Abstract
The use of an N,N-dimethyl alkylamide or an N-alkanoyl morpholine provides a stable emulsifiable concentrate composition that hinders de-esterification and transesterification of mixtures of a carboxylic acid herbicide and an ester of a different carboxylic acid herbicide. The N,N-dimethyl alkylamide or N-alkanoyl morpholine additionally stabilizes emulsifiable concentrates containing a triazolopyrimidine herbicide having at least one methoxy group on the triazolopyrimidine ring.
Claims10
A method to provide a stable emulsifiable concentrate composition containing a mixture of a free acid of a carboxylic acid herbicide and an ester of a different carboxylic acid herbicide by hindering de-esterification and transesterification which comprises incorporating into the composition from about 10 to about 600 grams/liter (g/L) of an N,N-dimethyl (C6-C12)alkyl amide or an N—(C5-C11)alkanoyl morpholine.
A method to provide a stable emulsifiable concentrate composition containing a triazolopyrimidine herbicide having at least one methoxy group on the triazolopyrimidine ring in admixture with a free acid of a carboxylic acid herbicide and/or an ester of a carboxylic acid herbicide by hindering degradation of the methoxy group to an hydroxy group which comprises incorporating into the composition from about 10 to about 600 g/L of an N,N-dimethyl (C6-C12)alkyl amide or an N—(C5-C11)alkanoyl morpholine.
A stable emulsifiable concentrate composition comprising a) from about 5 to about 500 g/L of a carboxylic acid herbicide as a free acid, b) from about 10 to about 700 g/L of a different carboxylic acid herbicide as an ester, c) from about 10 to about 600 g/L of an N,N-dimethyl (C6-C12)alkyl amide or an N—(C5-C11)alkanoyl morpholine, and d) from about 60 to about 720 g/L of an organic solvent and surfactants.
A stable emulsifiable concentrate composition comprising a) from about 1 to about 5 g/L of a triazolopyrimidine herbicide having at least one methoxy group on the triazolopyrimidine ring, b) from about 5 to about 700 g/L of a carboxylic acid herbicide as a free acid and/or an ester of a carboxylic acid herbicide, c) from about 10 to about 600 g/L of an N,N-dimethyl (C6-C12)alkyl amide or an N—(C5-C11)alkanoyl morpholine, and d) from about 60 to about 720 g/L of an organic solvent and surfactants.
