Compatibility agents for herbicidal formulations comprising 2,4-(Dichlorophenoxy) acetic acid salts

摘要

The present invention generally relates to a method for minimizing the formation of insoluble salts of phenoxy herbicides. The method comprises (1) mixing a compatibility agent, amine salts of phenoxy acid herbicides, and a chemical containing non-amine cations in a aqueous system to form a stable and non-nozzle plugging solution; and (2) application of said stable and non-nozzle plugging solution onto target plants.

主权项

1. A herbicidal formulation comprising (a) at least one amine salt of a phenoxy acid herbicide, (b) non-amine cations, and (c) at least one compatibility agent in an amount effective to prevent the formation of insoluble salts of said phenoxy acid herbicide,
wherein said compatibility agent comprises a substance selected from the group consisting of alkoxylated quaternary surfactant, alkyl quaternary surfactant, amidoamine, alkoxylate of the reaction product of fatty acid and polyamines, ethoxylate of the reaction product of fatty acid and triethanolamine, tristyrylphenol ethoxylate, EO-PO block or random copolymer, alkyl olefin sulfonate, alkylbenzenesulfonate amine salt, castor oil alkoxylate, sodium hydroxide, potassium hydroxide, ammonium hydroxide and combinations thereof, wherein the ratio of said at least one amine salt of a phenoxy acid herbicide to said compatibility agent is from 20:1 to 1:2 by weight, and wherein said herbicidal formulation does not comprise glyphosate.
