Controlled release compositions of matter are disclosed comprising complexes for treating a population of one or more aquatic organisms in a column of water. The complexes comprise at least one system wherein the system comprises at least one bioactive agent as a component selected for treating a population of aquatic organisms, at least one carrier component, and at least one coating component for regulating the controlled release rate and release profile of the bioactive agent in water or at least one bioactive agent and one joint-function component that can serve as both a carrier and coating to regulate the controlled release rate and release profile of the bioactive agent in water, with or without optional binder components and/or additional formulation materials. The components are selected to sink or float so that the complexes will permeate and/or remain in any planar or volumetric segment of a water column for a period of time that is sufficient to effectively treat a population of aquatic organisms. Methods for treating a column of water are also disclosed which comprises delivering the compositions to a column of water or to a dry preflood area (pretreatment) that will develop in a column of water or a flood area. The composition and process can also be used to treat terrestrial organisms.

1. An article of manufacture consisting essentially of a porous, degradable or soluble container having therein a composition of matter consisting essentially of a complex for treating a population of one or more aquatic organisms in a column of water, said complex consisting essentially of at least one controlled delivery system wherein said controlled delivery system consists essentially of an admixture of at least one carrier component, at least one bioactive agent as a component selected 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, said components being selected to sink or float so that said complex will permeate and remain in any planar or volumetric segment of a water column for a period of time sufficient to effectively treat a population of one or more aquatic organisms wherein said carrier consists essentially of from about 50% to about 99% by weight 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, xanthates, 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, or 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 where said bioactive agent is present in an amount from about 0.0001% to about 50% by weight and are insecticides, toxicants, monomolecular surface films, petroleum oils, insect growth regulators, plant growth regulators, animal growth regulators, microbial control agents, medicaments, antibiotics, pathogens, parasites, bactericides, viricides, fungicides, algaecides, herbicides, nematicides, amoebicides, miticides, acaricides, predicides, schistisomicides, molluscicides, larvicides, pupicides, ovicides, adulticides, nymphicides, attractants, repellents, growth stimulants, feeding stimulants, nutrients, hormones, chemosterilants, pheromones, fragrances, flavorants, food additives and combinations thereof, from about 1.0% to about 50% by weight of said organic plasticizer coating component wherein said organic plasticizer is water soluble or biodegradable or erodible, for regulating the controlled release rate and release profile of said bioactive agent where said plasticizer is acetate, adipate, azeleate, benzoate, caprylamide, capramide, caprate, citrate, cocoate, fumarate, glutarate, glycolate, heptanoate, isobutyrate, isophthalate, laurate, linoleate, maleate, mellitate, myristate, octanoate, oleate, palmitate, pelargonate, phosphate, phthalate, ricinoleate, sebacate, stearate, succinate, toluate, tallate, decanoate, or epoxidized vegetable oils, a toluamide or chlorinated paraffins, for regulating the controlled release rate and release profile of said bioactive agent, 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 terrestrial organisms, and wherein said composition is free of superabsorbent polymers.
