Thickening auxiliary agent applicable to glyphosate and dicamba composite aqueous solution

Abstract

The invention discloses a thickening auxiliary agent applicable to glyphosate and dicamba composite aqueous solution. The thickening auxiliary agent is mainly prepared from water-soluble surfactants such as dodecyl polyoxyethylene oxide amine, lauryl sodium glycinate, oleamide propyl betaine and alkyl glycoside according to a certain proportion. The auxiliary agent has excellent thickening effectson glyphosate and dicamba composite aqueous solution; in addition, the temperature-resistant and cold-resistant performance of the aqueous solution is good.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pesticide adjuvant, in particular to a thickening adjuvant of glyphosate and dicamba compound water preparation. Background technique [0002] Glyphosate is a large-tonnage herbicide widely used at present. Due to its unscientific use for a long time, the resistance of weeds has developed rapidly, especially the resistance of some broad-leaved weeds has developed extremely rapidly. In order to slow down the development of glyphosate-resistant weeds, increase the rate of glyphosate-killing herbicides and expand the herb-killing spectrum, pesticide manufacturers use glyphosate and dicamba in combination, and study the preparation of a mixed preparation of the two, in which water Agents are the most common. [0003] The ammonium salt, isopropylamine salt and dimethylamine salt of glyphosate and dicamba all have good water solubility, and can be formulated into high-content wat...

AI Technical Summary

Problems solved by technology

[0003] The ammonium salt, isopropylamine salt and dimethylamine salt of glyphosate and dicamba all have good water solubility, and can be formulated into high-content water preparations. However, when the two exist in the same aqueous solution at the same time, there will be Saponification reaction, even layered precipitation

At present, researchers mainly use high-concentration surfactant micellar solubilization to solve the stability of low-content glyphosate and dicamba mixed water formulations, but they have not solved the stability of high-content mixed water formulations, and have formulated Thickened mixed liquid product with certain adhesion
