Combination acarus-killing compound containing hexythiazox

Abstract

The invention is a re-prepared anti-mite compound containing SMT, which consists of effective components like SMT and propargite, etc., and can be made into dosage forms like micro-emulsion, EC and suspo-emulsion. The weight percentage between the effective components of SMT and propargite is that SMT: propargite is equal to (1 to 30) : (1 to 60); the effective components of SMT and propargite have obvious complementary and synergism action. If being used for controlling the mites on fruit trees, the control effect of the invention is obviously better than a single agent of SMT and propargite, and the invention has the advantages of quick effect, long effective period and low usage cost. The control effect is free from temperature and the invention has an extremely obvious popularizing value.

Description

technical field [0001] The invention relates to a high-efficiency pesticide acaricide composition, which uses a combination of hexythiazox and propargite as active components. Background technique [0002] Acarid pests, commonly known as red spiders, are one of the main pests of fruit trees, cotton, vegetables and other crops. They not only seriously affect the growth of fruit trees and crops, but also because of the many generations of mites, they reproduce quickly and grow alternately. Therefore, it is quite difficult to control, and because the physiological mechanism of mites is different from that of general farmland pests, general high-efficiency insecticides have almost no control effect on mites. In the past, there were few special acaricides used to prevent and control mites in my country. Generally, dicofol, dicofol, isocarbophos, tin triazolium and their mixtures with diesel oil were used, and the control effect was not ideal. At the end of the 20th century, fore...

AI Technical Summary

Problems solved by technology

At present, there are many kinds of insecticide compositions, but in terms of acaricides, the development direction of known acaricide compositions is mainly to reduce the production cost and unit price of acaricides, and diesel oil is often used or the price is cheap. The combination of dicofol and other acaricides, although these products can meet the needs of the current rural purchasing power, but the control effect on mites is not ideal. The compound composition with different types of high-efficiency acaricides as the main components has not yet appeared, and has not been reported in domestic and foreign literature
