Abstract

This invention relates to 'gelled-paste' compositions of sulfonylurea herbicides in a chemically stabilized formulation consisting essentially of a sulfonylurea or its agriculturally suitable salt with a salt of a carboxylic or an inorganic acid, or with mixtures of such carboxylic or inorganic acid salts in an aqueous medium and to the process for making such gelled-paste compositions, i.e., crop protection products. This invention also comprises an improved method of direct injection to crops of such crop protection products and an apparatus for the direct injection of said products.
