Abstract

The invention belongs to the technical field of pesticides, and discloses a weeding composition. The weeding composition is characterized by comprising azimsulfuron and carfentrazone which are active components. The weeding composition has the advantages that the weeding composition is used for preventing and treating annual gramineous weed and broadleaf weed in paddy rice fields and is wide in weeding spectrum, long in lasting period and convenient to apply, and obvious synergistic effects can be realized.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a herbicidal composition of rimsulfuron-methyl and mefentrazone. 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] Carfentrazone-ethyl is a triazolinone herbicide developed by FMC Corporation of the United States. Mefentrazone is a protoporphyrin oxidase inhibitor that disrupts membranes by inhibiting...
