Abstract
The invention discloses an azoxystrobin water dispersible granule and a preparation method thereof. The weight percentages of components of the azoxystrobin water dispersible granule are as follows: 10 percent to 80 percent of azoxystrobin, 2 percent to 12 percent of dispersant, 2 percent to 12 percent of wetting agent, 5 percent to 30 percent of disintegrating agent, 0.2 percent to 5 percent of defoaming agent, 0.2 percent to 5 percent of binder and the balance of carrier. The preparation method comprises the steps of evenly mixing all components of the azoxystrobin water dispersible granule, pulverizing the components into powder with a superfine jet mill, then granulizing, drying, screening, analyzing and testing to obtain the azoxystrobin water dispersible granule.
