PHOSPHATE ESTER-BASED SURFACTANT ADJUVANTS AND COMPOSITIONS THEREOF

摘要

Surfactants that further improve the bioefficacy of herbicides. The surfactants comprise (i) phosphate monoesters of tallow amine ethoxylates, alone or in combination with phosphate diesters of tallow amine ethoxylates, or (ii) alkoxylated phosphate monoesters of tallow amine ethoxylates, alone or in combination with alkoxylated phosphate diesters of tallow amine ethoxylates. The present invention also provides for herbicide compositions that contain the surfactants of the present invention. The herbicide compositions comprise a herbicidal active ingredient, a surfactant of the present invention, and optionally, one or more formulation aids. The herbicide compositions of the present invention are expected to ha ve a reduced tendency to cause eye and skin irritation. The present invention additionally provides for a method of controlling unwanted weeds or vegetation using the herbicide compo- sitions of the present invention.
