Abstract

The invention provides a glyphosate isopropylamine salt water solution and a preparation method thereof. The glyphosate isopropylamine salt water solution comprises 30.3 percent of glyphosate, 11.5 to 13 percent of isopropamide, 8 to 12 percent of tallowamine polyoxyethylene ether, 3 to 6 percent of alkyl polyglucoside and the balance of deionized water. The formula cost is reduced greatly, and the medicine effect of the glyphosate isopropylamine salt water solution is the same as that of glyphosate isopropylamine salt water solution pesticide with an expensive aid.

Description

technical field [0001] The present invention relates to a kind of herbicide and its preparation method, more specifically, the present invention relates to a kind of glyphosate isopropylamine salt solution and its preparation method. It belongs to the field of herbicides. Background technique [0002] Glyphosate (glyphosate) is a herbicide developed by Monsanto Company of the United States, also known as: glyphosate, Roundup, glyphosate, and phosphonic acid. The pure product is a non-volatile white solid with a specific gravity of 0.5. It melts at about 230°C and decomposes. The solubility in water at 25°C is 1.2%, insoluble in common organic solvents, and its isopropylamine salt is completely soluble in water. Non-flammable, non-explosive, stable in normal temperature storage. It has a corrosive effect on medium carbon steel and galvanized iron sheet (tinplate). [0003] The herbicidal properties of glyphosate were discovered by D.D. Baird in the United States in 1971, ...
