A kind of water emulsion of high-efficiency trans-cypermethrin and fenoxycarb and its application

Abstract

The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to an emulsion in water of high-efficiency trans-cypermethrin and fenoxycarb and its application. The active ingredients of the composition are beta-cypermethrin and fenoxycarb, wherein the weight ratio of beta-cypermethrin and fenoxycarb is, beta-cypermethrin:fenoxycarb=1:1-1:5, the compound combination It effectively resists the problem of pest resistance, alleviates the current problem of pest resistance to the greatest extent, thereby reducing the amount of pesticides used, and also alleviates the impact on the environment. It is in line with the trend of green and environmental protection in the future society. The combination of the present invention Plants receive the best crop protection effect.
