Abstract

The invention discloses a weeding composition containing flucarbazone-sodium and halosulfuron-methyl. The weeding composition is composed of an active component, an auxiliary and a carrier, wherein the active component is composed of flucarbazone-sodium and halosulfuron-methyl in a weight ratio of (1: 50) to (50: 1), and the weight of the active component is 1-90% of the total weight of the composition; the dosage forms of the composition comprise wettable powder, water dispersible granules, oil suspending agent, powder, granules, suspending agent, dry suspending agent, emulsified oil, emulsion in water, micro-emulsion or suspending emulsion. The weeding composition disclosed by the invention has a synergistic effect, as well as is wide in weed-controlling spectrum, very safe to crops, and extremely low in influence on environment.

Description

technical field [0001] The invention relates to a herbicide, in particular to a herbicidal composition containing fluazosulfuron-methyl and chlorpyrazosulfuron-methyl. Background technique [0002] The chemical name of flucarbasulfuron-methyl (also known as flucarbazone-methyl, CAS No. 181274-17-9) is: N-(2-trifluoromethoxyphenylsulfonyl)-4,5-dihydro-3 -Methoxy-4-methyl-5-oxo-1H-1,2,4-triazolecarboxamide sodium salt. The structural formula is as follows: [0003] [0004] It is a novel sulfonylurea herbicide and an acetolactate synthase (ALS) inhibitor. Effective against grassy weeds and some important broad-leaved weeds, especially wild oats and foxtails that are resistant to ACC enzyme inhibitors, carbamates, dinitroanilines, etc. Its dosage is very low, very safe to crops such as wheat, and has a long lasting effect. [0005] The chemical name of clopyrazosulfuron-methyl (CAS accession number 100784-20-1) is: 3-chloro-5-(4,6-dimethoxypyrimidin-2-ylaminocarbonylamin...
