  • Patent number: 8044059
    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.
