PROBLEM TO BE SOLVED: To produce a granulated water dispersible powder having character of suppressed evolution of powder dust, easy to measure as well as having a capability to contain an agrochemical in high concentration, and excellent in suspension stability and suppressed in phytotoxicity by adding specific metal oxides to an agrochemical as an active ingredient. SOLUTION: One or more kinds of metal oxides selected from zinc oxide, aluminum oxide, titanium oxide, ferric oxide, copper oxide, nickel oxide and manganese oxide are added to an agrochemical as an active ingredient. Acephate, Nitenpyram, Cartap hydrochloride, Validamycin A and Bensultap are preferred as the active ingredient. The preferred content of the agrochemical as the active ingredient is more than 70wt.% based on total preparation. The preferred average particle size of metal oxide is about 0.01-15μm. Titanium oxide is especially preferred as the metal oxide. A surfactant and/or a binder may be added to this mixture. The granulated water dispersible powder having a bulk density of about 0.1-1.2g/ml is especially preferred. |
