Herbicide delivery systems comprising a potassium salt of a herbicidal carboxylic acid coated onto a solid carrier.

Stable solid herbicide delivery systems

Methods of controlling undesirable vegetation comprising contacting the vegetation or the locus thereof with, or applying to the soil to control or prevent the emergence of the vegetation, a herbicidally effective amount of a herbicide delivery system.

Methods for using stable solid herbicide delivery systems

This invention relates to a high-strength, aqueous herbicidal concentrate containing the clopyralid dimethylamine salt. The formulation is stable to storage and exhibits lower viscosity than other clopyralid amine salt formulations.

High-strength, low viscosity herbicidal concentrate of clopyralid dimethylamin

Stable emulsifiable concentrates containing a first herbicidal carboxylic acid in the salt form and a second herbicidal carboxylic acid in the ester form are prepared by using a tertiary amine to prepare the salt of the first herbicidal carboxylic acid and by using an alcohol which is the same as the ester portion of the second carboxylic acid herbicide as the solvent.

Stable emulsifiable concentrates containing a first herbicidal carboxylic acid salt and a second herbicidal carboxylic acid ester

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.
