Compound weedicide for broad-leaved weeds

Abstract

The invention discloses a weedicide for broad-leaved weeds, which is characterized by comprising the following components: 20-40 wt% of pyroxsulam, 25-45 wt% of florasulam, 15-28 wt% of 2-methyl-4-chlorophenoxyacetic acid, 13-17 wt% of synergist, 1-2 wt% of assistant and 5-8 wt% of amide weedicide. The weeding rate of the weedicide adopting the component proportioning is up to 90%; and since multiple reagents are mixed, the weed can not easily generate drug resistance, thereby compromising long-term usage.

Description

technical field [0001] The invention relates to a compound herbicide for broadleaf grass, in particular to a herbicide for upland fields with high herbicide rate, and belongs to the field of agricultural herbicides. Background technique [0002] Most of the current herbicides use a single herbicide such as thiosulfone. If this single herbicide is used year after year, the weeds will have certain drug resistance, which will lead to the problem of poor weeding effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compound herbicide for broadleaf grasses, which has the characteristics of high weeding efficiency. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a compound herbicide for broadleaf grasses, characterized in that it comprises 20% to 40% by weight of acesulfame, 25% to 45% by weight florasulam, 15%~28% by weight of dimethyltetrachl...
