Technical Field

The invention belongs to the technical field of pesticides, and particularly discloses a cyantraniliprole-containing pesticide composition and application thereof.

Background

The cyantraniliprole is an anthranilamide pesticide developed by DuPont company, and can effectively activate the ryanodine receptor of insects, so that calcium ions in the cells of striated muscles and smooth muscles of the insects continuously open a release channel, and the calcium ions in cavities are rapidly reduced, so that pests are paralyzed and killed. The composite material has strong inhibitory insecticidal effect and good systemic property, and can be conducted in plants.

The Lambda-Cyhalothrin is mainly used for contact killing and stomach toxicity, and can achieve the effect of preventing and controlling pests by inhibiting insect nerve conduction, and is mainly used for preventing and controlling various pests such as aphids on crops such as cotton, cruciferous vegetables, fruit trees, tea trees and the like.

Neonicotinoid insecticides are a class of efficient, safe, highly selective insecticides that block normal conduction through the insect central nervous system, mainly by selectively controlling the insect nervous system nicotinic acetylcholinesterase receptors, thereby causing paralysis in the insect pests and death. The neonicotinoid insecticide can effectively control homoptera, hemiptera, coleoptera, lepidoptera and other pests, and is safe to mammals and environment. Can be used for stem and leaf treatment, and also can be used for soil and seed treatment.
