APPLICATION
DEFOL 750 may be applied by aircraft or ground equipment. It is essential that the foliage be thoroughly 
covered. The specified dilution rates should be carefully observed. A non-ionic surfactant such as Surf-Ac®
820 or an emulsifiable crop oil such as Peptoil™ may enhance the results. This product should not be mixed 
with insecticides or other organic materials, unless specifically recommended, because a fire or explosion 
may result. 
Precautions should be taken to avoid having spray or spray drift contact adjacent crops or desirable 
vegetation or they may be defoliated. Equipment should be washed before and after use and care should 
be taken so that product does not dry in tank or on spray nozzles. Washwater should not be allowed to 
contact desirable vegetation. 
When using this product under dry land conditions, injury may occur to rotational crops. 
SPRAY DRIFT MANAGEMENT 
A variety of factors including weather conditions (e.g., wind direction, wind speed, temperature, relative 
humidity) and method of application can influence pesticide drift. The applicator must evaluate all factors 
and make appropriate adjustments when applying this product. 
Wind Speed 
Do not apply at wind speeds greater than 15 mph. 
Droplet Size 
Apply as a medium or coarser spray (ASAE Standard 572). 
Temperature Inversions 
If applying at wind speeds less than 3 mph, the applicator must determine if: a) conditions of temperature 
inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. 
Do not make applications into areas of temperature inversions or stable atmospheric conditions. 
Other State and Local Requirements 
Applicators must follow all state and local pesticide drift requirements regarding application of sodium 
chlorate. Where states have more stringent regulations, they must be observed. 
Equipment
All application equipment must be properly maintained and calibrated using appropriate carriers or 
surrogates. 
Additional Requirements for Aerial Applications 
1. The boom length must not exceed 75% of the wingspan or 90% of the rotor blade diameter. 
2. Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a 
height greater than 10 feet above the crop canopy unless a greater height is required for aircraft safety. 
3. When applications are made with a crosswind, the swath must be displaced downwind. The applicator 
must compensate for this displacement at the up and downwind edge of the application area by adjusting 
the path of the aircraft upwind. 
Additional Requirement for Groundboom Application 
Do not apply with a nozzle height greater than 4 feet above the crop canopy. 
DEFOLIATION 
Ideally, defoliation is favored on clear, calm, sunny days with high temperatures and high humidity. If rain 
is anticipated within 24 hours, application should be delayed whenever possible. Defoliation may be slowed 
when daytime temperatures are below about 60°F and with some crops, especially with vigorous varieties, 
regrowth can occur. 
In order to obtain acceptable defoliation results, the crop must be fully mature. In most cases, the signs of 
maturity include: 
1. A slight discoloration of the foliage is apparent, often with a yellowish or reddish tinge. 
2. Vegetative growth has slowed or ceased, with little or no secondary growth. 
3. A slight downward pull on a leaf gives a clean break from the stalk.

Page4of7

Adequate fertility, ample soil moisture, good insect control and good weed control also favor defoliation. 
Plants which have been under stress as from drought or insect pressure give less reliable results because 
tough, wilted or damaged leaves do not permit the proper uptake of the chemical and tend to inhibit the 
formation of an abscission layer. Typically, under such circumstances, the leaves are desiccated but do not 
drop, which in turn, often causes problems with excessive trash during harvesting. 
For crops where there is a heavy canopy of foliage, obtaining thorough coverage is sometimes difficult. 
Whenever practical, the use of ground equipment should be considered. The higher dilution rates should 
be used and any other available methods employed which will assure that the plants are completely covered 
all the way to the bottom leaves. If coverage is incomplete, a second application may be necessary in order 
to defoliate the lower leaves and to prevent secondary growth. 
DESICCATION 
When the objective is to reduce crop moisture or to desiccate weeds prior to harvest, most of the points 
discussed under “DEFOLIATION” are applicable. Incomplete coverage will give erratic results, especially 
with vines such as Morningglory where the slender stems may be sheltered from the spray by the crop 
canopy, leaving the vines succulent and tough so they will become entangled in the harvesting machinery. 
Once again, larger spray volume will encourage more complete coverage and more reliable desiccation. 
CROPS 
Crop Rate Per Acre (qts.) Water (gals.) 
Chili peppers 1.6 to 4 Air: 5 to 15 
Ground: 20 to 40 
SPECIFIC DIRECTIONS: Apply 10 days before harvest. To be used on Peppers for processing only. 
Consult a processor before applying. 
Corn 3.2 Air: 5 to 7 
Ground: 10 to 20 
SPECIFIC DIRECTIONS: Use as a harvest aid to desiccate trashy weeds in early maturing Corn. Apply 
at least 14 days before anticipated harvest date. Use the low dilution rates when weeds are small and 
the crop canopy is fairly open. Desiccation of Morningglory and other vines may be erratic. DO NOT 
graze treated fields or feed fodder, forage or residual grain within 14 days of application. 
Cotton 1.6 to 3.2 Air: 5 to 10 
Ground: 10 to 20 
SPECIFIC DIRECTIONS: Apply no later than 7 days before harvest. The Cotton plants should be mature 
with the youngest bolls expected to make Cotton being at least 30 days old. Thorough coverage is 
essential. DO NOT graze treated fields or feed gin waste to livestock. DO NOT apply more than 3.2 
quarts per acre per application. A maximum of one application per year is permitted, except in California, 
where a maximum of two applications per year is permitted. 
Dry beans 3.2 Air: 5 to 10 
Ground: 10 to 20 
SPECIFIC DIRECTIONS: Thorough coverage is essential. Make application 7 to 10 days before 
anticipated harvest, longer if temperatures are cool. DO NOT graze treated fields or feed treated fodder 
or forage to livestock. 
Flax 3.2 Air: 5 (min.) 
Ground: 10 (min.) 
SPECIFIC DIRECTIONS: Use as a harvest aid to desiccate trashy weeds and to reduce moisture in the 
mature crop. Apply 7 to 10 days before anticipated harvest date. Activity of the spray will be enhanced 
by addition of a good non-ionic surfactant at the rate of 1 quart per 100 gallons of spray. DO NOT graze 
treated fields or feed treated foliage and fodder for 14 days after application.
