A method of producing a granular agrochemical composition having excellenthandling properties, wherein a powdered agrochemical wettable composition orpowdered agrochemical water-soluble composition is converted in form to agranularagrochemical composition, without altering the formulation thereof. The methodofproducing a granular agrochemical composition includes: treating a powderedagrochemical wettable composition or powdered agrochemical water-solublecomposition by (1) a step of adding water, kneading, extruding and drying, (2)a step ofadding water, granulating by stirring and drying, (3) a step of adding water,kneading andspray-drying, (4) a step of adding Water and performing fluidized bedgranulation, or (5)a step of pressure molding the powdered agrochemical wettable composition orpowdered agrochemical water-soluble composition; followed by (a) a step ofperformingmicrogranulation by grinding, and if necessary, (b) a step of performing grainsizeregulation by sieving.
