Claims20
A composition comprising:
- (i) a fermentation product comprising a Methylobacterium strain that inhibits growth of a plant pathogenic fungus, wherein said fermentation product is essentially free of contaminating microorganisms, and wherein the Methylobacterium strain is NLS0109 (NRRL B-67340) or a derivative thereof having a sequence of any one of SEQ ID NOS:
- 9-11;
- and
- (ii) at least one of an agriculturally acceptable excipient and/or an agriculturally acceptable adjuvant,
- wherein the agriculturally acceptable excipient comprises at least one component selected from the group consisting of woodflours, clays, activated carbon, diatomaceous earth, fine-grain inorganic solids, calcium carbonate, calcium bentonite, kaolin, china clay, talc, perlite, mica, vermiculite, silicas, quartz powder, montmorillonite, and mixtures thereof, and
- wherein the agriculturally acceptable adjuvant comprises at least one component selected from the group consisting polyvinyl acetates, polyvinyl acetate copolymers, hydrolyzed polyvinyl acetates, polyvinylpyrrolidone-vinyl acetate copolymer, polyvinyl alcohols, polyvinyl alcohol copolymers, polyvinyl methyl ether, polyvinyl methyl ether-maleic anhydride copolymer, waxes, latex polymers, celluloses, ethylcelluloses, methylcelluloses, hydroxy methylcelluloses, hydroxypropylcellulose, hydroxymethylpropylcelluloses, polyvinyl pyrrolidones, alginates, dextrins, malto-dextrins, polysaccharides, fats, oils, proteins, karaya gum, jaguar gum, tragacanth gum, polysaccharide gums, mucilage, gum arabics, shellacs, vinylidene chloride polymers and copolymers, soybean-based protein polymers and copolymers, lignosulfonates, acrylic copolymers, starches, polyvinylacrylates, zeins, gelatin, carboxymethylcellulose, chitosan, polyethylene oxide, acrylamide polymers and copolymers, polyhydroxyethyl acrylate, methylacrylamide monomers, alginate, polychloroprene, and syrups or mixtures thereof.
A method for suppressing a disease caused by a plant pathogenic fungus that comprises applying a composition comprising Methylobacterium NLS0109 (NRRL B-67340) or a Methylobacterium strain derived therefrom or related thereto to a plant, a plant part, to soil where a plant is grown, or any combination thereof in an amount that provides for a decrease in adverse effects caused by growth of said plant pathogenic fungus in said plant, plant part, a plant obtained from said plant part, or a plant grown in said soil, relative to adverse effects of said plant pathogenic fungus in a control plant, plant part, or plant that had not received an application of said composition or been grown in soil treated with the composition, wherein said Methylobacterium strain derived from or related to NLS0109 has a sequence of any one of SEQ ID NOS:
- 9-11.
A plant, plant part or seed that is at least partially coated with a coating comprising a composition comprising (i) a fermentation product comprising Methylobacterium NLS0109 (NRRL B-67340) or a Methylobacterium strain derived therefrom or related thereto having a sequence of any one of SEQ ID NOS:
- 9-11, wherein said fermentation product is essentially free of contaminating microorganisms, and wherein said coating is not naturally occurring on said plant, plant part, or seed.
