Abstract:
A process for treating a population of one or more aquatic organisms in a column of water consisting essentially of delivering to a preflood or flood area a composition of matter consisting essentially of a controlled delivery system for treating a population of one or more aquatic organisms in a column of water consisting essentially of an admixture of a carrier component, a bioactive agent for treating a population of one or more aquatic organisms, and at least one organic plasticizer coating component for regulating the controlled release rate and release profile of said bioactive agent in water, said carrier component being present in an amount of from about 50% to about 99% by weight and consisting essentially of silicas, cellulose fibers, metal oxides, clays, infusorial earth, slag, lava, paper, hydrophobic wood pin chips, vermiculite, cork, corn cobs, bagasse, seeds, seed hulls, carbon materials, starches, modified starches, carrageenan, algin, xanthate, agar, fluorinated polymeric materials, plaster, gypsum, cement, concrete, asphalt, wood, fiber glass, glass, metals, metal alloys, clothing fabrics, mineral aggregate, leather, natural fibers, synthetic fibers, liposomes, lipospheres, food proteins and combinations thereof, an optional joint-function carrier/coating which is a polyvinyl alcohol polymer, polyethylene oxide, hydroxpropyl methyl cellulose, cetyl alcohol, stearyl alcohol, and combinations thereof and from about 0.0001% to about 50% by weight of a bioactive agent for treating a population of one or more aquatic organisms, where said bioactive agents are insecticides, toxicant, monomolecular surface films, petroleum oils, insect growth regulators, plant growth regulators, animal growth regulators, microbial control agents, medicaments, antibiotics, pathogens, parasites, bactericide, viricides, fungicides, algaecides, herbicides, nematicides, amoebicides, miticides, acaricides, predicides, schistisoicides, molluscicides, larvicide, pupicides, ovicides, adulticides, nymphicides, attractants, repellents, growth stimulants, feeding stimulants, nutrients, hormones, chemosterilants, or pheromones, fragrances, flavorants, food additives and combinations thereof and from about 1.0% to about 50% by weight of at least one organic plasticizer coating component wherein said coating component is water soluble or biodegradable or erodible, for regulating the controlled release rate and release profile of said bioactive agent where said plasticizer is an acetate, adipate, azeleate, benzoate, caprylamide, capramide, caprate, citrate, cocotte, fumarate, glutarate, glycolate, heptanoate, isobutyrate, isophthalate, laurate, linoleate, maleate, mellitate, myristate, octanoate, oleate, palpitate, pelargonate, phosphate, phthalate, ricinoleate, sebacate, stearate, succinate, toluate, tallate, decanoate, or expoxidized vegetable oils, a toluamide, or chlorinated paraffins, said components being selected so that said complex will remain in an application site for a period of time sufficient to effectively treat a population of one or more of said organisms and wherein said composition is free of superabsorbent polymers.
