KADUSAFOS MICROCAPSULATED COMPOSITIONS Russian patent published in 2004 - IPC

FIELD: pesticides. SUBSTANCE: invention relates to producing pesticides. Method involves carrying out the following stages: a) formation of an aqueous phase comprising one or some emulsifying agents and an anti-foaming agent; b) formation of kadusafos-containing phase not mixing with water and isocyanate monomer; c) emulsification of phase not mixing with water in an aqueous phase to form dispersion of drops not mixing with water in an aqueous phase; d) addition to dispersion of an aqueous solution of one or more poly-functional amine taken in the amount that is effective for providing interphase polymerization with isocyanate monomer to form kadusafos microcapsules. Invention relates to a pesticide composition prepared by this method. Kadusafos pesticide composition comprises an aqueous suspension of microcapsules that have envelope prepared of polyurea surrounding a kadusafos- -containing core. Envelope is formed by interphase polymerization of isocyanate and one or some poly-functional amines and envelope is not penetrable for kadusafos and components of pesticide have a granulated composition. Invention provides reducing toxicity of the end product. EFFECT: valuable properties of compositions. 14 cl, 10 tbl, 7 ex
