Water dispersible granule formulated by trifloxystrobin and cymoxanil and preparation method thereof

The invention discloses a water dispersible granule formulated by trifloxystrobin and cymoxanil and a preparation method of the water dispersible granule. The water dispersible granule contains the following materials by mass: 20% to 60% of trifloxystrobin original drug, 10% to 50% of cymoxanil original drug, 3% to 4% of wetting agent, 6% to 7% of dispersant, 4% to 5% of disintegrant and 6% to 15% of diluent, and also contains about 2% of binder and 1% to 2% of antifoaming agent. The method comprises the following steps that: (1) taking the following raw material ingredients by weight: the trifloxystrobin original drug, the cymoxanil original drug, the wetting agent, the dispersant, the disintegrant and the diluent, and uniformly mixing the raw materials; (2) pulverizing the above mixed ingredients with a jet pulverizer to obtainmother powder with particle size of more than 400 meshes; (3) adding deionized water into the mother powder, thoroughly mixing with a stirrer, granulating with a granulator, then dryi
