Pesticide combination

Abstract

The invention discloses a pesticide composition comprising an active component A and an active components B, the active component A is selected from fluacrypyrim, the active component B is selected from any one of the following compounds: tebufenpyrad, propargite, fenazaquin and halfenprox, and the weight ratio A of active component A to active component B is 1:70-70:1. The composition of the invention can control a plurality of injurious insects, and has an obvious synergy effect, and the insecticidal spectrum is expanded, the dosage of the pesticide can be reduced, pesticide residues on crops can be reduced, and environmental pollution can be reduced.
