Abstract

The invention relates to a pesticide of vegetable pest. The pesticide is characterized by comprising chlorfenapyr and chlorantraniliprole which account for 10 to 90 percent of the total amount respectively and are mixed. The compound agent of the chlorfenapyr and chlorantraniliprole effectively delays the generation of resistance, improves the pesticidal effect and effectively improves the toxicity to diamond back moths.

Description

technical field [0001] The invention relates to a vegetable pest insecticide, in particular to a vegetable pest insecticide. Background technique [0002] Chlorfenapyr (Chlorfenapyr) is a new type of heterocyclic insecticide, acaricide, and nematocide, and Chlorantraniliprole (Chlorantraniliprole) is an anthranilamide insecticide. The two have completely different mechanisms of action. And it has a good control effect on diamondback moth. [0003] In the past, when chlorfenapyr and chlorantraniliprole were used in large quantities to control the vegetable pest Plutella xylostella in the past, the resistance of the vegetable pest Plutella xylostella increased very fast, and it was easy to develop resistance. Therefore, it was necessary to increase the amount of pesticides used. The effect is relatively low. Contents of the invention [0004] The technical problem to be solved by the invention is to provide an insecticide for vegetable pests, which can improve the service ...
