Controlled delivery compositions and processes for treating organisms in a column of water or land

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 a controlled delivery system for treating a population of one or more aquatic organisms, consisting essentially of an admixture of from about 50% to about 99% by weight of a carrier component, wherein said carrier component consists essentially of silica, 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, or food proteins 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, pharmaceuticals, medicaments, antibiotics, pathogens, biological control agents, parasites, bactericide, viricides, fungicides, algaecides, herbicides, nematicides, amoebicides, miticides, acaricides, predicides, schistisomicides, 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, glutamate, glycolate, heptanoate, isobutyrate, isophthalate, laurate, linoleate, maleate, mellitate, myristate, octanoate, oleate, palpitate, pelargonate, phosphate, phthalate, ricinoleate, sebacate, stearate, succinate, toluate, tallate, decanoate, or epoxidized vegetable oils, a toluamide or chlorinated paraffins, said components being selected so that said complex will permeate and remain in any planar or volumetric segment between the top and the bottom of a water column for a period of time sufficient to effectively treat a population of on or more of said organisms, and wherein said composition is free of superabsorbent polymers.
