Abstract

The invention belongs to the technical field of pesticide compounding, and particularly relates to a suspension emulsion of theta-cypermethrin and pyridaben and the application of the suspension emulsion. The active ingredients of the compound include theta-cypermethrin and pyridaben, and the weight ratio of theta-cypermethrin to pyridaben is 5-20 to 1. The suspension emulsion of theta-cypermethrin and pyridaben 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.
