Abstract

The invention discloses an insecticide composition with chlorfenapyr and neonicotinoid insecticides, and a preparation and application of the insecticide composition. The insecticide composition comprises the chlorfenapyr and the neonicotinoid insecticides. The neonicotinoid insecticides are an optional type of imidacloprid, thiamethoxam, clothianidin, nitenpyram, thiacloprid, dinotefuran and acetamiprid. A mass ratio of the chlorfenapyr to the neonicotinoid insecticides is (0.05-20):1. An insecticide comprises the insecticide composition and auxiliary materials acceptable to the insecticide preparation with the insecticide composition. A mass percent content of the insecticide composition in the insecticide is 2%-6%. The insecticide composition, the preparation and the application have the advantages that obvious synergism effects can be realized for bradysia odoriphaga; the chlorfenapyr and the neonicotinoid insecticides have different action mechanisms, accordingly, the insecticide composition is beneficial to delaying development of pest resistance to the insecticide, and the service lives of the chlorfenapyr and the neonicotinoid insecticides can be prolonged; dosage of the neonicotinoid insecticides can be reduced, and accordingly neonicotinoid insecticide residual risks can be reduced; the preparation in various dosage forms is made of the insecticide composition, and accordingly excellent prevention and control effects can be realized for the bradysia odoriphaga.

Description

Technical field [0001] The invention relates to an insecticidal composition of tarfenil and neonicotinoid insecticides, preparations and applications thereof, and belongs to the technical field of pesticides. Background technique [0002] Chlorfenapyr, whose chemical name is 4-bromo-2-(4-chlorophenyl)-1-ethoxymethyl-5-trifluoromethylpyrrole-3-carbonitrile, is a In the late 1980s, an arylpyrrole insecticide and acaricide was successfully developed through the modification of the chemical structure of natural antibiotics. It is a blocker of mitochondrial oxidative phosphorylation in insects. [0003] Neonicotinoid insecticides are a class of highly effective insecticides. Their mechanism of action is to act on nicotinic acetylcholine receptors, interfere with the normal transmission of insects to the nervous system, and cause paralysis and death of insects. Common neonicotinoid insecticides include: imidacloprid, acetamiprid, nitenpyram, thiamethoxam, clothianidin, thiacloprid, dino...
