Insecticidal and acaricidal composition containing SYP-9625 and bifenazate

Abstract

The invention relates to an insecticidal and acaricidal composition containing SYP-9625 and bifenazate. The insecticidal and acaricidal composition is characterized by taking SYP-9625 and bifenazate as active ingredients, the mass ratio of the two active ingredients is (0.1-50):(80-1), preferably (0.1-40):(50-10), and the total mass percentage content of the two active ingredients in the preparation is 5-90 percent, preferably 10-60 percent. After being added with corresponding aids and fillers, the insecticidal and acaricidal composition can be processed into an emulsion in water, a micro-emulsion, an emulsifiable concentrate, a suspending agent, wettable powder and water dispersible granules. The insecticidal and acaricidal composition is used for controlling mites such as red spiders, yellow spiders, rust louse, tea mites, tetranychus cinnabarinus and tetranychus urticae as well as piercing-sucking type mouthpart pests such as aphids, thrips, plant louse, mealinsects, whiteflies andscale insects on fruit trees and tea trees such as citrus trees, apple trees, grape trees, tropical fruit trees and pear trees as well as crops and vegetables such as cotton, soybeans, hops and potatoes.

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 ethifenapyr and bifenazate as active ingredients. technical background: [0002] Etofenazole belongs to pyrazole amides with high acaricidal activity. It has high activity against adults and nymphs, and even has a strong inhibitory effect on the hatching of mite eggs. At the same time, the synthesis method is simple and the cost of raw materials is low. [0003] The English common name of bifenazate is bifenazate, which is a new type of hydrazine ester compound. It is a specific acaricide, which is active during the active stage of spider mites, and can also prevent the egg stage of pests such as Tetranychus urticae. Laboratory studies have shown that it is non-toxic to predatory beneficial mites. Low toxicity to mammals, short residual period. [0004] As a new hydra...

AI Technical Summary

Problems solved by technology

At present, the pesticide preparations with bifenazate as the active ingredient are mainly 480g / L bifenazate suspension concentrate. During the use of the reagent, the quick effect is good, but if the two sides of the leaves and the surface of the fruit cannot be sprayed evenly, because there is no internal Absorptive, the killing of mites is not complete and the cost of use is high

The inventor found that the two-component combination of ethifenac and bifenazate can produce a good synergistic effect, and there is no relevant report on this combination and application
