Abstract:
1. A method to reduce the eye irritancy caused by exposure to aqueous herbicidal concentrates of commonly used ammonium salts of auxinic carboxylic acids derived from mono-, di- or trialkylamines, comprising preparing aqueous herbicidal concentrates that include N,N,N-trimethylethanolammonium cations as the ammonium salt of auxinic carboxylic acids selected from benzoic acid herbicides, pyridine carboxylic acid herbicides, pyridinyloxyacetic acid herbicides, phenoxyacetic acid herbicides, phenoxybutyric herbicides, and phenoxypropionic herbicides, wherein the aqueous herbicidal concentrates containing N,N,N-trimethylethanolammonium cations provide reduced eye irritation compared to the commonly used ammonium salts of auxinic carboxylic acids.
