Abstract

The invention belongs to the technical field of pesticide compounding, and particularly relates to a water dispersible granule of theta-cypermethrin and pyriproxyfen and the application of the water dispersible granule. The active ingredients of the compound include theta-cypermethrin and pyriproxyfen, and the weight ratio of theta-cypermethrin to pyriproxyfen is 1 to 5-10. The water dispersible granule of theta-cypermethrin and pyriproxyfen maximally alleviates the problem of pest resistance to insecticide in the prior art, so as to reduce the pesticide consumption and the influence on the environment, and coincide with the trend for a green future society. The compound provided by the invention achieves the optimal crop protection effects.
