Sec.  172.710  Adjuvants for pesticide use dilutions.


    The following surfactants and related adjuvants may be safely added 
to pesticide use dilutions by a grower or applicant prior to application 
to the growing crop:

    n-Alkyl (C8-C18) amine acetate, where the 
alkyl groups (C8-C18) are derived from coconut 
oil, as a surfactant in emulsifier blends at levels not in excess of 5 
percent by weight of the emulsifier blends that are added to herbicides 
for application to corn and sorghum.
    Di-n-alkyl (C8-C18) dimethyl ammonium 
chloride, where the alkyl groups (C8-C18) are 
derived from coconut oil, as surfactants in emulsifier blends at levels 
not in excess of 5 percent by weight of emulsifier blends that are added 
to herbicides for application to corn or sorghum.
    Diethanolamide condensate based on a mixture of saturated and 
unsaturated soybean oil fatty acids (C16-C18) as a 
surfactant in emulsifier blends that are added to the herbicide atrazine 
for application to corn.
    Diethanolamide condensate based on stripped coconut fatty acids 
(C10 C18) as a surfactant in emulsifier blends 
that are added to the herbicide atrazine for application to corn.
    [alpha]-(p-Dodecylphenyl)-omega-hydroxypoly (oxyethylene) produced 
by the condensation of 1 mole of dodecylphenol (dodecyl group is a 
proplyene tetramer isomer) with an average of 4-14 or 30-70 moles of 
ethylene oxide; if a blend of products is used, the average number of 
moles of ethylene oxide reacted to produce any product that is a 
component of the blend shall be in the range of 4-14 or 30-70.
    Ethylene dichloride.
    Polyglyceryl phthalate ester of coconut oil fatty acids.
    [alpha]-[p-(1,1,3,3-Tetramethylbutyl) phenyl]-omega-
hydroxypoly(oxyethylene) produced by the condensation of 1 mole of p-
(1,1,3,3-tetramethylbutyl) phenol with an average of 4-14 or 30-70 moles 
of ethylene oxide; if a blend of products is used, the average number of 
moles of ethylene oxide reacted to produce any product that is a 
component of the blend shall be in the range of 4-14 or 30-70.
    [alpha]-[p-(1,1,3,3-Tetramethylbutyl) phenyl]-omega-
hydroxypoly(oxyethylene) produced by the condensation of 1 mole of p-
(1,1,3,3-tetramethylbutyl) phenol with 1 mole of ethylene oxide.
    Sodium acrylate and acrylamide copolymer with a minimum average 
molecular weight of 10,000,000 in which 30 percent of the

[[Page 73]]

polymer is comprised of acrylate units and 70 percent acrylamide units, 
for use as a drift control agent in herbicide formulations applied to 
crops at a level not to exceed 0.5 ounces of the additive per acre.
