Pesticidal and acaricidal composition containing sufluoxime and tebufenpyrad

Abstract

The invention relates to a pesticidal and acaricidal composition containing sufluoxime and tebufenpyrad. The active ingredients of the composition are sufluoxime and tebufenpyrad in the weight ratio of (0.1-75):(80-1), preferentially (0.1-40):(50-5). The total mass content of the two active ingredients in the preparation is 1 to 90 percent, preferentially 5 to 60 percent. After being mixed with corresponding auxiliary agent and filler, the pesticidal and acaricidal composition can be prepared into a water emulsion, a microemulsion, missible oil, a suspending agent, wettable powder and water dispersible granules. The pesticidal and acaricidal composition is used for controlling various mites, such as red spider mites, yellow spider mites, rust mites, yellow tea mites, tetranychus cinnabarinus, tetranychus urticae and the like, and various insects with sucking mouth parts, such as aphides, thrips, psylla, mealybug, aleyrodid, scale insects and the like, of various fruit trees, such as orange trees, apple trees, grape trees, tropical fruit trees, pear trees and the like, various tea trees, and various crops and vegetables, such as cotton, soybean, humulon, potato and the like.

Description

Technical field: [0001] The invention relates to the technical field of pesticide compounding, in particular to a high-efficiency, environment-friendly insecticidal and acaricidal composition compounded with thiofluoroxime ether and tebufenpyrad as effective components. technical background: [0002] Thiofluoroxime is a new non-ester pyrethroid insecticide with independent intellectual property rights independently designed and synthesized by Hunan Research Institute of Chemical Industry in Hunan Base of National Southern Pesticide Innovation Center in 2002. The research and development code is HNPC-thiofluoroxime Ether 2005, chemical name: 1-(3-fluoro-4-chlorophenyl)-2-methylthioethanone oxime-O-(2-methylbiphenyl-3-methyl)ether, its structural formula is : [0003] [0004] Thiofluoroxime ether can effectively control tea tree pests, tea caterpillars, tea leafhoppers, tea inchworms, citrus pests leafminer moths, vegetable pests, cabbage caterpillars, etc., with a wide i...

AI Technical Summary

Problems solved by technology

After a long-term research in the field of compounding by the R&D personnel of our company, it was found that the two-component compounding of the new pyrethroid insecticide thiofluoroxime and the new acaricide tebufenpyrad can produce a good synergistic effect. Not only is it highly effective against mites, but it is equally effective against other tea tree pests and vegetable pests, and has a good promotion prospect, and there is no relevant report on this compound and its application.
