FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. The agrochemical composition contains microcapsules. The active ingredient in the capsules is selected from a group comprising chlorpyrifos, fluroxypyr, diflufenican, sulphonylurea and mixtures of diflufenican with sulphonylureas, fluroxypyr with sulphonylureas, chloropyrifos with sulphonylureas, chlorpyrifos with fluroxypyr, fluroxypyr with diflufenican, or is selected from a group comprising triazole fungicides, and mixtures with fluroxypyr and/or chlorpyrifos. In case of mixtures, at least one of the active ingredients is microencapsulated. The microcapsules have size of 1-30 mcm. The shell of the microcapsules is made from polyurea which is formed during reaction of an aromatic isocynate and mono-, di-, tri- or tetra-alkoxyalkylglycoluril, where alkoxy denotes methoxy, ethoxy or isopropoxy, and alkyl denotes methyl, ethyl or isopropyl. The agrochemical composition contains 1-45 wt % styrene acrylic polymer. The reaction of materials which form the shell takes place in aqueous phase. The agrochemical composition is used against fungi, weeds and/or insects.

EFFECT: invention increases stability of the composition.
