Problems solved by technology

[0006] At present, there is no report on quizalofop-ammonium-ammonium and oxyfluorfen ternary compound suspension concentrate. The common glufosinate-ammonium and oxyfluorfen in the market are mainly microemulsion and oil suspension. This dosage form not only Requires a large amount of organic solvent or polar solvent, which is extremely polluting to the environment, and the production cost is high
However, the compounding of glufosinate-ammonium and quizalofop-ethyl has not been reported yet.

Abstract

The invention discloses a suspending agent auxiliary agent prepared by compounding glufosinate ammonium with quizalofop-p-ethyl and oxyfluorfen. The auxiliary agent is composed of the following components in percentage by mass: 1%-40% of styrylphenol polyoxyethylene ether phosphate, 1%-45% of a polycarboxylate dispersant, 1%-20% of lauramide propyl amine oxide, 1%-20% of dioctyl sodium sulfosuccinate and water. The auxiliary agent provided by the invention enables the dispersion and suspension performance of the pesticide composition to be stable, has an obvious synergistic effect, obviously delays the generation of weed resistance, reduces the number of times of repeated use of pesticides, and reduces the agricultural cost.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a high-efficiency adjuvant for a suspending agent of glufosinate-ammonium compound quizalofop-p-ethyl and oxyfluorfen. Background technique [0002] Glufosinate-ammonium is a phosphonic acid herbicide that can inhibit glutamine synthetase in the plant nitrogen metabolism pathway, thereby interfering with plant metabolism and causing plant death. Glufosinate-ammonium is an excellent non-selective, broad-spectrum contact herbicide. With the rise of glyphosate resistance and restrictions on the use of paraquat, the sales of glufosinate-ammonium continue to rise, and it has become the second largest genetically modified crop herbicide in the world. [0003] Oxyfluorfen belongs to fluorine-containing diphenyl ethers. It is a selective, pre-emergence and post-emergence herbicide with ultra-low dosage. The weeds are mainly killed by absorbing the agent through the coleopt...
