Abstract

The invention discloses a composition containing saflufenacil and a glufosinate-ammonium compound. The composition is prepared by blending a weeding composition and auxiliary components. The weeding composition is prepared from the following raw materials in parts by weight: 1 to 90 parts of saflufenacil and 1 to 40 parts of the glufosinate-ammonium compound. The composition is prepared from the weeding composition and the auxiliary components, and selection can be carried out according to pesticide dosage forms; saflufenacil and glufosinate-ammonium are compounded, so the prepared composition has a good weeding effect; the weeding composition is prepared by carrying out microencapsulation treatment on saflufenacil and the glufosinate-ammonium compound by using a microcapsule liquid raw material, so the usage amount of the composition is reduced compared with the usage amount of other herbicides; micro-capsule liquid contains a benzotriazole structure, so ultraviolet rays can be effectively absorbed; and through further cooperation between the micro-capsule liquid and a formed microcapsule, saflufenacil and the glufosinate-ammonium compound are effectively prevented from being decomposed under the influence of the ultraviolet rays, and the weeding effect of the composition is further ensured.

Description

technical field [0001] The invention relates to the technical field of herbicide preparation, in particular to a composition comprising saflufenacil and glufosinate-ammonium compounds. Background technique [0002] Glufosinate-ammonium is a broad-spectrum contact-killing herbicide with weak systemic effect. Unlike glyphosate for root-killing, glufosinate-ammonium kills leaves first, and can be transmitted in plant xylem through plant transpiration. Its quick-acting effect is lower than that of paraquat Between glyphosate and glyphosate, many weeds are sensitive to glufosinate, which can be used as a substitute for glyphosate in areas where glyphosate is resistant; [0003] Saflufenacil belongs to protoporphyrinogen oxidase (PPO) inhibitors, it can inhibit the activity of PPO in plants, damage the cell membrane, cause cell leakage, tissue necrosis, and eventually plant death, saflufenacil Amine is easily absorbed by roots, buds and leaves. Once absorbed, it is mainly transmi...
