PROBLEM TO BE SOLVED: To provide a granular agrochemical composition capable of adequately controlling sustained release performance of an agrochemically active compound, and to provide a method for producing the same.SOLUTION: The coated granular agrochemical composition is obtained by solidifying and coating a powdery agrochemical composition with a thermosetting resin. The method for producing the coated granular agrochemical composition comprises: a step of mixing the powdery agrochemical composition with a first liquid material serving as a raw material for the thermosetting resin a step of adding a second liquid material serving as a raw material for the thermosetting resin to the mixture obtained in the previous step a step of obtaining a granular agrochemical by reacting the first liquid material with the second liquid material to yield the thermosetting resin and a step of simultaneously or successively adding the first liquid material and the second liquid material to the granular agrochemical obtained in the previous step, reacting the first liquid material with the second liquid material and coating the resultant granular agrochemical with the thermosetting resin.COPYRIGHT: (C)2013,JPO&INPIT【課題】農薬活性化合物の徐放性能を適宜調整することが可能な、粒状農薬組成物及びその製造方法を提供すること。【解決手段】粉状農薬組成物が熱硬化性樹脂で固められ被覆されてなる被覆粒状農薬組成物;並びに、粉状農薬組成物と熱硬化性樹脂の原料となる第1液状原料とを混合する工程、前工程で得られた混合物に熱硬化性樹脂の原料となる第2液状原料を添加する工程、該第1液状原料と該第2液状原料とを反応させて熱硬化性樹脂を生成させることで粒状農薬を得る工程、及び前工程で得られた粒状農薬に熱硬化性樹脂の原料となる第1液状原料と第2液状原料とを同時又は順次加え、該第1液状原料と該第2液状原料とを反応させて、該粒状農薬を熱硬化性樹脂で被覆する工程を有する被覆粒状農薬組成物の製造方法。【選択図】なし
