AI Technical Summary

Technical Problem

The existing solvent system for glufosinate-ammonium·ethoxysulfuron microemulsion has problems such as high toxicity, poor stability, easy decomposition and high cost, making it difficult to prepare qualified products and affecting efficacy and the environment.

Method used

A nonanoic acid + cyclohexanone composite solvent system was adopted, combined with lauramide propyl dimethyl tertiary amine, alkyl glycoside, sorbitan monolaurate polyoxyethylene (20) ether composite surfactant, and the pH value was adjusted to be slightly acidic to improve the stability and efficacy of glufosinate-ethyl carboxyflufenoxam microemulsion.

Benefits of technology

It significantly improves the stability and efficacy of microemulsions, making them suitable for weed control on non-arable land. They effectively control a variety of weeds, especially glyphosate-resistant weeds, and reduce the environmental burden.

Abstract

The invention provides a glufosinate-ammonium and fluoroglycofen-ethyl microemulsion as well as a preparation method and application of the glufosinate-ammonium and fluoroglycofen-ethyl microemulsion. According to the microemulsion disclosed by the invention, the composite solvent of the nonanoic acid and the cyclohexanone is adopted and has good compatibility with the two effective components, so that the problem of preparation stability encountered when the microemulsion is prepared from glufosinate-ammonium is solved. The glufosinate-ammonium-fluoroglycofen-ethyl microemulsion disclosed by the invention can be used for weeding in uncultivated areas, can be used for effectively preventing and treating gramineous weeds, broadleaf weeds and cyperaceae weeds, and has an outstanding effect of preventing and treating weeds with resistance to glyphosate.
