Zusammenfassung:PURPOSE:To provide a stable wettable powder composition of practical use, having decomposition resistance and low agglomeration tendency, by adding anhydrous silicon oxide to a wettable powder containing O,O-dimethyl-N-methylcarbamoylmethyl dithiophosphate. CONSTITUTION:The objective wettable powder composition is prepared by adding one or more agents such as aerosil 130, aerosil 200, aerosil 300, etc. obtained e.g. by the thermal decomposition of silicon halide, to a wettable powder composition containing O,O-dimethyl-N-methylcarbamoylmethyl dithiophosphate (dimethoate). The amount of the anhydrous silicon oxide depends upon the content of the active component such as dimethoate, and is preferably 10-30% when the wettable powder contains 40% dimethoate.
