Some farmers report that 95% glyphosate has a lower herbicidal effect than 41% glyphosate At a sales promotion meeting of herbicide products organized by a superior dealer, a village-level dealer who had just completed two years of agricultural management reported to the author that in order to build a brand and hit the market, he always purchases high-content grass. Glyphosate products, but users have reported that 95% of glyphosate has no 41% content of glyphosate. Why is this? He made a common mistake in most of the first-time agricultural sales peers, that is, high content. Products are good things, and low-level products are bad things. Cause Analysis Product registration marks are not all glyphosate content Glyphosate is the most abundant herbicide variety on the market. According to different auxiliary ingredients, it is divided into glyphosate ammonium salt, glyphosate isopropylamine salt, glyphosate potassium salt, etc.; according to the dosage form, there are water agents, soluble powders and soluble granules, and the contents thereof are also different. The true component of glyphosate is glyphosate rather than glyphosate. Since glyphosate acid itself is hardly soluble in water, it is made into various salts which are easily soluble in water for use, such as ammonium salts, isopropylamine salts, sodium salts, potassium salts, etc., and glyphosate ammonium salts. The three ammonium ions in the process have no herbicidal effect. When the pesticide product is registered, if it is registered according to the glyphosate name, it indicates the content of glyphosate; if it is registered with glyphosate ammonium salt, it indicates the content of glyphosate ammonium salt, which has no herbicidal activity. Ammonium ions are also counted as active ingredients. Therefore, under the same conditions, the herbicidal effect of glyphosate is much higher than that of glyphosate ammonium. For example, 33% glyphosate ammonium salt is 30% glyphosate + 3% ammonium, 41% isopropylamine salt is 30% glyphosate + 11% isopropylamine, and 37% potassium salt is also true . Although the solubility of the above three different salt types is different, the content of the three aqueous active ingredients glyphosate is 30%. This is why high levels of glyphosate herbicidal effects are not necessarily better than low glyphosate herbicidal effects. More glyphosate, please pay attention to China Pesticide Network
