehighest practical spray volume. Nozzles with higher flow rates producer larger droplets. Use a minimum of5 gallons ofwater 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 areneeded, use higher flow rate nozzles instead ofincreasing pressure. Use up to 40 psi. • Number ofnozzles

- 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 withoutreducing 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 swathwill be displaced downwind. Therefore, on the up and downwind edges ofthefield, the applicators must compensate for this displacement by adjusting the path ofthe aircraft upwind. Swath adjustment distances should increase drift potential (wind speed, droplet size, etc.) Wind

- Drift potential is the lowest between wind speeds of2to 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 windpatterns. Applicators must be familiarwith local wiPP,natterns and howtheyaffect drift.

APPLICATION INSTRUCTIONS EarlyApplication On both Short-staple and Pima cotton, thegrower has the option oflow rate multiple applications (see Table I) or higher, less frequent applications (see Table II)which greatly facilitates his management flexibility. Themultiple application option gives theproducer the ability to discontinue usage of this product ifany significant stresses occur after an earlier application. In such a case, thetotal quantity ofthis product used over a season may be reduced. Ifstress is relieved, the grower has the option ofcontinuing treatments with this product.

AcelO Mepiquat Chloride4.2% POR April 5, 2011 Final Prin! Label Page 1 of9Product Information Aceto Mepiquat Chloride 4.2%PGR is a plant regulator for use on cotton. Thisproduct is use in a foliar application to help manage the cotton plant for short season production. This allows the grower toreduce 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 leafcolor. Most ofthese 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 the following states: Alabama U:lUisiana Oklahoma SprayVolume GROUND Application Arkansas Missouri South Carolina Florida Mississippi Tennessee Georgia North Carolina Texas

Water as Diluent: Use 2 gallons ofspray 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 ofwater per acre in all states except California. In Califumia, use a minimum of5 gallons per acre. Oil as Diluent: Use a minimum ofI quart ofoil per acre. When using oil as a diluent, the oil concentrate must contain either a petroleum orvegetable oU base and must meet all of the following criteria: Be nonphytotoxic Contain only EPA-exempt ingredients Provide good mixing quality in thejar test Be successful in local experience The exact composition ofsuitableproducts will vary; however, vegetable and petroleum oil concentrates should contain emulsifies to provide good mixing quality. Iftheoil does not contain an emulsifier, one must be added during mixing at a volume equal to 3%of the final volume ofthe mixing tank. Do not apply this product by ULV without using emulsifiers. Highly refined vegetable oils have proven more satisfactory than unrefined vegetable oils. For additional information see TankMixing Procedure.

Where states have more stringent regulations, they mustbe 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 ofspray droplet size: The most effective way to reduce drift potential is to apply large droplets. Thebest drift management strategy is to apply the largest droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential butmay not prevent drift ifapplications 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 thehighest practical sprayvolume. Nozzles with higher flow rates producer larger droplets. Use a minimum of5 gallons ofwater per acre. Increase water volume to at least 10 gallons ofwater 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. Higherpressure reduces droplet size and does not improve canopypenetration. When higher flow rates areneeded, use higher flow ratenozzles instead ofincreasing pressure. Use up to 40 psi. • Number ofnozzles

- Use the minimwn number ofnozzles thatprovide 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 mostnozzle types, narrower spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back produce larger dropletsthan othernozzle 

### types. Use only diaphragm-type nozzles thatproduce 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 heightgreater than 10 feet above the top ofthe largest plants. Making applications atthe 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 adjustingthe path ofthe aircraft upwind. Swath adjustment distances should increase driftpotential (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 mustbe avoided when wind speeds are below 2 mph due to variable wind direction andhigh inversion potential. Do not apply this product by aircraft when wind is blowing more than 10 mph.

APPLICATION INSTRUcrIONS EarlyApplication On both short-staple and Pima cotton, the grower has the option oflow rate multiple applications (see TableI) or higher, less frequent applications (see Table II)which greatly facilitates his management flexibility. Themultiple application optien gives theproducer the ability to discontinue usage ofthis product ifany significant stresses occur after an earlier application. In such a case, the total quantity ofthis product used over a season may bereduced. Ifstress is relieved, the grower has the option ofcontinuing 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 shouldnot be applied ifplants areunder 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 ofstress), therate and timing ofsubsequent 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. Ifsignificant loss ofsquares oryoung bolls has occurred early due to insect pressure or other stresses, butnowthese stresses havebeen alleviated the need for this product is increased

- excess vegetative growth is likely because ofpoor boil load. Late Season Application Late application of this product (approximately during the fourth to sixth week ofblooming) 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 thisproduct. Late season application can lead to one or more ofthe following:

• Reduction in late season vegetative growth or regrowth after cutout ofdefoliation • More complete and manageable cutout • Better defoliation • Early maturity • Reduction in trash • Lower ginning cost Some of these effects may fuvorably influence theyield potential and fiber quality. A late season application of this product should 

### be applied only iffields arenot drought or nutrient stressed; that is, those fields likely to experience additional vegetative growth orregrowth. However, fields that are very rank and extremely vigorous due to a combination of poor bo1i load and excellent growing conditions may notrespond asmuch as desiredto late season applications atthe sspecified rates.

Product Information
Acelo Mepiqual Chloride 4.2%PGR December 8, 2010 Page2 of9

### Aceto Mepiquat Chloride 4.2%PGRis 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 growerto reduce the risk ofyield loss and quality loss dueto 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, betterharvest efficiency and richer dark green leafcolor. Nonnally most ofthese benefits favorably enhance the yield potential ofthe cotton plant. Spray Coverage Uniform, thorough spray coverage ofcotton foliage is importantto achieve consistent perfonnance. Calibrate application equipment accordingto 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 ofspray solution per acre in all states except California. In California, use a minimum of5 gallons peracre. AIR Application Water as Diluent: Use a minimum of2 gallons ofwater per acre in all states except California In 

### California, use a minimum of5 gallons per acre. Oil as Diluent: Use a minimum of 1quart ofoil peracre. 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 thejar test Be successful in local experience The exact composition ofsuitable 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% ofthe 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 Ifrain is anticipated within 8 hours, use a high quality, EPA exempt surfactant to make this product rainsafe after 4 hours. TankMixture Partner This product is awater based formulation and is compatible with most insecticide and miticide products. Ifthis product is utilized with a tank mixture partner(s), refer to the specific partner label(s) and observe all the precautionary statements and use directions including pre-harvest intervals, crop rotation restrictions, mixing and application instructions. Observe the most restrictive of the labeling limitations andprecautions ofall products used in mixtures. Tbis product may also be 

### usedwith foliar fertilizers ifprevious experience has demonstrated that the mixture is compatible and non-injurious under user's typical growing conditions. Perform a compatibility test for tank mixture partners before preparing atank mixture application. Mixing Aceto Mepiquat Chloride 4.2%POR December 8, 2010 Page 3 of9

### Clean sprayerparts immediately after using this productbythoroughly 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 ofwater. Addthe specified amount ofthis 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, terminate by-pass andreturn lines atthe bottom ofthe tank and, ifneeded, use an approved antifoam or defoaming agent. Tank MixingProcedure: Alwayspredetermine 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 

### inthe same ratio and order ofaddition as in the proposed spraymixture. Observe the mixture for indication ofincompatibilitywhichusual occurs in 10 to 30 minutes aftermixing. Ifincompatibility is observed, try changing the order ofaddition ofthe 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 mustbe a homogeneous suspension. Let the final tank mixture stand and observe for anyrapid settling orfloating of components. Ifany indications ofphysical incompatibility develop, do not use this mixture for spraying. Spray Equipment Cleanout Themix tank and spray equipment cleanout is an important stewardship activity to avoid injury to desirable crops. Itis important to clean all mixing and spraying equipment immediately after use and before using pesticide products including this product. To cleanthe spraying equipment, follow the procedure outlined below:

• Completely drain the mix tank and/or sprayer, andthen wash thoroughly the tank, sprayer, boom and nozzles with clean water. Drainthe system again. • Fill the mixing or spray tank halffull with cleanwater and add domestic ammonium, normally a 3% solution, at a dilution rate of1% vol/vol ammonium or I gallon per 100 gallons ofrinsate. • Completely fill the tank(s) with additional cleanwater. Agitate and recirculate and flush outthe boom and hoses. Let the systemrun for 10

- 15 minutes. Drainthe 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, repeatthe cleaning cycle again. • If the rinsate cannot 

### be disposed ofby use according to label instructions, contactyour State Pesticide or Environmental Control Agency, orthe Hazardous Waste representative atthenearestEPA Regional Office for guidance. Aerial Application Methods and Equipment Spray Drift Management Donot allow this productto drift onto neighboring crops ornon-crop area oruse in a manner or ata time otherthan in accordance with label directions because animal, plantorcrop injury, illegal residues or otherundesirable results may occur. Avoiding spray drift atthe application site is the responsibility ofthe 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 whenmaking decisions. The following drift managementrequirements must be followed to avoid off-target drift movement from aerial applicationsto 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 outermost nozzles ontheboom mustnot exceed 

### 314 the length ofthe wingspan orrotor. Aceto Mepiquat Chloride 4.2%PGR December8,2010 Page4of9

### 2. Nozzles must always point backward parallel with the air stream and neverbe pointed downwards more than 45 degrees. Where states have more stringent regulations, they must be observed. The applicator shouldbe fumiliar with andtake into account the information covered in the publication titled A Summary of Arial Application Studiesby the Spray Drift Task Force. The importance ofspray droplet size: Themost 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 driftifapplications are made improperly orunder 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 of5 gallons ofwaterperacre. Increase water volume to at least 10 gallons ofwaterperacre. Increase water volume to at least 10 gallons ofwaterper acre ifgrass foliage or crop canopy is dense. • Pressure
- Use the lower spraypressures listed for tbe nozzle. Higher pressure reduces droplet size and does not improve canopypenetration. When higher flow rates are needed, use higher flow rate nozzles instead ofincreasing pressure. Use up to 40 psi. • Number ofnozzles

- Use the minimum number ofnozzles 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 driftpotential. • Nozzle type- Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angles produce larger droplets. Considerusing 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. ofthe wingspan orrotor length may future reduce driftwithout reducing swathwidth. Application Height: Applications should be made at a heightgreaterthan 10 feet above thetop ofthe largest plants. Making applications atthe 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, onthe 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

- Driftpotential is the lowestbetween wind speeds of2 to 10 mph. However, many factors including droplet size and equipment type determine driftpotential at any given speed. Application mustbe avoided whenwind speeds are below 2 mph due to variable wind direction and high inversionpotential. Do not apply this product by aircraft when wind is blowing more than 10 mph. NOTE: Local terrain can influence wind patterns. Applicators must befamiliar with local wind patterns and how they affect drift. Temperature and humidity

- When makingapplications inlowrelative humidity setup 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 airmixing, 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 lighttono wind. They begin to fonn as the sun sets and often continue into the morning. Theirpresence canbe indicates by ground fog; however, iffog is not present, inversion can also be identified by the movement ofsmoke from a ground source or an aircraft smoke detector. Smoke that layers andmoves laterally in a concentrated cloud (under lowwind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical airmixing. Sensitive areas:

Aceto Mepiquat Chloride 4.2%POR December 8, 20lO Page 5 of91 ! Usepesticides product adjacent to sensitive areas only whenthere is minimal potential for 

### drift orofftarget 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 ifsensitive species are within 200 feet downwind. 

### APPLICATION INSTRUCTIONS Early Application On both short-staple and Pima cotton, the growerhas the option oflow rate multiple applications (see Table I) orhigher, less frequent dosages (see Table II) which greatly facilitates his management flexibility. The multiple application option gives the producerthe ability to discontinue usage of this product ifany significant stresses occur after an earlier application. 

### In such a case, the total quantity of this productused over a seasonmay be reduced. Ifstress is relieved, the grower has the option ofcontinuing treatments withthis product. In addition, the rate and timingranges indicated inthe Application Rates and Timing Tables allow the growerto tailorhis usage of this productto the degree ofvegetative vigor in a given field. In areas where insecticides, miticides or foliar fertilizers are frequently applied, thetimings are such thattank mixing is often possible. (See Cotton Restrictions and Precautions) Fields should be carefully scouted and this product should not be applied ifplants are under severe stress from weather rnctors, mite, insect or nematode damage, disease stress, herbicide injury, or fertility stress. 

### Inthe absence ofthese stresses, up to 5 low rate multiple applications canbe made each season. Afterthe first application, (atmatchhead square in the absence ofstress), the rate and timing ofsubsequent applications will depend on vegetative vigor. Undergood 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 beused. Ifsignificant loss ofsquares oryoung bolls has occurred early dueto insect pressure orother stresses, but nowthese stresses have been alleviated the need forthis product is increased

- excess vegetative growth is likely because ofpoor fruit load. Late Season Application Late application of this product (approximately duringthe fourth to sixth week ofblooming) canprovide certainbenefits to cotton. However, it shouldnot 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 ormore ofthe following:

• Reduction in late season vegetative growth orregrowth after cutout ofdefoliation • More complete and manageable cutout • Betterdefoliation • Early maturity • Reduction in trash • Lowerginning cost Some ofthese effects may favorably influence the yield potential and fiber quality. A late season application ofthis product should be applied only iffields arenot drought ornutrient stressed; that is, those fields likely to experience additional vegetative growth orregrowth. However, fields that are very rank and extremely vigorous dueto a combination of poorboll load and excellent growing conditions maynot respond as much as desired to late season applications atthe suggested rates. Time for Late Season Applications On fields where cotton cuts outs and then starts regrowth: Applywhen 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 completelycuts out: Applythis productwhere there are4-6 nodes above thewhite flower (NAWF). MeasureNAWF by countingthe number ofmainstemnodes from the first positionwhitebloom (the closest to the mainstem)to the tenninal. Countthe node with the first position white bloom as zero andthe last node 

### in the tenninal, which is counted, should have leafat least the size ofaquarter. Generally, theNAWF first reaches 4-6 notes during the fourth to sixth week ofbloom. Duringthis time, the NAWF 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 ofbloom arrives and the NAWF is still above 5-6, apply this product. Use Rate for Late Season Application Apply 8-24

AerialApplication Methods and Equipment Spray DriftManagement Do not ailow this product to 

### drift onto neighboring crops or non-crop area oruse in a manner or ata time otherthan 

### in accordance with label directions because animal, plant or crop injury, illegal residues or otherundesirable results may occur. Avoiding spray drift atthe application site is 

### the responsibility ofthe applicator. The interaction ofmany equipment and weather related factors determine the potential for spray drift. The applicator andthe grower are responsible for considering all these factors when making decisions. The following drift managementrequirements mustbe 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 orto applications using 

### dry formulations. I. The distance of the outer most nozzles onthe boommust not exceed 

### Yo the length ofthe wingspan orrotor. Aceto Mepiquat Chloride 4.2%PGR December 8, 2010 Page 4 of9

### 2. Nozzles must always point backwardparallel with the air stream andneverbe pointed downwards more than 45 degrees. Where states have more stringent regulations, theymust 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 ofspray 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 ifapplications are made improperly orunderunfavorable 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 of5 gallons ofwater peracre. Increase water volume to at least 10 gallons ofwater per acre. Increase water volume to at least 10 gallons ofwater per acre ifgrass foliage orcrop canopy is dense. • Pressure
- Use the lower spray pressures listed for the nozzle. Higherpressure reduces droplet size and does not improve canopypenetration. When higher flow rates are needed, use higher flow rate nozzles instead ofincreasing pressure. Use upto40 psi. • Number ofnozzles

- Use the minimum number of nozzles thatprovide uniform coverage. • Nozzle orientation

- Orienting nozzles sothe 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. Considerusing low-drift nozzles. Solid stream nozzles oriented straight back produce larger droplets than othernozzle types. Use only diaphragm-type nozzles that produce fan spraypatter Boom Length: For some use patterns, reducing the effective boom length to less than % 

### ofthe wingspan orrotor length may future reduce drift without reducing swathwidth. Application Height: Applications should be made at a height greater than 10 feet above the top ofthe 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 byadjusting the path ofthe aircraft upwind. Swath adjustment distances should increase drift potential (wind speed, droplet size, etc.) Wind

- Drift potential isthe 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 mustbe 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 windpatterns. Applicators must be familiar with local wind patterns and how they affect drift. Temperature andhumidity When making applications in lowrelative humidity setup 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 tothe 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. Theybegin to form as the sun sets and often continue into the morning. Their presence can be indicates by ground fog; however, iffog is notpresent, inversion can also beidentified by the movement ofsmoke 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 of9Use pesticidesproduct adjacent to sensitive areas only whenthere is minimal potential for drift orofftarget movement, e.g. wind is blowing away from**non~target** crops, residential areas, bodies ofwater, known habits for threatened or endangered species, etc. Do not apply tbis product by air ifsensitive species are within 200 feet downwind. APPLICA nON INSTRUCTIONS Early Application On both shorHtaple andPima cotton, the growerhas the option oflowrate multiple applications (see Table I) orhigher, less frequent dosages (see Table II)which greatly facilitates his management flexibility. Themultiple application option gives the producer the abilityto 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 maybereduced. Ifstress is relieved, the grower has the option ofcontinuing treatments withthis product. In addition, the rate and timing ranges indicated in the Application Rates and Timing Tables allow the growerto tailor hisusage ofthis product tothe degree ofvegetative vigor in a given field. In areas where insecticides, miticides or foliar fertilizers are frequently applied, the timings are suchthat tankmixing is often possible. (See Cotton Restrictions and Precautions) Fields should be carefully scouted and this product should not be applied ifplants are under severe stress from weather factors, mite, insect ornematode damage, disease stress, herbicide injury, or fertility stress. Inthe absence ofthese stresses, up to 5 low rate multiple applications can be made each season. Afterthe first application, (at matchhead square inthe absence ofstress), the rate and timing ofsubsequent applications will depend onvegetative vigor. Under good growing conditions, additional treatments should be at**7~14** day intervals. However, ifnewgrowth at any time is excessive, higher rates of this product canbe used. Ifsignificant loss ofsquares oryoungbollshas occurred earlydue to insect pressure orother stresses, but nOw these stresses have been alleviated the need for this product is increased

- excess vegetative growth is likely because ofpoor fruit load. Late Season Application Late application ofthis product (approximately duringthe fourth to sixth week ofblooming) canprovide 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 ormore ofthe following:

• Reduction in late season vegetative growth orregrowth after cutout ofdefoliation • More complete and manageable cutout • Betterdefoliation • Early maturity • Reduction in trash • Lower ginning cost Some ofthese effectsmay favorably influence the yield potential and fiber quality. A late season application ofthis product shouldbe applied only iffields arenot drought ornutrient stressed; that is, those fields likely to experience additional vegetative growth orregrowth. However, fields that are very rank and extremely vigorous due to a combination ofpoorboll 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: Applywhen regrowth begins, as evidenced bynew leaves in the terminal and stem elongation. This application time is often, butnot always, 5-6 weeks after first bloom. On fields where cotton never completely cuts out: Applythis product where there are 4-6 nodes above the white flower (NA WF). MeasureNAWF by counting the number ofmainstemnodes from the first position white bloom (the closest to the mainstem) to the terminal. Countthe nodewiththe first position white bloom as zero andthe last node in the tenninal, which is counted, should have leafat leastthe size ofa quarter. Generally, the NAWF first reaches 4-6 notes during the fourth to sixth week ofbloom. Duringthis time, theNAWF should be decreasing about onenode every 5-6 days

- ifits rate of decrease is less, theplant is not cutting out soon enough (the crop is too vigorous). If the fifth week ofbloom arrives and the NAWF is still above 5-6, apply this product. Use Rate for Late Season Application Apply 8-24 fl. oz. ofthis product per acre.
