NOVELTY - Method for preparing silicone-containing pesticide microcapsule, involves (a) dissolving gelatin and anionic silicone surfactant in water to obtain solution (A), (b) dissolving sodium carboxymethyl cellulose in water to obtain solution (B), and adding solution (B) to the solution (A) to obtain solution (C), (c) mixing e.g. pesticidal suspension, gelatin and anionic silicone surfactant with the solution (C), (d) adding acid and water, performing coacervation reaction, cooling, and performing crosslinking process, and (e) adding alkali solution and processing mixture.    USE - The method is useful for preparing silicone-containing pesticide microcapsule (claimed).    ADVANTAGE - The method is environmentally-friendly and cost-effective, and utilizes silicone having high chemical stability and low surface tension, which improves spreading ability of pesticide with respect to foliage of plants, thus utilization rate of pesticide is improved, and prolongs persistence of pesticide.    DETAILED DESCRIPTION - Method for preparing silicone-containing pesticide microcapsule, involves (a) mixing gelatin and anionic silicone surfactant in a mass ratio of 0.5-10:1, and dissolving obtained mixture in water at 20-60?oC to obtain solution (A), (b) dissolving sodium carboxymethyl cellulose in water at 70-90?oC to obtain solution (B), and adding solution (B) to the solution (A) to obtain solution (C) comprising sodium carboxymethyl cellulose and gelatin in a mass ratio of 0.05-1:1, (c) mixing pesticidal suspension, gelatin, sodium carboxymethyl cellulose and anionic silicone surfactant with the solution (C) in a mass ratio of 0.20-10:1, and stirring obtained solution for 1-100 minutes to obtain oil/water (O/W)-type emulsion, (d) adding acid and water to the oil/water (O/W)-type emulsion, performing coacervation reaction, cooling obtained product to 0-15?oC, performing crosslinking process by adding crosslinking agent to the product, and continuing reaction for 2-20 hours, and (e) adding alkali solution to product obtained in step (f), regulating pH of obtained mixture at 7-12, and heating the mixture at 30-60?oC for 1-3 hours to obtain product.
