Problems solved by technology

[0003] With the extensive use of glufosinate-ammonium aqueous solution, the growth of glufosinate-resistant weeds cannot be inhibited. Therefore, glufosinate-ammonium compound products are produced, among which glufosinate-ammonium compound micro Emulsion is one of the most concerned products, but due to the strong water solubility of glufosinate-ammonium, it exists in the form of ions in aqueous solution. A large number of electrolyte ions will not only affect the stability of microemulsion, but also seriously restrict its auxiliary products. The selection and use of glufosinate-ammonium bicarboxyfen complex microemulsions on the market sometimes have quality problems such as delamination, crystallization and precipitation. Based on this, we propose a suitable for glufosinate-ammonium Emulsifier and application method of carboxyfluorfen microemulsion

Description

technical field [0001] The invention relates to the field of agricultural chemical surfactants, in particular to an emulsifier suitable for glufosinate-ammonium-haloxyfen microemulsion and an application method thereof. Background technique [0002] Glufosinate-ammonium is currently the second largest herbicide based only on glyphosate, and its main dosage form is 200g / l glufosinate-ammonium water solution. In recent years, due to the banning of paraquat aqueous solution in various parts of the world, the market of glufosinate-ammonium aqueous solution has developed rapidly. Especially in China, glufosinate-ammonium, as one of the substitutes for paraquat, has achieved unprecedented rapid development. [0003] With the extensive use of glufosinate-ammonium aqueous solution, the growth of glufosinate-resistant weeds cannot be inhibited. Therefore, glufosinate-ammonium compound products are produced, among which glufosinate-ammonium compound micro Emulsion is one of the most ...
