Problems solved by technology

However, when imazethapyr and quizalofop-p-ethyl are used alone as a single agent, the herbicidal spectrum is narrow and the drug efficacy is not ideal, resulting in a decrease in the weed control effect year by year

Abstract

The invention discloses a mixed herbicide containing imazapic and quizalofop-p. The herbicide takes the imazapic and the quizalofop-p as main effective ingredients, wherein the mass ratio of the imazapic to the quizalofop-p is (0.1-80):(0.1-80). The mixed herbicide disclosed by the invention has the advantages of being broad in spectrum, quick in effect, high in efficiency, low in toxicity, safe, environment-friendly and the like in application to post-emergence weeding in a peanut field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and specifically relates to a binary compound containing imazethapyr and quizalofop-p-ethyl. The herbicide composition can be used for post-emergence weeding in peanut fields. Background technique [0002] Imazapic, chemical name: (RS)-2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)-5-methylnicotinic acid. The herbicide is an inhibitor of acetolactate synthase (ALS) or acetate hydroxyacid synthase (AHAS), that is, by inhibiting plant acetolactate synthase, preventing the biosynthesis of branched-chain amino acids, thereby destroying protein synthesis and interfering with DNA Synthesis and cell division and growth, eventually causing plant death. It has good control effect on monocot and dicotyledonous weeds, not only can kill the aboveground part of weeds well, but also has a strong control effect on the roots and underground stems of the weeds. It...
