Problems solved by technology

The third is that glufosinate-ammonium has excellent performance, but is expensive. At present, the price of glufosinate-ammonium technical is about 10 times the price of glyphosate, and its output cannot meet the market demand. Mixing the two can reduce the cost of medication
[0004] As far as the present is concerned, there have not been several research tasks on special additives for glyphosate and glufosinate-ammonium compound water preparations that meet the requirements of economical, environmental protection and high efficiency. Heavy but a long way

Abstract

The invention relates to a thickened type glyphosate and glufosinate compound aqueous auxiliary agent and a preparation technology thereof. The thickened type glyphosate and glufosinate compound aqueous auxiliary agent is prepared from erucic acid KO, cocamidopropyl betaine, tallow amine ethoxylated, indole-3-butyric acid potassium, dodecyl polyglucoside, polyhexamethylene guanidine, polyethyleneglycol and de-ionized water. By adopting the thickened type glyphosate and glufosinate compound aqueous auxiliary agent, a surfactant has a very good weeding effect and also has good insecticidal andsterilization effects; the thickening type glyphosate and glufosinate compound aqueous auxiliary agent has the advantages of environment friendliness, no caking, convenience for utilization; the technology is simple and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of pesticide preparation, in particular to a thickened glyphosate and glufosinate-ammonium compound water adjuvant and a preparation process thereof. Background technique [0002] Glyphosate, the pure product is a non-volatile white solid, insoluble in water and common organic solvents, mainly ammonium or sodium salt, and its salt is completely soluble in water. Glyphosate is a post-emergence systemic non-selective, high-efficiency, broad-spectrum herbicide that kills weeds. By dissolving the waxy layer on the leaf diameter surface of weeds, the drug effect quickly enters the plant conduction system to cause weeds to dry up and die. It has a broad-spectrum , low toxicity, no residue, systemic conduction and excellent killing properties, non-selective to plants, all green plants, including crops. Glufosinate-ammonium was developed in the 1980s. In addition to its herbicidal activity, it also has insecticidal and fungi...
