Compound herbicide

Abstract

The invention belongs to the technical field of pesticide and discloses compound herbicide. The compound herbicide is characterized by containing the two active ingredients of azimsulfuron and oxyfluorfen. The compound herbicide is remarkable in synergistic effect, high in fast-acting property, wide in weeding range and long in lasting period.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a compound herbicide of rimsulfuron-methyl and oxyfluorfen. Background technique [0002] The molecular formula of Azimsulfuron is C 13 h 16 N 10 o 5 S, like other sulfonylurea herbicides, is an inhibitor of acetolactate synthase (ALS), which is rapidly decomposed into metabolites without herbicidal activity in rice, while weeds are absorbed through roots and leaves. Conducted in the plant, the weeds stop growing, the leaves turn green, and then die. It can effectively control weeds such as barnyardgrass, northern water hair flower, special-shaped sedge, purple water amaranth, eye vegetable, flower rush, and Alisma alisma. The structural formula is as follows: [0003] [0004] The molecular formula of oxyfluorfen is C 15 h 11 CIF 3 NO 4 , chemical name: 2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-trifluoromethylbenzene, is a fluorine-containing phenyl ether herbicide ...
