FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. The aqueous pesticide composition contains a) at least one pesticidal agent; b) polyvinyl alcohol (PVA); c) a graft copolymer and d) a plasticiser. The amount of the mixture of PVA and graft copolymer ranges from 1.0% to 3.0% by weight of the total amount of the preparation. The ratio of PVA to the graft copolymer ranges from 5:1 to 1.5:1 pts.wt. The aqueous pesticide composition contains a) at least one pesticidal agent; b) polyvinyl alcohol (PVA); c) a graft copolymer and d) a plasticiser. The amount of the pesticidal agent ranges from 35% to 50% by weight of the total amount of the composition. The amount of the mixture of PVA and graft copolymer ranges from 1.0% to 3.0% by weight of the total amount of the composition. The ratio of PVA to the graft copolymer ranges from 5:1 to 1.5:1 pts.wt. The amount of the plasticiser ranges from 7.0% to 12.0% by weight of the total amount of the composition. Compositions are applied for protection seeds from vermin.

EFFECT: invention improves adhesion properties and reduces toxicity of compositions.
