Special adjuvant of glyphosate potassium salt aqueous solution and salt aqueous solution using same

Abstract

The invention relates to a special adjuvant of glyphosate potassium salt aqueous solution. The special adjuvant comprises (by weight percentage) alkyl polyglycoside (APG) 10-80, fatty alcohol polyoxyethylene ether 0-20, betaine 0-40, tallow amine polyoxyethylene ether 0-20, and the balance of water. The contents of fatty alcohol polyoxyethylene ether, betaine and tallow amine polyoxyethylene ether are not simultaneously zero. The adjuvant adopts environment friendly surfactant such as APG and betaine, is safe, green and bio-degradable, and reduces environment pollution of pesticide. When the adjuvant is used for the glyphosate potassium salt aqueous solution, the adjuvant has good synergic effect to product. With the adoption of the adjuvant, the glyphosate potassium salt aqueous solution has the advantages of simple process, low cost, good hard water resistance, good compatibility with other pesticides, and no layering or condensation phenomenon.

Description

technical field [0001] The invention relates to a pesticide adjuvant, in particular to a special adjuvant for glyphosate potassium saline solution and a glyphosate potassium saline solution containing the adjuvant. Background technique [0002] Glyphosate is a low-toxicity, broad-spectrum and high-efficiency herbicide that kills herbicides. It is the largest herbicide sold and used in the world. Its structural formula is: [0003] O O [0004] ‖ ‖ [0005] HO—P—CH2—NH—CH2—C—OH [0006] ︱ [0007] Oh [0008] Glyphosate is an organic acid with low solubility in water. It can be reacted with alkalis to form soluble salts, such as organic amines, liquid ammonia, sodium hydroxide, potassium hydroxide, etc., which are widely used at present. The glyphosate dosage form is glyphosate isopropylamine saline solution, the content is mainly 41%, 62%. [0009] Since glyphosate is added as glyphosate isopropylamine saline solution, the production process is more complicated an...

AI Technical Summary

Problems solved by technology

[0009] Since glyphosate is added as glyphosate isopropylamine saline solution, the production process is more complicated and the cost is higher. In the past two years, glyphosate potassium salt solution formulations have been developed in China and have been popularized and applied. Glyphosate potassium saline solution mainly The active ingredient is a salt obtained by neutralizing glyphosate acid and potassium hydroxide. Since glyphosate potassium salt is different from glyphosate isopropylamine salt in physical properties, it is necessary to develop a new additive for grass Glyphosate potassium salt, currently there are few special additives available in the market for this system, and the hard water resistance of the commercially available special additives for this system is not good, and flocculation or sediment will occur when combined with hard water with high hardness , affecting efficacy
