Problems solved by technology

In actual production, conventional pesticides are used to control pest mites in large areas for a long time. Improper application of pesticides can not eradicate them in one application. Repeated pesticide application not only increases labor costs, causes serious pollution to the ecological environment, but also increases the resistance of pest mites.

Abstract

The invention belongs to the technical field of pesticides, and relates to an acaricidal composition containing a mitochondrial oxidative phosphorylation inhibitor. The active ingredients of the acaricidal composition include active ingredient A and active ingredient B; the active ingredient A is mitochondrial oxidized phosphoric acid Inhibitor compounds, the active ingredient B is a compound shown in formula (I). The pesticide composition or the preparation thereof of the present invention can efficiently kill mites, quickly prevent harmful mites from feeding, and reduce the population base of insects; the mechanism of action is unique, the control effect on various harmful mites is stable and reliable, and the spectrum of killing mites can be expanded.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to an acaricidal composition containing a mitochondrial oxidative phosphorylation inhibitor. The advantages of wide mite spectrum. Background technique [0002] Agricultural pest mites are small in size, reproduce quickly, have many generations, and have strong applicability. They are typical r-strategy fulminant pests and are recognized as one of the most difficult pest communities to control. Among them, spider mites and gall mites are the most harmful. They covertly gather and harm, suck plant juice, hinder plant growth, make leaves chlorotic, discolored or curled, shrunk, deformed, and can spread viral diseases. They are called vampires of plants. [0003] The compound of formula (I) was developed by Japan Combination Chemical Industry Co., Ltd., with the development code KII-9396. (RS)-[5-[4-Chloro-2-fluoro-5-[(2,2,2-trifluoroethyl)sulfinyl]phenoxy]pentyl]trifluorome...
