Abstract

The invention provides a weeding composition containing glufosinate-ammonium and fluoroglycofen-ethyl, and a preparation method of the composition, and belongs to the technical field of pesticides. The dosage form of the composition is a micro-emulsion, the composition comprises glufosinate-ammonium, fluoroglycofen-ethyl, a cosolvent, a first surfactant and a second surfactant, the first surfactant is alkyl glycoside, and the second surfactant is polyoxyethylene phosphonate or polyoxyethylene phosphonate salt. The weeding composition prepared in the invention has the characteristics of fast weeding speed, good weeding effect, low production cost and environmental protection, and has an obvious better weeding effect than single doses of glufosinate-ammonium and fluoroglycofen-ethyl. The preparation method has the advantages of simplicity, convenience in operation, and high feasibility; and the above product has stable quality, still has good quality stability after being stored for a long term, has obvious market values, and is suitable for large-scale promotion application.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to herbicides, in particular to a herbicidal composition containing glufosinate-ammonium and acifluorfen and a preparation method thereof. Background technique [0002] Glufosinate-ammonium (glufosinate-ammonium), also known as glufosinate, is a non-conductive herbicide with high efficiency, low toxicity and environmental friendliness. It is a glutamine synthesis inhibitor. Its chemical structure is as follows Shown: [0003] [0004] As a non-selective broad-spectrum contact herbicide with partial systemic effect, it is mainly used in orchards, vineyards, non-cultivated land, potato fields, etc. to control annual and perennial dicotyledonous and gramineous weeds, such as sage Oatmeal, crabgrass, barnyardgrass, wild barley, ryegrass multiflora, foxtail, golden foxtail, wild wheat, wild corn, perennial grasses and sedges, such as: duck sprouts, awn grass, fescue, etc. .
