Problems solved by technology

[0003] In the prior art, there are already compositions containing glufosinate-ammonium and acifluorfen, for example, patents CN1169099A and CN1312683A disclose a synergistic herbicidal composition containing glufosinate-ammonium, including glufosinate-ammonium and acifluorfen, Patent CN102763676A discloses a composition containing glufosinate-ammonium and acifluorfen. In its patent document, it is recorded that glufosinate-ammonium and acifluorfen can be prepared into a microemulsion, but it is not described in the formulation implementation. In the case, the big reason may be

Embodiment 1

[0019] Glufosinate-ammonium 19%; Ethoxyfen 1%; Methyl oleate 10%; Polyethylene glycol 600 10%; Alcohol ether glycoside 6%, Alkylphenol formaldehyde resin polyoxyethylene ether 6%, Fatty alcohol poly Oxyethylene ether sulfosuccinic acid monoester disodium salt 3%; alkylphenol polyoxyethylene ether ammonium sulfate 2%; soft water to make up 100% vested.

[0020] The preparation method is as follows: according to the parts by weight, mix fluorfen, methyl oleate and polyethylene glycol 600, add alcohol ether glycoside, alkylphenol formaldehyde resin polyoxyethylene ether, fatty alcohol polyoxyethylene ether sulfonate Succinic acid monoester disodium salt, mixed slowly to obtain mixture A; glufosinate-ammonium, water and alkylphenol polyoxyethylene ether ammonium sulfate were mixed and stirred to obtain mixed solution B; slowly added B to A, Mix well and get it.

Embodiment 2

[0022] Glufosinate-ammonium 19%; Ethoxyfen 1%; Methyl Oleate 15%; Polyethylene Glycol 600 5%; Alcohol Ether Glycoside 5%, Alkylphenol Formaldehyde Resin Polyoxyethylene Ether 10%, Fatty Alcohol Oxyethylene ether sulfosuccinic acid monoester disodium salt 1%; alkylphenol polyoxyethylene ether ammonium sulfate 3%; soft water to make up 100% vested.

[0023] The preparation method is the same as in Example 1.

Abstract

The invention relates to a weeding composition and application thereof. The weeding composition is a microemulsion containing glufosinate-ammonium and fluoroglycofen ethyl and comprises 1 to 30% of glufosinate-ammonium, 1 to 10% of fluoroglycofen ethyl, 10 to 15% of a solvent, 5 to 10% of a cosolvent and 1 to 33% of a surfactant, with the balance being soft water. The microemulsion has the advantages of good stability, rational composition, good wetability and rain wash resistance, no pollution to environment, and no harm to people and livestock, and is suitable for promotion.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, and in particular relates to a microemulsion containing glufosinate-ammonium and acifluorfen. Background technique [0002] Microemulsion (microemulsion, ME) is a transparent single-phase liquid with water as the base, no or only a small amount of organic solvent, and an appropriate amount of surfactant and other additives. The microemulsion uses water as the main solvent, which not only saves a lot of organic solvents, but also greatly reduces the pressure on the environment after the application of the agent, which is of great significance for maintaining the agricultural ecological environment and is conducive to the sustainable development of agriculture. [0003] In the prior art, there are already compositions containing glufosinate-ammonium and acifluorfen, for example, patents CN1169099A and CN1312683A disclose synergistic herbicidal compositions containing glufosinate-ammonium, incl...
