Insecticide containing tolfenpyrad and chlorfenapyr

Abstract

The invention discloses a pesticide containing tolfenpyrad and chlorfenapyr, and relates to the technical field of pesticide production. Only the tolfenpyrad and the chlorfenapyr which are low in toxicity and high in efficiency are adopted as the effective components of the insecticidal composition for use, so that the advantage of good prevention and control effect of tolfenpyrad on main insect pests of vegetables and the advantage of broad insecticidal spectrum after tolfenpyrad and chlorfenapyr are compounded for use are reserved; the defects that the use cost of tolfenpxrad is high and the control effect of chlorfenapyr is reduced year by year can be overcome, and the purpose of compounding synergism is achieved.

Description

technical field [0001] The invention relates to the technical field of pesticide production. Background technique [0002] Tolfenpyrad is a new type of pyrazole heterocyclic insecticide and acaricide. Its main mechanism of action is to prevent the oxidative phosphorylation of insects. . The drug has a wide insecticidal spectrum, and has a high control effect on various insects of the order Hemiptera, Hemiptera, Beetles, Hymenoptera, Diptera and mites. The worm peak was 48 hours after application. This variety has a completely different mechanism of action from the existing insecticides, and has multiple insecticidal effects, which complement and synergize with most existing insecticides. In particular, it has special effects against pests such as thrips, diamondback moths, scale insects, and green leafhoppers, and has high safety. At present, the cost of using a single dose of toxafenamide with high content is relatively high at present. [0003] Chlorfenapyr is a pyrrol...

AI Technical Summary

Problems solved by technology

The time limit for the single agent of chlorfenapyr to control the main insect pests of crops has been longer, the resistance of crop insect pests has been significantly enhanced, and the control effect has declined

[0004] Existing insecticides such as CN106342905A etc., but present insecticides have also adopted a large amount of other active ingredients except the above two active ingredients, so that the production process is complicated and each ingredient is incompatible with each other. The residual amount of soil is large and the residual time is long, which is not conducive to the formation of a good ecological environment
