Abstract:
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.
