What is glyphosate aqueous agent? Please introduce

What is glyphosate aqueous agent? Please introduce the glyphosate available in the market in many forms and dosage forms, such as glyphosate isopropylamine salt, glyphosate ammonium salt and glyphosate, among which 10% glyphosate aqueous agent and 41% glyphosate isopropylamine salt account for the vast majority. In accordance with the requirements of notice No. 1158 issued jointly by the Ministry of Agriculture and the Ministry of Industry and Information Technology, glyphosate water mixtures containing less than 30% glyphosate produced according to the original pesticide registration certificate and pesticide provisional registration certificate before August 31, 2012, can be sold and used during the product quality assurance period. In other words, the sale of glyphosate mixtures with less than 30% content will no longer be allowed after August 31 this year. So, what's the difference between 41% glyphosate isopropylamine salt and 30% glyphosate? glyphosate itself is insoluble in water, but its salt can be soluble in water, such as potassium salt, sodium salt, ammonium salt, isopropylamine salt and so on. The active ingredient of various glyphosate preparations is glyphosate, which is acidic and has poor water solubility. After the formation of salt, the water solubility increases, generally can form ammonium salt and isopropylamine salt, potassium salt, sodium salt and so on, the most common is ammonium salt and isopropylamine salt. First of all, in terms of weeding effect, potassium salt is slightly larger than isopropylamine salt, isopropylamine salt is slightly larger than ammonium salt and sodium salt. Glyphosate isopropylamine salt is the salt obtained by the neutralization reaction of glyphosate and organic base isopropylamine, which is more soluble in water, in which glyphosate is glyphosate. In the case of the same content, the herbicidal function of glyphosate was better than that of glyphosate isopropylamine salt, but their herbicidal spectrum and action mechanism were the same. In terms of content, for different salts of glyphosate, according to the national standards of pesticide name and glyphosate water agent, the content of effective components is calculated by the content of glyphosate, and the content of effective components is marked content * (0.95-1.10). The conversion coefficient between glyphosate isopropylamine salt and glyphosate is 1.349, that is, glyphosate isopropylamine salt is equal to 1.349 * glyphosate content. So we can calculate that 41% of isopropylamine salts and 33% of ammonium salts contain about 30% glyphosate. At present, 41% of isopropylamine salts on the market are prepared with raw drugs, while 30% of glyphosate on the market is not salty. Products registered under the name of glyphosate in the Ministry of Agriculture are marked with the content of glyphosate, while products registered under the name of glyphosate isopropylamine salt are marked with the content of glyphosate isopropylamine. But there is a difference between 41% glyphosate isopropylamine salt and 30% glyphosate: 41% glyphosate isopropylamine salt indicates that the product is glyphosate isopropylamine salt. While 30% glyphosate aqueous agent has the following possibilities: (1) 30% glyphosate aqueous agent exists in the form of isopropylamine salt, similar to 40.5% glyphosate isopropylamine salt (slightly lower) (2) 30% glyphosate aqueous agent exists in the form of potassium salt, similar to 37% glyphosate potassium salt (3) 30% glyphosate aqueous agent exists in the form of ammonium salt Similar to 33% glyphosate ammonium salt (4) both sodium salt and dimethylamine salt are possible.
