ABSTRACT:
A method of manufacturing a solid, water-soluble herbicidal composition comprising a water-soluble salt of a herbicidal compound is disclosed. The herbicidal compound is a water-insoluble compound that includes a carboxylic acid functionality, such as a phenoxy-substituted carboxylic acid compound or a substituted benzoic acid compound, and is sufficiently pure to form a dry, solid herbicidal salt composition after interaction with a suitable neutralizing base, such as ammonia, an alkylamine, a dialkylamine, a trialkylamine, a hydroxyalkylamine, a dihydroxyalkylamine, an alkaline salt of an alkali metal or a combination thereof. The dry herbicidal salt composition includes at least about 90% by weight of the water-soluble herbicidal salt, and dissolves rapidly and essentially completely in water to form an aqueous herbicidal solution including up to about 75% by weight of the water-soluble herbicidal salt.
