Wheat mite control emulsion in water

Abstract

The present invention belongs to the technical field of compound pesticides, and particularly relates to a wheat mite control emulsion in water. The effective ingredients of the composition are theta-cypermethrin and triazophos, the weight ratio of triazophos to theta-cypermethrin is 5:1 to 1:5, the compound composition can effectively inhibit the problem of production of resistance of pests, and maximally alleviates the problem of the drug resistance of the pests in the prior art, thereby reducing the dosage of the pesticide, and alleviating the impact on the environment, and the compound composition is in line with the social trend of green and environmental protection, and the composition reaches the best effect of crop protection.
