Azoxystrobin water dispersible granule

The invention relates to an azoxystrobin water dispersible granule. The granule comprises, by mass, 10-60% of azoxystrobin raw drug, 1-5% of an assistant (WP2850), 0.5-2% of an assistant (WP-2836), 0.5-2% of an assistant (SP2848), 0.1-0.5% of a solid antifoaming agent, 1-10% of diammonium hydrogen phosphate and 36-86% of ammonium sulfate. The granule is prepared through the following steps: mixing 10-60% of azoxystrobin raw drug, 1-5% of an assistant (WP2850), 0.5-2% of an assistant (WP-2836), 0.5-2% of an assistant (SP2848), 0.1-0.5% of a solid antifoaming agent, 1-10% of diammonium hydrogen phosphate and 36-86% of ammonium sulfate, milling through using a jet mill until fineness according with standard requirements, adding water, mixing, granulating, drying, and screening until standard requirements are met. A detection result shows that the quality control indexes of the granule are obviously improved, the dosage can be easily and effectively controlled under same spray volume conditions in the practical process, the normal performance of the drug effect is promoted, the dispersion of the granule to a suspension is fast, the foam generation amount is small, the blending frequency is reduced, and the blending time is shortened, so the working efficiency is improved.
