Application | compared with glyphosate sodium salt and potassium salt, glyphosate ammonium salt has the advantages of less caking, low manufacturing cost, advantages of high herbicidal activity. A glyphosate ammonium salt soluble granule (SG), developed by the U. S. Company, was mass produced in 1993. The dosage form was screened and finally selected as Mon 44068 adjuvant, which is characterized by greatly reduced toxicity to mammals and water and high herbicidal activity. The dosage form is a dust-free extruded granule with an average bulk density of 1.45/L, which is applied to a wide range of different temperatures and concentrations in control water conditions (soft or hard water). Can rapidly disintegrate into a solution, while it retains the ease of use of the liquid dosage form and the ease of handling (can be packaged in paper bags) on the packaging container. At the beginning of this century, the company's earliest commercial product in the Chinese market was the "747 agricultural and folk music" SG. It is a kind of soluble granules containing 74.7% glyphosate ammonium salt with 20% adjuvant and excipients, the appearance of light yellow or light yellow particles, particle size 1 ~ 3mm, into the water can be quickly dissolved in water, the solution was acidic. Due to the low toxicity, no solvent, no dust, so the farmers welcomed and favorite new products. The first glyphosate ammonium salt soluble granule "nongwang 757 SG" was developed in Xin'an group company in China, which contained 75.7% glyphosate ammonium salt. At present, the domestic development of glyphosate ammonium salt soluble granules and higher concentration of products, such as 80% and 88.8%, the main purpose is to reduce the cost and reduce the inventory. As far as the product quality of glyphosate ammonium salt soluble granules at home and abroad is concerned, there is still a certain gap between domestic products and foreign similar products, mainly in the quality and dosage of additives. |
Introduction | glyphosate salts are water soluble and therefore are processed as glyphosate soluble granules products. Glyphosate is a kind of fungicidal organic phosphine herbicide, which has the characteristics of a broad spectrum. It can not only control annual weeds, but also control perennial deep-rooted weeds. As an inactivated herbicide, it is mainly used in forestry, orchards, non-farmland and non-Farmland. According to the spirit of the relevant documents of the Ministry of Agriculture, the development of glyphosate preparation products should be shifted to high content, in the direction of pollution-free, the solubility of glyphosate acid in water is very low, so in the actual application process, the salt can be easily used and the use effect can be increased, and it is particularly necessary to develop a water-soluble dosage form with the same effect. |
