Studies on the Formulation for Ammonium Salt of Glyphosate 75.7% Water Soluble Granule

The adjuvant of herbicide glyphosate with characteristics of good efficacy, mild quality, low cost and easy biodegradation was studied on tallow amine with a mean molar ethylene oxide(EO) content of 15, polyoxyalkylene alcohol sulfate AES, alkyl polyglucoside, tea saponin and ganosilicone. It was also applied into the formulation for ammonium salt of glyphosate 75.7% water soluble granule. The properties and effect of the product were tested and determined. It shows that the best formulation of the product is ammonium salt of glyphosate(95.5%) 79.3 g, tallow amine 10.4 g, polyoxyalkylene alcohol sulfate AES 2.6 g, ammonium sulphate 7.7 g. The product has high rate of dissolving, low surface tension and the decomposition rate of its active ingredient is less than 5% which conforms to the requirements of SG, further more, herbicidal activity against weed target excels domestic congeneric product and is equal to that of imports.
