Abstract
The invention pertains to a method for manufacture and use of a herbicidal formulation of chlorinated carboxylic acid herbicides. A number of different solvents have been found useful in this application. Furthermore, the use of surfactants that act as solvents for the acid herbicides has been discovered. These formulations have shown superior herbicidal activity when compared to standard salt and ester forms.
