Abstract

The invention relates to a vegetable pest pesticide. The vegetable pest pesticide is characterized being prepared by mixing emamectin benzoate and metaflumizone which account for 10 to 90 percent of the total amount of the pesticide respectively. The mixture of the emamectin benzoate and the metaflumizone effectively postpones the production of drug resistance, improves pest killing effect and effectively improves the toxicity to diamond back moth.

Description

Technical field [0001] The invention relates to a vegetable pest insecticide, in particular to a vegetable pest insecticide. Background technique [0002] When using emamectin benzoate (abbreviated as Proclaim) and metaflumizone alone to control the vegetable pest Spodoptera litura, due to the irregular continuous use in the past, the Spodoptera litura The drug resistance of the drug increases extremely fast, and it is easy to produce drug resistance, so the dosage of the drug needs to be increased, and the use effect is relatively low. Summary of the invention [0003] The technical problem to be solved by the invention is to provide a vegetable pest insecticide which can increase the service life of the medicament, delay the generation of pest resistance, reduce the dosage of the pesticide and reduce the use cost. [0004] In order to solve the above technical problems, an insecticide for vegetable pests is invented, which is characterized in that it comprises a mixed composition...
