Thickening auxiliary agent of glyphosate and 2, 4-dropping acid compound aqueous solution

Abstract

The invention discloses a thickening auxiliary agent suitable for a glyphosate and 2, 4-D acid compound aqueous solution, and the thickening auxiliary agent is mainly composed of 30%-40% of propylene glycol stearate, 20%-30% of sorbitan triisostearate, 10%-20% of dodecyl dimethyl betaine, 2%-10% of lauramide propyl amine oxide and water. The auxiliary agent is low in cost and good in temperature resistance, and can improve the adhesiveness of the glyphosate and 2, 4-D acid compound aqueous solution in use and improve the emulsifying property at the same time.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a thickening aid for a compound water preparation of glyphosate and 2,4-D acid. Background technique [0002] Glyphosate is a large-tonnage biocidal herbicide widely used at present. Due to its unscientific use for a long time, the resistance of weeds develops rapidly, especially for some broadleaf weeds. In order to slow down the development of glyphosate-resistant weeds, increase the speed of glyphosate weed killing and expand the weed killing spectrum, pesticide manufacturers generally use glyphosate in combination with other herbicides. [0003] 2,4-Dilotic acid (molecular formula C 8 H 9 C l2 NO 3 ), molecular weight 221.0, white solid, pure product melting point 141℃, very small solubility in water, easily soluble in alcohol and lye. It is usually used in the form of salt or ester, and its sodium salt is a white solid with a melting point of 215-216 °C a...

AI Technical Summary

Problems solved by technology

Both glyphosate and 2,4-D acid have good water solubility, and both can be formulated into high-content water preparations. However, the water preparations have poor adhesion when used, and a certain amount of wetting agent needs to be added to traditional water preparations. In order to improve its wettability, the medicinal solution is easy to adhere to the surface of the plant and improve the efficacy of the medicine. However, the precipitation of the complex is easy to occur after adding a wetting agent, the stability is poor, and long-term storage is easy to hydrolyze and fail.
