Insecticide compound containing nitrile sulfluramid and cypermethrin

Abstract

The invention relates to an insecticide compound which belongs to the field of pesticide compound. In the invention, nitrile sulfluramid and cypermethrin are taken as the active ingredients of the insecticide compound. The mass ratio of the two active ingredients is (1-40):(40-1), preferably (5-24):(24-5), and optimally (10-15):(5-10). The total weight percent of the active ingredients in the insecticide compound is 1%-80%, and preferably 20%-50%. The rest is allowed and acceptable auxiliary ingredients in the pesticide. According to a known method, the insecticide compound can be prepared into missible oil, concentrate emulsion, micro-emulsion, water dispersible grain and suspending agent. After the nitrile sulfluramid and cypermethrin, as the active ingredients, are compounded into the insecticide compound at a certain ratio, the insecticide compound has an obviously enhanced effect of preventing and controlling sucking pests, such as plant hoppers, aphids, aleyrodids, leafhoppers, 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 cypermethrin. Background technique [0002] The rice planthopper is one of the main pests that harm rice production in southern my country and the middle and lower reaches of the Yangtze River. Among them, the brown rice planthopper and the white-backed planthopper are intermittent large-scale pests. Adults and nymphs gather at the base of rice plants to suck juice, causing Rice plants are yellow and dry, stems become soft or rotten and lodging. Brown rice lice are the most serious damage. According to statistics, the damage area in 2005 and 2006 was about 250 million mu. Generally, the loss of rice is 5-10%, and the rice yield is reduced by 10-20% in a major occurrence year, and some heavy fields lose 40-50%, or even no harvest. The main damage of SBPH is that adults and nymphs become poisonous bodies after suc...

AI Technical Summary

Problems solved by technology

From the perspective of the control effect on rice planthopper and wheat budworm, the ideal pesticide should have quick-acting and long-lasting performance. Poor effectiveness

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 cypermethrin can produce a good synergistic effect, and the relevant reports about the compounding of sulfoxaflor and cypermethrin have not yet been published
