Abstract

The invention belongs to the technical field of pesticide, and discloses a mixed herbicide containing halosulfuron-methyl and flufenacet; the mixed herbicide takes halosulfuron-methyl and flufenacet as main effective components, and the mass ratio of halosulfuron-methyl to flufenacet is (0.1-80) to (0.1-80). The mixed herbicide containing halosulfuron-methyl and flufenacet is applied in weeding of wheat, corn and paddy rice fields, has the advantages of wide weeding spectrum, quick acting, low residue, low toxicity, safety, environmental protection and the like, and is a high-quality chemical herbicide for wheat, corn and paddy rice and other 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 flufenacet. The herbicide composition can be used for postemergence weeding in wheat, corn and paddy 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,...
