Abstract
A process for efficiently producing a water-dispersible particulate agricultural-chemical composition having improved disintegrability/dispersibility in water, the composition having a particular size in the range of 50-1,000 μm. The process is characterized by comprising the following steps (a) to (e): (a) a step of kneading an agricultural-chemical active ingredient, a surfactant, and water; (b) a step of extruding the resultant mixture through a screen having pores 600-2,000 μm in diameter to form granules; (c) a step of drying the granules; (d) a step of rotating two toothed rolls with irregularities on the surface arranged in parallel to each other, and leading the dried granules to pass between the toothed rolls thereby pulverizing the granules; and (e) a step of sieving the pulverized granules.
