Abstract

The invention belongs to the technical field of pesticide compounding, and specifically relates to a water dispersible granule containing spirotetramat and applications thereof. The effective components of the composition are high-efficient trans-cypermethrin and spirotetramat, wherein the weight ratio of the high-efficient trans-cypermethrin to the spirotetramat is equal to 1:1 to 1:10. The water dispersible granule maximally relieves the problem of drug resistance of pests, thus reduces the using amount of pesticide and the pollution on environment, is accord with the trends of green and environment-friendliness in the future society, and achieves an optimum protective effect on crops.
