摘要：
1. A stable solid pesticidal composition which comprises: 1) a microcapsule, comprising (a) a water-insoluble thin-walled shell of polyurea which is prepared by interfacial polycondensation reaction of a water-soluble monomer and an oil-soluble polyamine polyisocyanate monomer, and (b) a core comprising a low melting active ingredient, wherein (i) the ratio of amine moieties to isocyanate moieties is approximately 1: 1 (ii) the thickness of the polyurea shell is greater than about 10 nm and less than about 60 nm (iii) the average size of the microcapsules is from about 1 microns to about 25 microns, (iv) the mass ratio of core to shell of polyurea is from about 2 to about 165 and (v) a microcapsule is present in an amount of about 300 g / kg to about 900 g / kg of the total weight of the composition, 2) a solid water soluble polymer stabilizer is present in an amount of from about 5 g / kg to about 250 g / kg of total weight of the composition and 3) ability to emulsify the solid or dispersible solid surfactant, which is present in an amount of from about 5 g / kg to about 300 g / kg of the total weight kompozitsii.2. Composition according to Claim. 1, wherein the water soluble polyamine is a diamine monomer and an oil-soluble monomer is a polyisocyanate diizotsianat.3. The composition of claim. 1, wherein the active ingredient is a low-melting-meptil fluroxypyr, benfluralin, trifluralin, ethalfluralin, cyhalofop, cyhalofop-butyl, clodinafop, dithiopyr, fenoxaprop, hair dryer
