GENERAL INFORMATION
FOLEX 6 EC is a cotton defoliant that is used to remove leaves from cotton plants prior to anticipated harvesting.
Formulated as an emulsifiable concentrate, FOLEX 6 EC contains 6 pounds active ingredient per gallon. FOLEX 6 EC is most commonly mixed with water and applied to cotton using either ground or aerial equipment. However, diesel oil may be substituted for water under adverse weather conditions. Folex is non-corrosive and will not damage metal pa.ts normally used in applying spray chemicals.
FOLEX 6 EC usually drops leaves in a green condition and will not appear effective until defoliation actually begins, approximately 3 days after application. By this time, the field will have an "off-cast" color. Under favoratable conditions, satisfactory leaf drop will require 5 to 7 days. Adverse conditions, such as low temperatures and/or toughened plants (drought stressed, etc.) may extend this to 10 to 14 days.
FOLEX 6 EC is effective when applied to cotton with a heavy dew. Once FOLEX 6 EC has dried on the leaf subsequent rainfall or dew does not adversely affect its activity. Application of FOLEX 6 EC is i.ot recommended when a heavy rainfall is expected within 1 hour after treatment. Conditions which delay absorption in'c the leaves are primarily those which cause the cotton leaves to be wilted, toughened, or leathery. When these conditions prevail, use diesel oil instead of water. FOLEX 6 EC does not suppress second growth especially where rainfall follows defoliation. A second application of FOLEX 6 EC will be effective in defoliation of this second growth if excessive regrowth occurs between the first application and first and/or second harvest. FOLEX 6 EC must be applied in sufficient water or diesel oil to give thorough coverage of the leaves. Larger droplets more effectively reach the lower leaves.
Use the higher FOLEX 6 EC rate under conditions of low temperature, low humidity, or plant stress.
FOLEX 6 EC may be used alone for bottom defoliation of the leaves on lower portion of the plant as a preconditioner prior to total defoliation, or as a total defoliation treatment. FOLEX 6 EC may also be used in combination with Dropp (tank mix).
IMPORTANT: Observe all cautions and limitations on labels of all products used in mixtures specifically when FOLEX 6 EC is tank mixed with products for use on cotton in areas where citrus is grown. Observe buffer zones and other restrictions on the FOLEX 6 EC label and/or in the manufacturer's recommendations for Folex.

MIXING INSTRUCTIONS
FOLEX ALONE: Fill the spray tank 1/2 to 3/4 full with clean water. Begin agitation and add the recommended amount of FOLEX 6 EC. Add water to the spray tank to the desired level. Maintain sufficient agitation to ensure a uniform spray mixture during application. Follow same mixing instructions when diesel oil is substituted for water.

TANK MIXTURES: Fill the spray tank 1/2 to 3/4 full with clean water and begin agitation. When tank mixing with Dropp, add the recommended amount of Dropp first. After Dropp is thoroughly mixed with water, add the recommended amount of FOLEX 6 EC. Add water to the spray tank to the desired level. Maintain sufficient agitation while mixing and during application to ensure a uniform spray mixture. If spray mixture is allowed to remain without agitation for short periods of time, be sure to agitate until uniformly mixed before application. Do not use diesel oil when Folex is used in a tank mixture with other products. For boll opening and defoliation, see below.

COMPATIBILITY: To determine the compatibility of FOLEX 6 EC with other products, do the following: (1) pour the recommended proportions of the products into a suitable container of water, (2) mix thoroughly and (3) allow to stand at least five minutes. If the combination remains mixed or can be re-mixed readily, it is considered physically compatible. For further information contact your local AMVAC Representative.

ADDITION OF ADJUVANTS: To improve spray coverage, FOLEX 6 EC may be applied with the following adjuvants: (1) commercial blends of vegetable or petroleum-based oils, (2) non-ionic surfactant and (3) diesel oil (if allowed by local regulations). Diesel oil (3 to 5 gallons by air or 5 to 10 gallons by ground) may be helpful when night temperatures drop below 60°F, plants are under moisture stress or on storm-proof cotton varieties.
Only adjuvants which are exempt from tolerance requirements under 40 CFR 180.1001 may be used. Test the compatibility of FOLEX 6 EC plus Dropp 50WP with the selected adjuvant prior to mixing in the spray tank (see compatibility section).

DOSAGE: Use the specified dosage of FOLEX 6 EC in water or once refined vegetable oil (see Recommended Applications Table) or diesel (see ADDITIONS OF ADJUVANTS). Apply sufficient spray to ensure uniform leaf wetting. All leaves must be treated for complete defoliation. FOLEX 6 EC does not suppress secondary growth.

SPRAY EQUIPMENT CLEANING AND DECONTAMINATION
Do not allow pesticide mixtures to dry in spray equipment. Dried pesticides residues may become resuspended and damage other crops if uncleaned spray equipment is used to apply other products during the same or following year.
Thoroughly clean the spray equipment with a chemical cleaner before using for other products. Use a cleaner such as "Spic and Span", "Fantastic", or "Formula 409". If chlorate type chemicals have been used in the same spiay equipment, thoroughly wash spray tank and particularly dried deposits on aircraft fabric. Immediately after applying FOLEX 6 EC, remove all unused spray mixture and follow directions,on this label for disposal. Thoroughly clean the spray tank, lines, nozzles, and exterior surfaces of spray equipment. Use one of the cleaners listed above. Follow directions on this label for disposal of wash and rinse water.

APPLICATION PROCEDURES
Do not apply FOLEX 6 EC through any type of irrigation system.
FOLEX 6 EC alone and in a tank mixture with Dropp can be applied by both ground and aerial equipment.

GROUND APPLICATION
Use a standard high clearance sprayer that provides a uniform accurate application. Sprayer should be equipped with screens no finer than 50 mesh in the nozzle tips and in-line strainers. A minimum spray volume of 10 gallons per acre is recommended when FOLEX 6 EC is applied with water and a minimum of 5 gallons per acre is recommended when FOLEX 6 EC is applied with diesel oil.
Do not allow sprays to drift from the application site and contact people, structures people occupy at any time and nontarget crops, aquatic and wetland areas, woodlands, pastures, rangelands, or animals.
For ground rig applications, apply product no more than 4 feet above the ground or the crop canopy and only when wind speed in 10 mph or less at the application site as measured by an anemometer.

AERIAL APPLICATION
Use aerial equipment equipped with a diaphragm-type nozzle that produces cone spray patters with a maximum spray pressure of 40 psi at the nozzle tips. Nozzles should be located no farther than 3/4 the distance from the center of the aircraft to the end of the wing or rotor. The aircraft should discharge the spray a maximum of 10 feet above the crop.
Do not apply when winds may cause drift to adjacent fields.
A minimum spray volume of 5 gallons per acre should be used when FOLEX 6 EC and tank mixtures with FOLEX 6 EC are applied with water. FOLEX 6 EC alone may be applied in a minimum of 3 gallons of spray volume per acre when using diesel oil (minimum of 5 GPA in California).
Aerial applicators must be in enclosed cockpits.
Aerial Drift Reduction Advisory: Avoiding spray drift at the application site is the responsibility of the applicator.
The interactions 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.
1. The distance of the outer most nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor.
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 should be observed. The applicator should be familiar with and take into account the information covered in the Aerial Drift Reduction Advisory information.

Information on 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 will not prevent drift if applications are made improperly, or under unfavorable environmental conditions (see Wind, Temperature and Humidity, and Temperature Inversions).

Controlling Droplet Size
Volume: Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger droplets.
Pressure: Do not exceed the nozzle manufacturer's recommended pressures. For many nozzle types lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure.

Number of Nozzles: Use the minimum number of nozzles that provide uniform coverage.
Nozzle Orientation: Orienting nozzles so that the spray is released parallel to the airstream pro Jutes larger droplets than other orientations and is the recommended practice. Significant deflection from 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 the largest droplets and the lowest drift.

Boom Length
For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or rotor length may further reduce drift without reducing swath width.


Application Height
Applications should not be made at a height greater than 10 feet above the top of the largest plants unless a greater height is required for aircraft safety. 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 crosswind, 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 of 2-10 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. NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray 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
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 variable winds common during inversions. Temperature inversions are characterized by increasing temperatures with altitudes 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, if fog 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 concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing.
Sensitive Areas
The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g. when wind is blowing away from the sensitive areas).
