Controlled release compositions of matter are disclosed comprising complexes for treating a population of ore or more aquatic organisms in a column of water. The complexes comprise a 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. A process for treating a population of one or more. terrestrial organisms comprising delivering to a terrestrial environment, a composition of matter consisting essentially of a controlled delivery system for treating a population of one or more terrestrial organisms which is an admixture of at least one carrier component in an amount from about 50 % to about 99% by weight, said carrier component consisting essentially of silicas, cellulose fibers, metal oxides, clays, infusorial earth, slag, lava, paper, hydrophobic wood pin chips, waste wood, sawdust, vermiculite, cork, corn cobs, bagasse, seeds, seed hulls, carbon materials, starches, modified starches, carrageenan, algin, xanthates, agar, fluorinated polymeric materials, polyolefins or copolymers thereof, plaster, gypsum, cement, concrete, asphalt, fiber glass, glass, metals, metal alloys, fabrics, mineral aggregate, leather, natural fibers, synthetic fibers, liposomes, lipospheres, or food proteins and combinations thereof, said composition optionally containing a joint-function carrier/coating agent which is a polyvinyl alcohol, polyethylene oxide, hydroxypropyl methyl cellulose, cetyl alcohol or stearyl alcohol, or combinations thereof, and from about 0.0001% to about 50% by weight of a bioactive agent for treating a population of one or more terrestrial organisms, where said bioactive agents are insecticides, toxicants, monomolecular surface films, petroleum oils, insect growth regulators, plant growth regulators, animal growth regulators, microbial control agents, medicaments, 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 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, 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.
