PROBLEM TO BE SOLVED: To provide an agrochemical granule containing an agrochemically active ingredient having high water solubility, capable of controlling the release of an agent for a long period, while keeping sufficient release efficiency of the agent, and to provide a prescription and production method of the agrochemical granule having also economical efficiency of production enough for industrial production by improving granulation efficiency.SOLUTION: An agrochemical granule composition contains an agrochemically active ingredient (A) whose water solubility at 20°C is &ge100 ppm, one or two or more kinds of mixtures (B) selected from among 8-40C alkyl chain carboxylic acid and derivatives thereof, an inorganic material (C), and a petroleum fraction (D) which is a liquid at room temperature and has a boiling point of &ge200°C at a normal pressure. In the agrochemical granule formed by granulating the composition, excellent granulation efficiency can be obtained, and the release of the agrochemically active ingredient having high water solubility can be controlled for a long period.COPYRIGHT: (C)2012,JPO&INPIT【課題】水溶性の高い農薬活性成分を含有する農薬粒剤において、十分な薬剤の溶出効率を保ちつつ薬剤の溶出を長期間維持できるものを提供することにある。さらに、造粒効率を向上させて、工業的製造に耐え得る生産経済性を併せ持つ農薬粒剤の処方及び製造方法を提供することにある。【解決手段】20℃における水溶解度が100ppm以上の農薬活性成分(A)、C8~C40アルキル鎖カルボン酸及びその誘導体の中から選ばれる1種又は2種以上の混合物(B)、無機物質(C)、常温液体かつ常圧で200℃以上の沸点を有する石油留分(D)を含有する農薬粒剤組成物が、これを造粒して成る農薬粒剤において、良好な造粒効率が得られると共に、水溶解度の高い農薬活性成分を長期間に亘り溶出を制御できることを見出した。【選択図】なし
