摘要： A microencapsulated agricultural chemical comprises an agricultural chemical as an active ingredient having a solubility of not more than 1 g in 100 ml of water at 20.degree. C. and vapor pressure of not more than 760 mmHg at 60.degree. C. and a microcapsule wall enclosing the agricultural chemical therein and the microcapsule wall comprises a water-soluble cationic urea resin and at least one of prepolymer composed of formaldehyde and at least one compound selected from the group consisting of urea, melamine and thiourea. The microcapsule is prepared by dispersing the agricultural chemical in an aqueous medium containing the water-soluble cationic urea resin, an anionic surfactant and at least one of the prepolymer and maintaining pH of the obtained dispersion within an acidic range to polycondense the water-soluble cationic urea resin and at least one of the prepolymers.

摘要： The invention relates to a process for the preparation of microcapsules of organo-phosphoric acid derivative as capsule core. The derivative has a partial mutual solubility with water. The main feature of the invention is the provision of an inner provisional solid capsule shell of a high molecular hydrophobic substance, such as polymethyl methacrylate. This substance is liable to form a shell on each of the droplets by sedimenting under aqueous condition, while it is capable of dissolving into the capsule core substance, when subject to non-aqueous condition which is established after formation of a permanent outer shell on the provisional shell of each capsule. The provisional shell-forming substance is polymethyl methacrylate, polystyrene, polyvinyl chloride or polyvinyl acetate.
