Abstract

The invention discloses a composite herbicide containing s-metolachlor and chlorimuron-ethyl. The composite herbicide takes s-metolachlor and chlorimuron-ethyl as effective components and the mass ratio of s-metolachlor to the chlorimuron-ethyl is (1-50) to (0.1-20); and the content of s-metolachlor and chlorimuron-ethyl accounts for 10%-70% of the herbicide by mass percent. The composite herbicide has the low toxin, weak sensitization and low toxin to people and livestock; compared with a single agent, for the composite herbicide disclosed by the invention, the pesticide effect is improved, the hybridization resistance is delayed, the weeding spectrum is wide and the lasting period is long; and the composite herbicide has the reliable safety on soybean plants and crops.

Description

technical field [0001] The invention relates to a compound herbicide containing metolachlor and chlorimuron-methyl, belonging to the field of pesticide herbicides. Background technique [0002] S-metolachlor (s-metolachlor), also known as Jinduer, molecular formula C 15 h 22 ClNO 2 , chemical name 1) 2-chloro-6-ethyl-N-(2-methoxy-1-methylethyl) acetyl-o-aniline, 2) 2-[[[[(4,6- Dimethoxypyrimidine-2) methyl amino]carbonyl]sulfonyl]methyl]benzoate. [0003] Structural formula: [0004] [0005] S-metolachlor is a chlorinated amide herbicide. It is a protein synthase inhibitor developed by Syngenta in 1975. It is a selective pre-emergent herbicide, which mainly inhibits protein synthesis by hindering protein synthesis. cell growth. It is often used for weed control in corn, soybean, peanut, sugarcane, cotton and other crop fields. In recent years, it has been found that S-metolachlor can effectively control annual grass weeds and some Cyperaceae weeds in soybean field...
