Glyphosate is the most commonly used herbicide for farmers. It is also the largest variety of pesticides in production and sales. There are many kinds of glyphosate products on the market, including glyphosate ammonium salt, glyphosate isopropylamine salt and glyphosate potassium salt. Etc., the content is also different, making people dazzled and confused. Where are the differences between the different members of these glyphosate families? Which is more cost-effective? Uncover different levels of outerwear - 30% glyphosate is the real body At present, the common dosage forms of glyphosate are water and powder, and the proportion of water agent accounts for a large proportion. After the delisting of 10% glyphosate water, 33% glyphosate ammonium salt has a good cost performance, and more than 41% glyphosate isopropylamine salt has become the mainstream in the market. According to industry sources, glyphosate is poorly water-soluble, so it is convenient to use a salt with good solubility. It can be easily understood that 33% glyphosate ammonium salt is 30% glyphosate plus 3% ammonium, 41% isopropylamine salt is 30% glyphosate plus 11% isopropylamine, 37% potassium Salt is the same. The solubility of different salt types is different, but the content of glyphosate acid in the three aqueous active ingredients is 30%. Insiders pointed out that in addition to a few products, most of the glyphosate products on the market include 360 ​​grams per liter of glyphosate water, 480 grams per liter of glyphosate isopropylamine salt, according to its density, glyphosate content is also It is 30%. What is the difference in price? “Why does the price of glyphosate vary greatly? The content of active ingredients and raw materials are different, and the cost will vary greatly. The difference in additives is also very large. The cheaper additives are one to five thousand six thousand yuan, and the expensive ones are more than ten thousand yuan. The current testing standard only detects the content of glyphosate, but does not detect the content of isopropylamine salt. For the benefit of some manufacturers, they use the lower price ammonium salt to pretend to sell isopropylamine salt, falsify and deceive consumers. “Some glyphosate products are cheap because of the low content of active ingredients and poor production process. Simply using mother liquor to prepare a lot of salt and unreacted impurities, the side effects are large, which will cause problems such as soil compaction.†experts point out that there are some companies on the market directly as the original drug formulations to sell, glyphosate content is at least 95%, salt content of 98% can be done, so that farmers feel content high herbicidal effect will be better This is actually misleading. The herbicidal effect of glyphosate depends not only on how high the content is, but also on the addition of foliar adhesion and penetration. Avoid misunderstandings - not cheap and quick In view of the current market situation of glyphosate, industry insiders urged farmers to be rational when choosing glyphosate products, avoiding a few misunderstandings, and try to choose products with complete three certificates and standardized specifications. First of all, the higher the content, the better. Can not simply determine that 41% of the products are better than 33%, pay attention to the effective ingredients marked on the product label, especially the content of glyphosate acid, the general product will be the active ingredients glyphosate and glyphosate The salt content is marked. Some products with high content, such as the original drug, are difficult to add additives, but the effect is not good. Secondly, we cannot blindly pursue products with quick results. Glyphosate is a systemic herbicide. It is different from the contact-type pesticide. The system has a conduction process. Relatively speaking, the time is relatively slow. Generally, it takes effect in 5-7 days. The weed leaves turn yellow, half. Weeds will die slowly around the month, so products that claim to be effective should be extra careful. In addition, not the lower the price, the better. If the price is lower than the market price, there will be a situation where the content and the auxiliaries are insufficient. The herbicidal effect will be greatly reduced. If the figure is cheaper, it is necessary to buy more drugs to achieve the desired effect. It costs money and labor, and pollutes the environment. If the price is too high, consider whether you have added some hidden components and pay attention to the use of security issues.
