Glyphosate is a plant growth regulator with significant effects on ripening and sugar-increasing, low toxicity and low residue. It can be used for growth regulation of crops such as sugarcane, sugar beet, sweet potato, fruit, soybean and cotton. In addition, glyphosate has a methylene phosphonic acid structure, which conforms to the structure of phosphonic acid corrosion inhibitors, and can also be used as a metal corrosion inhibitor Chemicalbook agent. Organic phosphonic acid corrosion inhibitors can chemically react with Ca2+, Fe2+, etc. in water or solution to form a layer of insoluble precipitates or complexes, and continuously deposit on the metal surface to form a dense protective film. The metal surface is separated from the corrosive environment, reducing the metal corrosion rate.
