Method of manufacturing a dry water-soluble herbicidal salt composition

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.

Controlled release of bioactive materials using alginate gel beads

Alginate gel beads containing bioactive materials dispersed therein are the product and the process of this invention. These beads can be made to either float or sink in aqueous environments, and are capable of providing the controlled release of their bioactive materials when applied to terrestrial or aqueous environments.
