Abstract
The invention pertains to a method for manufacture and use of a herbicidal formulation containing the free acid form of glyphosate and an acid. Specifically, phosphoric, citric, acetic, propionic, and phosphorous acid and their corresponding salts have been useful in this application. The acid based formulations offer lower glyphosate use rates than standard formulations.
