FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. The invention uses a copolymer containing, in polymerised form: a) N-vinylpyrrolidone and b) vinylimidazole or quaternised vinylimidazole as a dispersant in an aqueous composition containing a water-insoluble pesticide having solubility in water of up to 10 g/l at 20°C. The aqueous pesticide composition contains a copolymer containing, in polymerised form: a) at least 20 mol % N-vinylpyrrolidone and b) at least 1 mol % vinylimidazole or quaternised vinylimidazole; a water-insoluble pesticide having solubility in water of up to 10 g/l at 20°C; and a dissolved salt which dissociates in water at 20°C into at least one anion and one cation.

EFFECT: invention improves storage stability of the pesticide.
