摘要
The first invention, and contains at least one agrochemical active ingredient as the active ingredient, the coating pesticide particles, and the pesticide particles, characterized in that at least even circular again obtained by calculation, shown in the formula coefficient of 0.7, the resin the coated agricultural chemical granule covered with a coating film containing as a main component.; The circularity coefficient = (4π × projected area of particle) / (length of the outline of the particle projection) 2; The second invention, the swelling power is 1~30 mL / 2g of the pesticide particles when the absorption, is a time limit controlled release coated pesticide granules coated with a thermoplastic resin as a film material, as an active ingredient. The agricultural chemical granule is, has an excellent initial discharge suppression, and the initial dissolution stability function.
