Abstract

The invention belongs to the technical field of pesticide compounding and particularly relates to pyridaben-containing water dispersible granules and an application, wherein the weight ratio of tebufenozide to pyridaben is (15:1)-(1:5). Compared with a single dose, the pyridaben-containing water dispersible granules delay the generation of pesticide resistance of pests, enlarge the control spectrum of effective activity, improve the effect obviously to reduce the consumption of the pesticide, and reduce the degree of influence to the environment and the pesticide residue while reducing the pesticide use cost of farmers.

Description

Technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to a water dispersible granule containing pyridaben and its application. Background technique [0002] Pyridaben [0003] Pyridaben is a broad-spectrum, contact-killing acaricide, which can be used to control a variety of plant-eating harmful mites. It has a good effect on the entire growth period of the mites, namely eggs, juvenile mites, nymphs and adult mites. It also has obvious quick killing effect on the adult mites in the migration period. The drug is not affected by temperature changes and can achieve satisfactory results no matter if it is used in early spring or autumn.
