Abstract

Compositions comprising Methylobacterium with anti-fungal activity, methods for controlling plant pathogenic fungi, and methods of making the compositions are provided.

First claim

What is claimed is:

1. A method of treating a plant or plant part to increase plant yield, wherein said method comprises spraying, coating, partially coating, immersing, and/or imbibing the plant or plant part with a composition comprising a fermentation product comprising a Methylobacterium strain selected from the group consisting of NLS0109 (NRRL B-67340) and a derivative of NLS0109, wherein the derivative of NLS0109 has a sequence of any one of SEQ ID NOS: 9-11.

2. The method of claim 1 wherein said Methylobacterium is at a concentration of at least 5×10 7 colony-forming units per gram or 5×10 7 colony-forming units per milliliter.

3. The method of claim 1 wherein said composition further comprises a carrier.

4. The method of claim 1 wherein said composition further comprises at least one of:
(i) an agriculturally acceptable excipient comprising 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
(ii) an agriculturally acceptable adjuvant comprising 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, hydroxyrnethylpropylcelluloses, 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.

5. The method of claim 4 wherein the composition comprises an agriculturally acceptable excipient 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.

6. The method of claim 1 the plant part coated with the Methylobacterium composition is selected from the group consisting of a leaf, a stem, a flower, a fruit, a coleoptile, a root, a tuber, and a seed.

7. The method of claim 1 wherein said plant is selected from the group consisting of corn, a Brassica sp., alfalfa, rice, rye, sorghum, millet, sunflower, safflower, soybean, tobacco, potato, peanuts, cotton, sweet potato, cassava, coffee, coconut, pineapple, citrus trees, cocoa, tea, banana, avocado, fig, guava, mango, olive, papaya, cashew, macadamia, almond, sugar beets, sugarcane, oats, barley, tomatoes, lettuce, green beans, lima beans, peas, cucurbits, ornamentals, and conifers.

8. The method of claim 1 wherein said plant is a cereal plant selected from the group consisting of rice, wheat, corn, barley, millet, sorghum, oat, and rye.

9. The method of claim 1 wherein said plant is a turfgrass plant selected from the group consisting of annual bluegrass, annual ryegrass, Canada bluegrass, fescue, bentgrass, wheatgrass, Kentucky bluegrass, orchard grass, ryegrass, redtop, Bermuda grass, St. Augustine grass, and zoysia grass.

10. The method of claim 1 wherein said composition further comprises a beneficial microorganism other than said Methylobacterium strain.

11. The method of claim 10 wherein said beneficial microorganism is selected from the group consisting of a Bacillus sp., a Pseudomonas sp., a Coniothyrium sp., a Pantoea sp., a Streptomyces sp., a Trichoderma sp., a Rhizobium sp. and a Bradyrhizobium sp.

12. The method of claim 1 wherein the composition further comprises a second Methylobacterium strain selected from the group consisting of NLS0017 (NRRL B-50931), NLS0020 (NRRL B-50930), and a Methylobacterium strain derived from or related to NLS0017 or NLS0020, wherein the Methylobacterium strain derived from or related to NLS0017 has a sequence of any one of SEQ ID NOS: 37-39, wherein the Methylobacterium strain derived from or related to NLS0020 has a sequence of any one of SEQ ID NOS: 21-24.

13. The method of claim 1 wherein said Methylobacterium strain is NLS0109 (NRRL B-67340).

14. The method of claim 12 wherein said second Methylobacterium strain is NLS0017 (NRRL B-50931) or NLS0020 (NRRL B-50930).

15. The method of claim 1 wherein said plant is a cucurbit plant selected from the group consisting of cucumber, cantaloupe, and musk melon.
