AI Technical Summary

Technical Problem

Due to the long-term use of pyrethroids in existing sanitary insecticides, mosquitoes have developed resistance, there is a lack of rotation agents, and the existing knockdown agents and lethal agents are of a single type, making it difficult to effectively control pyrethroid-resistant mosquitoes and flies.

Method used

A compound composition of Es-bioallethrin and cycloheximidine or pyrimethrin is used as a knockdown agent and a lethal agent in a weight ratio of 1:20 to 2:1. It is prepared into suspension concentrate, wettable powder, emulsifiable concentrate and other dosage forms for quickly knocking down and killing mosquitoes and flies.

Benefits of technology

It has a significant synergistic effect, reduces the amount of insecticide used, delays the resistance of mosquitoes and flies, and provides low-toxic and high-efficiency insecticidal effects. It is suitable for preventing and controlling mosquitoes and flies, especially pyrethroid-resistant mosquitoes and flies, and reduces environmental load.

Abstract

The present application relates to the field of sanitary insecticide technology, and specifically to a sanitary insecticide composition and its application. The sanitary insecticide composition described in the present application comprises active ingredient A and active ingredient B, active ingredient A is Es-biothrin, and active ingredient B is selected from one of cycloheximide and pyrethroid. The mass ratio of active ingredient A and active ingredient B in the composition is 1:20 to 2:1, and the total weight of active ingredients A and B accounts for 1% to 40% of the composition. The sanitary insecticide composition described in the present application has excellent control effects on sensitive and resistant mosquitoes and flies, and is particularly beneficial for controlling pyrethroid-resistant mosquitoes and flies; and has significant synergistic effects, can reduce the amount of insecticide used, and delay resistance.
