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.
