  • Solid glyphosphate-formulation and manufacturing process
    Patent number: 6475954
    Abstract: Disclosed is a solid formulation of the herbicidal active agent glyphosate [N-(phosphonomethyl)glycine] compressed into tablet form. It is applied in the agricultural and horticultural sectors to destroy unwanted vegetation. The solid formulation according to the invention consists essentially of free glyphosate acid, salifying agents (alkali or ammonium hydrogencarbonate or carbonate in conjunction with solid organic acids), biological activating agents and diluents. A suitably sized tablet can consequently be adapted to supply an appropriate dose of spray mixture per surface unit for small-scale users. Submerging in water causes the glyphosate to convert into a soluble salt. The resulting carbon dioxide facilitates rapid disintegration of the tablet.
