水溶性殺虫剤を内包するマイクロカプセル化農薬製剤の開発  [in Japanese] PREPARATION AND CHARACTERISTICS OF MICROCAPSULE ENCAPSULATED WATER-SOLUBLU PESTICIDE  [in Japanese]

The microcapsules with water-soluble pesticide were prepared by in situ polymerization and solvent evaporation of water-in-oil-in-water emulsion. Trimethylolpropane trimethacrylate (TRIM) and acetamiprid were used as a wall material and water-soluble pesticide, respectively. The capsule morphology, entrapment rate of pesticide, and control released profile were evaluated in detail. The microcapsules were successfully prepared with well-defined spherical property, 50-150μm diameter, and 4.2% entrapment rate. The water-soluble pesticide entrapment rate, 4.2%, of the microcapsules was two times compared to that of the commercial available agrochemical material entrapped the same pesticide. In the controlled release experiment, the controlled release profile exhibited the similar behavior toward the commercial one.
