Abstract
The invention belongs to the technical field of pesticide compounding, and particularly relates to theta-cypermethrin and ethofenprox containing water dispersible granules and an application thereof. The effective components of the theta-cypermethrin and ethofenprox containing water dispersible granules are theta-cypermethrin and ethofenprox, wherein the weight ratio of the theta-cypermethrin to the ethofenprox is 1:1-1:10. The theta-cypermethrin and ethofenprox containing water dispersible granules can be used for relieving the present pest resistance to insecticide to the greatest degree, thus the dosage of pesticide is reduced, and the influence on environments is also mitigated. The theta-cypermethrin and ethofenprox containing water dispersible granules are in line with the green and environmental protection trend of future society and has the optimal crop protection effect.
