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 
drying with a dryer, and screening granules with a 8-mesh screen and a 40-mesh screen with a screening 
machine to obtain the water dispersible granule formulated by trifloxystrobin and 
azoxystrobin. The water dispersible granule provided by the invention has the advantages of 
broad spectrum antibiotic, strong 
efficacy, 
low toxicity, fast disintegrating and the like.
