1. GENERAL INFORMATION 

MEP 42 is a foliar applied plant regulator that modifies the cotton plant in several beneficial 

ways. It allows the grower to manage the cotton plant for short-season production leading to 

reduced risk of yield and quality loss due to delayed and prolonged harvest. Additional benefits 

derived from the use ofthis product include: 

• height reduction and more canopy 

• better early boll retention andlor larger bolls 

• less boll rot 

• improved defoliation 

• reduced trash and lower ginning costs 

• better harvest efficiency 

• darker green leaf color 

These benefits can provide for earlier maturity and often result in improved yields. 

Spray Coverage 

Under most circumstances, water is the recommended diluent, however, oil is pennitted in the 

following states for ultra low volume (UL V) aerial applications: Alabama, Arkansas, Florida, 

4 

Orig. EPA Approval 02102004 

Notification ~ storage&disposal~ 06122009 

8
( ( 

Georgia, Louisiana, Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, 

Tennessee, and Texas. Refer to Air and Ground Application sections for spray volumes. 

Regardless of method or gallonage of application, thorough coverage of the cotton foliage is 

required. 

Cleaning Application Equipment 

Clean application equipment thoroughly using a strong detergent or commercial sprayer cleaner 

according to the manufacturer's directions before and after applying this product, particularly if a 

product with the potential to injure crops was used. 

II. APPLICATION INSTRUCTIONS 

Early Application 

On both short-staple and Pima cotton, the grower has the option of low-rate multiple applications 

(see Table 1) or higher, less frequent dosages (see Table 2) which greatly facilitates his 

management flexibility. The multiple application option gives the producer the ability to 

discontinue usage ofMEP 42 if any significant stresses occur after an earlier application. In 

such a case, the total quantity ofMEP 42 used over a season may be reduced. If stress is 

relieved, the grower has the option of continuing treatments with MEP 42. In addition, the rate 

and timing ranges indicated in the Application Rates and Timings Tables allow the grower to 

tailor his usage ofMEP 42 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 section VII. General Restrictions and Limitations). 

Fields should be carefully scouted and MEP 42 sqould 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 made at 7-14 day intervals. However, if new growth 

at any time is excessive, higher rates ofMEP 42 can be used. If significant loss of squares or 

young bolls has occurred earlier due to insect pressure or other stresses, but now these stresses 

have all been alleviated, the need for MEP 42 is increased - excess vegetative growth is likely 

because of poor fruit load. 

Late Season Application 

Late application ofMEP 42 (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 ofMEP 42. Late season application 

can lead to one or more of the following: 

• reduction in late season vegetative growth or regrowth after cutout or defoliation 

• more complete and manageable cutout 

• better defoliation 

• earlier maturity 

• reduction in trash 

5 

Orig. EPA Approval 02102004 

NotifICation _ storage&disposal_ 06122009 

9
( 

• lower ginning costs 

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

season application ofMEP 42 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 ofpaor boll load 

and excellent growing conditions may not respond as much as desired to late season applications 

at the suggested rates. 

Timing for Late Season Applications 

• On fields where cotton cuts out 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 the first bloom. 

• On fields where cotton never completely cuts out: Apply MEP 42 when there are 4-6 nodes 

above the white flower (NA WF). Measure NAWF by counting the number of mainstem nodes 

from the first position white bloom (the one closest to the mainstem) to the tenninal. Count the 

node with the first position white bloom as zero and the last node in the terminal, which is 

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

nodes during the fourth to sixth week of bloom. 

During this time, the NA WF should be decreasing about one node every 5-6 days - if its 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 NAWF is still above 5-6, apply MEP 42. 

Use Rate for Late Season Application 

Apply 8-24 fluid ounces ofMEP 42 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. 

AIR APPLICATION 

Spray Volume 

• Water as Diluent: Use a minimum of2 gallons of water per acre in all states except 

California. In California, use a minimum of5 gallons of water 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 emulsifiers to provide good mixing quality. If the oil does not 

contain an emulsifier, one must be added during mixing at a volume equal to 3% of the final 

volume of the mixing tank. Do not apply MEP 42 ULV without using emulsifiers. Highly 

refined vegetable oils have proven more satisfactory than unrefined vegetable oils. For 

additional infonnation, see Compatibility Test for Mix Components.

AERIAL APPLICA nON METHODS AND EQUIPMENT 

Spray Drift Management 

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 agricultural field crops. These requirements do not 

apply to forestry applications, public health uses or to applications using dry fonnulations. 

I. 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 

downward more then 45 degrees. Where states have more stringent regulations, they 

should be observed. 

3. 

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. 

Importance of 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 the larger droplets reduces drift potential, but will not prevent drift if applications are 

made improperly, or under unfavorable environmental conditions (see Wind, Temperature and 

Humidity, and Temperature Inversion section of this label). 

Controlling Droplet Size 

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

higher rated flows produce larger droplets. Use a minimum of2 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 recommended 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 unifonn coverage. 

Nozzle Orientation - Orienting nozzles so that the spray is released backward, parallel to the 

airstream, 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 patterns. 

Boom Length - For some use patterns, reducing the effective boom length to less than % of the 

wingspan or rotor length may further reduce drift without reducing swath width. 

Application - Applications should not be made at a height greater than 10 feet above the top of 

the largest plants. Making applications at the lowest height that is safe reduces exposure of 

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 applicator must compensate for this 

displacement by adjusting the path of the aircraft upwind. Swath adjustment distance should 

increase, with increasing drift potential (higher wind, smaller drops, etc.). 

Wind 

Drift potential is lowest between wind speeds of2-10 mph. However, many factors, including 

droplet size and equipment type, determine drift potential at any given speed. Application 

should be avoided below 2 mph due to variable wind direction and high inversion potential. Do 

not apply lVIEP 42 by aircraft when wind is blowing more than 10 mph. Note: Local terrain can 

influence wind patterns. Every applicator should be familiar with local wind patterns and how 

they affect drift.

growth. 

Second Application for Control of Excessive Vegetative Growth: If the cotton 8-16 fluid 

field has a history of vigorous growth or if conditions after the first application of ounces 

MEP 42 favor vigorous growth, make a second application 2-3 weeks after the first 

application. 

Third Application for Control of Excessive Vegetative Growth: If the cotton field 8-16 fluid 

has a history of vigorous growth or if conditions continue to favor vigorous growth, ounces 

make a third application 1-2 weeks after the second application. 

Late Season Application: Referto Late Season Application in section II. 8-24 fluid 

Application Instructions. ounces 

Areas Where Excessive Vegetative Growth is Not a Problem 

First Application: Apply MEP 42 to actively growing cotton in the early bloom 8 fluid 

stage (5-6 blooms per 25 row feet). If no blooms are present and the cotton is 20" tall ounces 

and actively growing, apply MEP 42. 

Second Application: Ifconditions after the first application ofMEP 42 favor 8 fluid 

vigorous growth, make a second application 2-3 weeks after the first application. ounces 

Third Application: Ifconditions after the second application ofMEP 42 continue to 8 fluid 

favor vigorous growth, make a third application 1-2 weeks after the second ounces 

application.

Temperature and Humidity 

When making applications in low relative humidity, set equipment up to product larger droplets 

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

and dry. 

Temperature Inversions 

Applications should not occur 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 

and variable winds common during inversions. Temperature inversions are characterized by 

increasing temperatures with 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 indicated by ground fog; however, iffog is not present, inversions can also be 

identified by the movement of smoke from a ground source or an aircraft smoke generator. 

Smoke that layers and moves laterally in a connected cloud (under low wind conditions) 

indicates an inversion, while smoke that moves upwards and rapidly dissipates indicates good 

vertical air mixing. 

Sensitive Areas 

The pesticide should only be applied when the potential for drift to adjacent areas, (e.g. 

residential areas, bodies of water, known habitat for threatened or endangered species, nontarget 

crops) is minimal (e.g. when wind is blowing away from the sensitive areas). Do not apply MEP 

42 by air if sensitive species are within 200 feet. 

GROUND APPLICATION 

Spray Volume 

• Water as Diluent: Use 2 gallons of spray solution per acre in all states except California. In 

California, use a minimum of 5 gallons of spray solution per acre. 

ill. ADDITIVES 

Ifrain is expected within 8 hours, use a high-quality EPA-exempt surfactant to make MEP 42 

rain-safe after 4 hours. 

Compatibility Test for Mix Components 

Add components in the following sequence using 2 teaspoons for each pound or I teaspoon for 

each pint of recommended label rate per acre. 

I. Water - for 20 gallons per acre spray volume, use 3.3 cups (800 ml) of water. For other 

spray volumes, adjust rates accordingly. Use only water from the intended source at the 

source temperature. 

2. Products in PV A Bags - Cap the jar and invert 10 cycles. 

3. Water-Dispersible Products - (dry flowables, wettable powders, suspension 

concentrates, or suspo-emulsions) Cap the jar and invert 10 cycles. 

4. Water-Soluble Products - (such as MEP 42) Cap the jar and invert 10 cycles. 

5. Emulsifiable Concentrates - (oil concentrate) Cap the jar and invert 10 cycles. 

6. Water-Soluble Additives - Cap the jar and invert 10 cycles.

7. Let the solution stand for 15 minutes. 

8. Evaluate the solution for uniformity and stability. The spray solution should not have 

free oil on the surface, nor fine particles that precipitate to the bottom, not thick 

(clabbered) texture. Do not use any spray solution that could clog spray nozzles. 

IV. MIXING ORDER 

1. Water: Begin by agitating a thoroughly clean sprayer tank half full of clean water. 

2. Products in PV A Bags: Rinse the tank thoroughly before adding any material in PV A 

bags as boron residue will prevent adequate mixing. Place the water-soluble PV A bag 

into the mixing tank. The water-soluble PV A bag will dissolve in water to allow the 

contents to disperse. Wait until all water-soluble PYA bags have fully dissolved and the 

plant regulator is evenly mixed in the spray tank before continuing. 

To prepare spray solution for aerial application, use a mixing tank or mixing vat first to 

get the product into suspension before transferring suspension to air application 

equipment. 

3. Water-Dispersible Products: (dry flowables, wettable-powders, suspension 

concentrates, or suspo-emulsions). 

4. Water-Soluble Products 

5. Emulsifiable Concentrates 

6. Remaining quantity water. 

Only moderate agitation should be used while mixing and transporting. 

V. GENERAL TANK MIXING INFORMATION 

MEP 42 has an aqueous base, and as such, is compatible with most insecticides and miticides. 

You may combine MEP 42 with foliar fertilizers if prior experience has shown the original 

liquid formulation ofMEP 42 to be compatible and noninjurious under your conditions. Always 

perform a Compatibility Test for Mix Components before preparing a tank mix application. 

Read and follow the applicable Restrictions and Limitations and Directions for Use on all 

products involved in tank mixing. The most restrictive labeling applies to tank mixes. 

VI. GENERAL RESTRICTIONS AND LIMITATIONS 

• Maximum seasonal use rate: Do not apply more than a total of 48 fluid ounces (3 pints) of 

MEP 42 plant regulator (0.132 pounds a.i.) per acre, per season. 

• The sum of all products and formulations containing mepiquat chloride must not exceed 0.132 

pounds of mepiquat chloride per acre per season. 

• Preharvest Interval (PHI): Do not apply within 30 days of harvest. 

• Restricted Entry Interval (REI): 12 hours 

• Do not plant another crop within 75 days oflast treatment. 

• Stress: Do not apply to cotton plants under severe stress due to adverse weather conditions, 

mite, insect, or nematode damage, disease, herbicide injury, or fertility stress. If using the lowrate multiple option, discontinue use until the stress is alleviated. Do not apply a single 

application of 8-16 fluid ounces ofMEP 42 to cotton that is stressed due to lack of soil moisture.
