Insecticidal composition comprising sulfoxaflor and cyhalothrin

Abstract

The invention relates to an insecticidal composition comprising sulfoxaflor and cyhalothrin, wherein active ingredients are sulfoxaflor and cyhalothrin; the mass ratio of the sulfoxaflor to the cyhalothrin is 1-100:100-1; the better mass ratio is 1-24:24-1; the best mass ratio is 1-20:10-1; the active ingredients in the insecticidal composition account for 1-100% of the total mass percentage and 5-50% preferably; the remaining is auxiliary elements permitted to use and accepted in pesticides; and the insecticidal composition can be prepared to emulsifiable solution, emulsion in water, suspending agent and wettable powder preparation by a known method. The insecticidal composition which takes the sulfoxaflor and the cyhalothrin as main ingredients and is prepared by a certain ratio has obvious synergism on injurious insects, such as cotton bollworm, pink bollworm, cotton aphid, pyrausta nubilalis, phyllocnistis citrella stainton, scale insect nymphs, leaf mites, foliaceous moth larvae, budworm, aphid, plutella xylostella, mamestra brassicae, prodenia litura, helicoverpa assulta, oeobia undalis, cabbage caterpillar and the like of crops, such as fruit trees, vegetables, cottons, tobaccos and corns, etc; and the insecticidal composition has effect on sanitary insect pests, such as the mosquito, the fly and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing sulfoxaflor and cyhalothrin. Background technique [0002] Cyhalothrin, also known as cyhalothrin, is a pyrethroid imitation biopesticide with the characteristics of broad-spectrum insecticidal, high efficiency, fast speed and long-lasting effect. It has contact and stomach poisoning effects, broad insecticidal spectrum, strong knockdown power, and is very effective against Lepidoptera larvae. The residual effect period is very short, and the residual risk is very small. The general residual effect period of foliar spray is 2-3 days; but when the drug is applied to the soil, its persistent effect period is very long, up to 1-2 months. It also has a good effect on the larvae of various Lepidoptera pests that harm peanuts, wheat, rice, cotton, corn, fruit trees, vegetables, mulberry, tea and other crops, and has a certain killin...

AI Technical Summary

Problems solved by technology

From the perspective of the control effect on rice planthopper and wheat budworm, vegetable diamondback moth, cotton bollworm and beet armyworm, the ideal pesticide should have quick-acting and long-lasting performance. Currently, some pesticides used in production have long-lasting effect. Good, poor quick-acting, some have good quick-acting, poor lasting effect

The long-term effect and the quick effect cannot be taken into account, and the control effect is not ideal

The inventor found that compounding sulfoxaflor and cyhalothrin can produce a good synergistic effect, and the relevant reports about the compounding of sulfoxaflor and cyhalothrin have not yet been published
