Abstract

The invention belongs to the technical field of pesticides and discloses a mixed herbicide containing halosulfuron-methyl and propyzamide. The halosulfuron-methyl and the propyzamide are employed in the herbicide as main active components according to the mass ratio of 0.1-80:0.1-80. The mixed herbicide can be applied for weeding a crop field, is wide in herbicidal spectrum, is quick and high in effect, is low-toxicity, is low in residue and is safe and environment-friendly, is reduced in use amount and residue, is good in environmental compatibility, is safe for people and animals, and is an excellent chemical herbicide for corns.

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 benzamid. The herbicide composition can be applied to post-emergence weeding in corn 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, purslane, night...
