Compound weed killer

Abstract

The invention belongs to the technical field of pesticides, and discloses a compound weed killer. The compound weed killer is characterized by containing two kinds of active ingredients, including azimsulfuron and bentazone. The composition is efficient, low-toxicity and broad-spectrum, and is safe and free of phytotoxicity to crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a compound herbicide of rimsulfuron-methyl and bentazone. 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] Bentazone is a contact-type selective post-emergence herbicide, which is used to treat stems and leaves at the seedling stage, and works through leaf contact. When used in dry fields, it first p...

Problems solved by technology

Field experiments have shown that long-term use of a single herbicide is not only prone to resistance and phytotoxicity, but also has a greater impact on the soil environment
