§ 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 （C10C18） as a surfactant in emulsifier blends that are added to the herbicide atrazine for application to corn.
α-（ 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.
α-[ 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.
α-[ 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 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.
