Abstract
Water dispersible solid granular agrochemical formulations, typically in the form of wettable powders, particularly having an average particle size from 5 to 50 &mgr;m, or water dispersible granules, particularly having an average particle size of from 200 &mgr;m to 5 mm, include one or more water dispersible agrochemical active components; and a dispersing agent including a water dispersible styrene (meth) acrylic copolymer. The copolymeric dispersing agent may include monomer residues which include strongly acidic, particularly sulphonic acid groups.
