Abstract

The invention discloses a weeding composition containing propoxycarbazone, pinoxaden and florasulam. The weeding composition comprises active ingredients, auxiliaries and a carrier, wherein the active ingredients include propoxycarbazone, pinoxaden and florasulam in a weight ratio of 1:(0.01-100):(0.01-100); the weight of the active ingredients is 1-90% of the total weight of the composition; the auxiliaries include wetting agent, dispersing agent, disintegrating agent, adhesive, emulsifying agent, thickening agent, defoaming agent and the like; the carrier is a solid or liquid carrier; and the form of the composition is wettable powder, water dispersible granules or oil suspending agent. The weeding composition disclosed by the invention has obvious synergy, wide weed-controlling spectrum, high activity, low toxicity and low cost.

Description

technical field [0001] The invention relates to a herbicide, in particular to a herbicidal composition containing propoxysulfuron, pinoxaden and florasulam. Background technique [0002] The chemical name of propabutsulfuron-methyl (CAS No. 181274-15-7) is: 2-[[(4,5-dihydro-4-methyl-5-oxo-3-propoxy-1H-1, 2,4-Triazol-1-yl)carbonyl]aminosulfonyl]benzoic acid methyl ester sodium salt. The structural formula is as follows: [0003] [0004] Propylenesulfuron-methyl is a novel sulfonylurea herbicide and acetolactate synthase (ALS) inhibitor. Not only is it safe for cereal crops and has no impact on subsequent crops, but it also has high environmental and ecological compatibility and safety. It can control grass weeds and some important broadleaf weeds. [0005] The chemical name of pinoxaden (CAS No. 243973-20-8) is: 8-(2,6-diethyl-4-methylphenyl)-1,2,4,5-tetrahydro-7 -Oxo-7H-pyrazolo[1,2-d][1,4,5]oxodiazepine-9-yl-2,2-dimethylpropanoic acid. The structural formula is as...
