Abstract

The invention belongs to the technical field of pesticides and relates to a herbicidal composition containing flumetsulam and monosulfuron ester. The herbicidal composition contains the flumetsulam and the monosulfuron ester in a weight ratio of (50 to 1)-(1 to 10), wherein the total weight percentage of active components is 3-80% and the balance is auxiliary components which are permitted to use and can be accepted in pesticides. The flumetsulam and the monosulfuron ester compounded in a certain proportion have an obvious synergic effect and the herbicidal composition has a relatively good preventive effect when being applied to preventing and treating broadleaf weeds such as field horsetail (hippochaete ramosissmum), shepherd's purse, Erysimum cheiranthoides Linn., garden cress, flixweed, polygonum, procumbent speedwell, xanthium sibiricum, nightshade, amaranthus retroflexus, chenopodium album, piemarker (fruit), cleavers, and darura stramonium linn.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the compounding technology of pesticides, in particular to the compounding technology of flumesulam and monosulfuronate. Background technique [0002] flumesulam [0003] Chemical name: N-(2,6-difluorophenyl)-5-methyl-1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide; broad grass clear; 2' ,6'-Difluoro-5-methyl(1,2,4)-triazolo(1,5-a)pyrimidine-2-sulfonanilide [0004] Molecular formula of sulfafenacil: C12H9F2N5O2S [0005] Relative molecular weight: 325.294 [0006] Structural formula: [0007] [0008] The drug belongs to the triazolopyrimidine sulfonamide class, which is a typical acetolactate synthase inhibitor. By inhibiting the synthesis of branched-chain amino acids, protein synthesis is blocked and plants stop growing. Long residual effect period, broad herbicidal spectrum, suitable for soil, stem and leaf treatment. [0009] Monosulfurate [0010] Chemical name: ...
