Abstract
A protein-polysaccharide complex is used as a non-toxic and sustained release carrier for insecticides, herbicides, foliar nutrients and mixtures thereof. Methods for using a solution, solid or flowable impregnated protein-polysaccharide complex as a delivery agent for the control of plant populations and insect populations and as a preservative for cut flowers are described.

A controlled release plant protection agent delivery composition for controlling a population of plants or related vegetation in dry, moist, semi-aquatic, or aquatic environments comprising:
- (a) at least one protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein, and (b) at least one plant protection agent, said protein-polysaccharide complex and said plant protection agent being present in a total amount effective to control or fertilize a target population of vegetation or to control a target population of pests by ground or aerial application techniques. and wherein said composition is an admixture formed by mixing the protein-polysaccharide complex composition and the plant protection agent.
A herbicidal or pesticidal/herbicidal delivery composition for controlling a population of vegetation in dry, moist, semi-aquatic, or aquatic environments comprising:
- at least one protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein, and at least one formulation containing a herbicidal or pesticidal/herbicidal agent dissolved, suspended, or dispersed in an oil, surfactant, film-forming agent, or surface active agent and/or water, said polymer and agent being present in a total amount effective to control a population of vegetation and/or habitat-related pests, by ground and/or aerial application techniques, and wherein said composition is an admixture formed by mixing the protein-polysaccharide complex and the dissolved, suspended or dispersed formulation containing a herbicidal or herbicidal/pesticidal agent.
A method for controlling one or more population of plants without or in conjunction with other habitat-related pests comprising the steps of:
- preparing a herbicidal or herbicidal/pesticidal delivery composition comprising at least one protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein, and at least one formulation containing a herbicidal or herbicidal/pesticidal agent;
- and forming an admixture of said protein-polysaccharide complex composition and said formulation containing a herbicidal or herbicidal/pesticidal agent;
- and applying said herbicidal or herbicidal/pesticidal delivery composition in an amount effective to control the population of plants or habitat related pests to a dry, moist, semi-aquatic, or aquatic environment area needing plant control treatment or simultaneous plant and pest control treatment.
A controlled release pesticidal delivery composition for controlling a population of insects comprising:
- (a) at least one protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein, and (b) at least one formulation containing a pesticidal agent, said protein-polysaccharide complex and said pesticidal agent being present in a total amount effective to control a target population of pests by ground or aerial application techniques, and wherein said composition is an admixture formed by mixing the protein-polysaccharide complex composition and the formulation containing a pesticidal agent.
A foliar nutrient delivery composition for fertilizing a population of plants or related vegetation in dry, moist, semi-aquatic, or aquatic environments or preserving cut flowers comprising:
- (a) at least one protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein, and (b) at least one formulation containing a foliar nutrient, said foliar nutrient being present in a total amount effective to fertilize or preserve a target population of vegetation or flowers and wherein said composition is an admixture formed by mixing the protein-polysaccharide complex composition and the formulation containing a foliar nutrient.
A method of preserving cut flowers comprised of forming an aqueous solution containing (a) at least one protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein, and (b) at least one foliar nutrient, said foliar nutrient being present in a total amount effective to preserve a target population of cut flowers and inserting cut flowers therein.
