Herbicidal compositions with reduced phytotoxicity

摘要

A method of reducing the crop plant phytotoxicity of sulfonamide or sulfonylurea herbicide formulations by reducing the pH of the formulation to below the pKa of said herbicide with an inorganic or organic acid and then adding a cationic surfactant to the formulation; in addition, the formulations and the agricultural uses of said formulations in water diluted form constitute a part of this invention.
