Herbicide composition containing glufosinate-ammonium, glyphosate and fenflumezone

Abstract

The invention discloses a herbicide composition containing glufosinate ammonium, glyphosate and carfentrazone-ethyl. The herbicide composition is characterized in that the pesticide active ingredients of the composition are glufosinate ammonium, glyphosate or salts thereof and carfentrazone-ethyl; based on the herbicide composition, the weight percent of the pesticide active ingredients is 31.1-85%, wherein the weight percent of the glufosinate ammonium is 1-30%, the weight percent of the glyphosate or salts thereof is 30-70%, the weight percent of the carfentrazone-ethyl is 0.1-20%, and the balance is non-pesticide ingredients. The dosage forms of the herbicide composition are wettable powder, water dispersible granules, soluble powder, soluble granules, aqueous solutions, emulsion in water and microemulsion. The herbicide composition has the advantages that after compounding, the herbicide composition has obvious synergistic effects, expands the weed control spectrum, increases the weed control speed, obviously reduces the usage amount and numbers of use of herbicides and can be applied to controlling imperata cylindrica, ageratum conyzoides, dicranopteris dichotoma, eleusine indica, erigeron canadensis and other weeds in arable lands and non-arable lands.

Description

technical field [0001] The invention belongs to the technical field of agricultural herbicides, and in particular relates to a herbicide composition, especially a herbicide composition with glufosinate-ammonium, glyphosate or a salt thereof and fenclozone as active ingredients. The herbicide composition It can be used to control weeds such as Imperata cylindrica, Ageratum conyzoides, Dicranopteris dichotoma, Eleusine indica, Erigeron canadensis and other weeds. technical background [0002] Glufosinate-ammonium is also known as glufosinate, Baoshida, English common name glufosinate ammonium, CA registration number: 77182-82-2, chemical name; (RS)-2-amino-4-(hydroxymethoxyl)butyl ammonium acid. Molecular formula C 5 h 15 N 2 o 4 P, molecular weight 198.16. It is a phosphonic acid herbicide, a glutamine synthesis inhibitor, and a non-selective contact herbicide with partial systemic action. After application, the ammonium metabolism in the plant can be disturbed within ...

AI Technical Summary

Problems solved by technology

[0006] Imperata praecox, red thistle, iron mango, goosegrass, and small fly canopy are common weeds in various crop fields, forest land, and non-cultivated land. Using glufosinate-ammonium, glyphosate, or mefentrazone alone cannot effectively To control these weeds, the best control effect can only be increased

However, achieving the control effect by increasing the dosage will inevitably increase the herbicide residue, cause phytotoxicity to crops and increase the cost of control

Moreover, in practical application, the herbicide speed of using glyphosate alone is slow, and it is easily affected by bad weather such as low temperature and rainfall, which limits the efficacy of the drug.

In addition, long-term use of a single herbicide often leads to the emergence of weed resistance, thereby reducing the control effect of herbicides
