FIELD: chemistry.
SUBSTANCE: invention relates to agriculture Pesticidal composition contains: organophosphoric pesticide and polymer, which forms capsule wall Capsule at least partly encapsulates organophosphoric pesticide, forming microcapsule, where wall has average thickness from approximately 5 nm to approximately 25 nm said microcapsule has average diameter in the range from approximately 2 mcm to approximately 6 mcm Term "approximately" supposes plus or minus 10% of the given value Organophosphoric pesticide is selected from the group, consisting of acephate, azinphos-methyl, chlorfenvinphos, clorethoxyphos, chlorpyriphos-methyl, diazinon, dimethoate, disulfoton, ethoprofos, fenitrothion, fenthion, fenamiphos, fosthiazate, malathion, methamidophos, methidathion, omethoate, oxydemethon-methyl, parathion, parathion-methyl, phorate, phosmet, profenofos and trichlorfon Wall is formed by interphase polycondensation of at least one poorly-soluble monomer, selected from the group, consisting of diisocyanates, polyisocyanates, chloroanhydrides of dibasic acids, chloroanhydrides of polybasic acids, sulphonyl chlorides and chloroformiates and at least one water-soluble monomer, selected from the group, consisting of: diamines, polyamines, water-soluble diols and water-soluble polyols Said composition is used to regulate the number of insects.
EFFECT: invention makes it possible to increase activity and reduce toxicity of composition.
