Weeding composition and application thereof

Abstract

The invention relates to a compound herbicide containing glufosinate-ammonium and high-efficiency haloxyfop-methyl. The herbicide comprises the following main active ingredients: A, B and C, wherein Ais glufosinate-ammonium, B is high-efficiency haloxyfop-methyl, C is any one of selected from a group consisting of fluoroglycofen ethyl, oxyfluorfen and sulfentrazone, and a weight ratio of A to B to C is 1-100: 1-60: 1-60. The herbicide of the invention is used for treating post-emergence stems and leaves and preventing and eliminating grassy weeds, sedge weeds and broadleaf weeds.

Description

Technical field: [0001] The invention belongs to the field of agricultural herbicides, and relates to a compound herbicide, which is used for post-emergence stem and leaf treatment to prevent and control gramineous weeds, sedge weeds and broad-leaved weeds. technical background: [0002] Long-term use of herbicides with a single active component to control weeds will increase the resistance of weeds, reduce the sensitivity of weeds, increase the amount of application, and cause environmental pollution. Therefore, reasonable mixing of herbicides to improve herbicidal effect has become a current choice. Reasonable mixing of herbicides can not only expand the weeding spectrum and delay the emergence of weed resistance, but also improve the weeding effect and play a synergistic effect, significantly improving the effect of herbicides. According to previous search and research analysis, the inventor found that patent CN103688994A discloses the composition of glufosinate-ammonium...

AI Technical Summary

Problems solved by technology

The above-mentioned patents can delay the resistance of weeds to a certain extent, but they cannot play the role of "one drug with multiple weeds" in the weed control spectrum

CN105230653A discloses the composition of glyphosate, fluorfen and high-efficiency haloxyfop, but due to the large amount of glyphosate used, weeds are more resistant to it, so it is not suitable for a large amount of use
