Abstract

Abstract Seed, especially delinted cotton seed, is coated with a polymeric-pesticide film wherein the pesticide release is programed to protect the plant during germination and plant growth. A precoat is preferably used on surfaces having linters thereon. Halogenated vinyl resin emulsions have been effectively employed as the film former and pesticide carrier.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 78 words
A COATED SEED OF A PLANT HAVING AN ESSENTIALLY ESTABLISHED GROWTH RATE AND COMPRISING A POLYMERIC/SYSTEMIC-PESTICIDE FILM ENCAPSULATING THE SEED, THE FILM COMPRISING A POLYMER MATRIX THROUGHOUT WHICH THE PESTICIDE IS SUBSTANTIALLY UNIFORMLY DISTRIBUTED IN AN EFFECTIVE AMOUNT NO HIGHER THAN THAT PERMITTED BY U.S.D.A. REGULATION, THE POLYMER BEING A HALOGENATED VINY RESIN CAPABLE OF PERMITTING RELEASE OF SAID PESTICIDE AT A PREDETERMINED RATE CONFORMING TO THE GROWTH RATE OF THE PLANT AND THE SEED BEING COTTON SEED.
Claim 2
Dependent Claim 78 words
A COATED SEED OF A PLANT HAVING AN ESSENTIALLY ESTABLISHED GROWTH RATE AND COMPRISING A POLYMERIC/SYSTEMIC-PESTICIDE FILM ENCAPSULATING THE SEED, THE FILM COMPRISING A POLYMER MATRIX THROUGHOUT WHICH THE PESTICIDE IS SUBSTANTIALLY UNIFORMLY DISTRIBUTED IN AN EFFECTIVE AMOUNT NO HIGHER THAN THAT PERMITTED BY U.S.D.A. REGULATION, THE POLYMER BEING A HALOGENATED VINY RESIN CAPABLE OF PERMITTING RELEASE OF SAID PESTICIDE AT A PREDETERMINED RATE CONFORMING TO THE GROWTH RATE OF THE PLANT AND THE SEED BEING COTTON SEED.
Claim 3
Dependent Claim 46 words
A coated seed of claim 1 whereins aid polymer is vinyl chloride resin selected from the group consisting of homopolymer, copolymer, and terpolymer and the systemic pesticide is organophosphorus compound, said pesticide concentration being from about 2 to about 12 percent by weight of the film.
Claim 4
Dependent Claim 26 words
Coated seed according to claim 1 wherein the pesticide is O, O-diethyl S-(2-(ethylthio)ethyl)phosphorodithioate, or 1,4-dichloro 2,5-dimethOxybenzene, or a mixture of -N-((trichloromethyl)thio)-4-cyclohexane-1,2-dicarboximide with 2,2 bis (p-methoxyphenyl)-1,1,1 trichloroethane.
Claim 5
Dependent Claim 32 words
Coated seed according to claim 1 wherein said halogenated vinyl resin is selected from the group consisting of vinyl chloride-vinylidene copolymers, vinyl chloride-butadiene-styrene terpolymers, vinyl chloride-butadiene-acrylonitrile terpolymers, polyvinyl acrylates, and mixtures thereof.
Claim 6
Dependent Claim 69 words
A cotton seed comprising a first coating of natural or synthetic resin adhesively adhering cotton fibers to each other and to the seed, a second coating completely contacting said first coating, said second coating comprising a polymeric pesticide film wherein the pesticide is systemic pesticide uniformly incorporated in said film in an effective amount for release at a predetermined rate conforming to the growth rate of the cotton plant.
Claim 7
Dependent Claim 69 words
A cotton seed comprising a first coating of natural or synthetic resin adhesively adhering cotton fibers to each other and to the seed, a second coating completely contacting said first coating, said second coating comprising a polymeric pesticide film wherein the pesticide is systemic pesticide uniformly incorporated in said film in an effective amount for release at a predetermined rate conforming to the growth rate of the cotton plant.
Claim 8
Dependent Claim 103 words
A process for treating cotton seed, which is of a plant having a rate of growth which process comprises: A. providing a uniform admixture of a film-forming halogenated vinyl resin emulsion with an effective concentration of systemic pesticide, which satisfies U.S.D.A. regulations for the seed, as a seed coating formulation; B. coating said seed with the pesticide resin seed coating formulation; and C. drying the resulting coating to form on the seed a uniform polymeric film having said pesticide uniformly distributed there through, the film being constituted to release the pesticide at a rate which conforms to the growth rate of the plant.
Claim 9
Dependent Claim 103 words
A process for treating cotton seed, which is of a plant having a rate of growth which process comprises: A. providing a uniform admixture of a film-forming halogenated vinyl resin emulsion with an effective concentration of systemic pesticide, which satisfies U.S.D.A. regulations for the seed, as a seed coating formulation; B. coating said seed with the pesticide resin seed coating formulation; and C. drying the resulting coating to form on the seed a uniform polymeric film having said pesticide uniformly distributed there through, the film being constituted to release the pesticide at a rate which conforms to the growth rate of the plant.
Claim 10
Dependent Claim 25 words
A process according to claim 6 wherein the vinyl resin is a vinyl halide polymer selected from the group consisting of homopolymer, copolymer, and terpolymer.
Claim 11
Dependent Claim 13 words
A process according to claim 6 wherein the pesticide is an organophosphorus insecticide.
Claim 12
Dependent Claim 23 words
A process according to claim 8 wherein from about 2 percent to about 12 weight percent of pesticide is in said polymeric film.
Claim 13
Dependent Claim 13 words
A process according to claim 6 wherein said seed is delinted cotton seed.
Claim 14
Dependent Claim 26 words
A process according to claim 6 wherein the pesticide is O,O-diethyl S-(2-(ethylthio)ethyl)phosphorodithioate, or 1,4-dichloro 2,5-dimethoxybenzene, or a mixture of N-((trichloromethyl)thio)-4-cyclohexane-1,2-dicarboximide with 2, 2 bis(p-methoxyphenyl)-1, 1,1 trichloroethane.
Claim 15
Dependent Claim 32 words
A process according to claim 6 wherein said halogenated vinyl resin is selected from the group consisting of vinyl chloride-vinylidene copolymers, vinyl chloride-butadiene-styrene terpolymers, vinyl chloride-butadiene-acrylonitrile terpolymers, polyvinyl acrylates, and mixtures thereof.
