FIELD: agriculture. n SUBSTANCE: invention relates to agriculture, in particular to agrochemical compositions. Insecticidal composition contains an aqueous phase and dispersed therein multiple microcapsules, each contains at least one organophosphate insecticide, for example, chlorpyrifos-methyl, at least partially surrounded by polymer shell. Polymer shell is formed from a mixture containing cross-linked amine and isocyanate, where the molar ratio of amine groups in cross-linked amine to isocyanate groups in izocianate is between 0.3:1 and 0.7:1. Insecticide compositions may be used for control of insect population by single or regular applications. n EFFECT: disclosed insecticide compositions have improved chemical and physical stability. n 29 cl, 1 dwg, 8 tbl,4 ex |
