Water dispersible granules and preparation method thereof

The invention provides water dispersible granules and a preparation method thereof. The water dispersible granule comprises the following components in parts by weight: 5-15 parts of emamectin benzoate, 20-40 parts of thiacloprid, 10-30 parts of azoxystrobin, 13-25 parts of a dispersing agent, 2-4 parts of a wetting agent, 0.5-2 parts of an antioxidant, 5-10 parts of a disintegrating aid and 0-20parts of a filler. According to the water dispersible granule, the generation probability of drug resistance of crop pests is reduced, the insecticidal effect is enhanced, and the insecticidal cost isreduced. 本申请提供一种水分散粒剂及其制备方法。上述的水分散粒剂包括甲维盐5份～15份、噻虫啉20份～40份、嘧菌酯10份～30份、分散剂13份～25份、润湿剂2份～4份、抗氧化剂0.5份～2份、助崩剂5份～10份和填料0份～20份。上述的水分散粒剂，降低了农作物害虫抗药性的产生几率，增强了杀虫效果，且减少杀虫成本。
