PURPOSE: A pesticide granule is provided, capable of slow releasing of the active component of pesticide. CONSTITUTION: A pesticide granule comprises an inner core and a coating layer, wherein the inner core comprises an active component of pesticide, a solid carrier, a binder and a water-soluble material which is a solid at room temperature and has a relative molecular mass of 50-700, and the water-soluble material is dispersed in the inner core. Preferably the solid carrier contains monmorylonite, or monmorylonite and carbon carbonate; the water-soluble material is urea and/or sugar; and the coating layer is a thermosetting resin. Preferably the ratio of the active component of pesticide: the solid carrier: the binder: the water-soluble material: the coating layer is 0.1-90: 0.5-95: 0.1-10: 4-50: 0.1-50 by weight. |
