Abstract

The invention belongs to the technical field of pesticide, and discloses a mixed herbicide containing halosulfuron-methyl and amicarbazone; the mixed herbicide takes halosulfuron-methyl and amicarbazone as main effective components, and the mass ratio of halosulfuron-methyl to amicarbazone is (0.1-80) to (0.1-80). The mixed herbicide is applied in weeding of corn and sugarcane fields, has the advantages of wide weeding spectrum, quick acting, high efficiency, low toxicity, low residue, safety, environmental protection and the like, can reduce the dosage of pesticides, reduces residues of pesticides, has the advantages of being good in environmental compatibility, and safe to people and livestock and the like, and is a high-quality chemical herbicide for corn and sugarcane crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a mixed herbicide containing pyrazosulfuron-methyl and amfenclozone. The herbicide composition can be applied to pre-emergence weeding in corn and sugarcane fields. Background technique [0002] Clopyrazosulfuronmethyl (halosulfuronmethyl), molecular formula: C 13 h 15 ClN 6 o 7 S, chemical name: 3-(4,6-dimethoxypyrimidin-2-yl)-1-(1-methyl-3-chloro-4-methoxyformylpyrazol-5-yl)sulfonate Urea, also known as: pyrichlorsulfuron. Clopyrazosulfuron-methyl belongs to a new type of sulfonylurea herbicide, which is an inhibitor of acetolactate synthase. It is absorbed through the roots, stems and leaves of weeds, and is transmitted in plants. The weeds stop growing and then die. It is mainly used to control broad-leaved weeds and Cyperaceae weeds, such as velvetleaf, barn ears, datura, ragweed, amaranth, wild watermelon seedlings, Polygonum,...
