Abstract

Microbial strains, compositions, and methods of use thereof to enhance the growth and/or yield of a plant are provided. Also provided are materials and methods for presenting, inhibiting, or treating the development of plant pathogens or phytopathogenic diseases. The disclosure also provides non-naturally occurring plant and derivatives thereof such as plants artificially infected with a microbial strain of the invention.

Claims

1-5. -5. (canceled)

6. A composition comprising a microbial strain or culture of SGI-003-H11 strain, deposited as NRRL B-50483, and an agriculturally effective amount of a compound or composition selected from the group consisting of a fertilizer, an acaricide, a bactericide, a fungicide, an insecticide, a microbicide, a nematicide, and a pesticide.

7. A composition comprising a microbial strain or culture of SGI-003-H11 strain, deposited as NRRL B-50483 claim 6, and a carrier.

8. A composition according to claim 7, wherein said carrier is a plant seed.

9. A composition according to claim 7, wherein said composition is a seed coating formulation.

10. A composition according to claim 7, wherein said composition is prepared as a formulation selected from the group consisting of an emulsion, a colloid, a dust, a granule, a pellet, a powder, a spray, an emulsion, and a solution.

11. A plant seed having a coating comprising a composition according to claim 9.

12. A method for treating a plant seed, said method comprising a step of exposing or contacting said plant seed with a microbial strain or culture according to of claim 7.

13. A method for enhancing the growth and/or yield of a plant, said method comprising applying an effective amount of a microbial strain or culture according to claim 7 to the plant, or to the plant'"'"'s surroundings.

14. A method according to claim 13, wherein said microbial strain or culture is grown in a growth medium or soil of a host plant prior to or concurrent with host plant growth in said growth medium or soil.

15. A method according to claim 13, wherein said plant is a corn plant or a wheat plant.

16. A method according to claim 13, wherein said microbial strain or culture is established as an endophyte on said plant.

17. A method for preventing, inhibiting or treating the development of a plant pathogen, said method comprising growing a microbial strain or culture according to claim 7 in a growth medium or soil of a host plant prior to or concurrent with host plant growth in said growth medium or soil.

18. A method according to claim 17, wherein said plant pathogen is selected from the group consisting of Colletotrichum, Fusarium, Gibberella, Monographella, Penicillium, and Stagnospora organisms.

19. A method according to claim 17, wherein said plant pathogen is selected from the group consisting of Colletotrichum graminicola, Fusarium graminearum, Gibberella zeae, Monographella nivalis, Penicillium sp., or Stagnospora noduruin.

20. A method for preventing, inhibiting or treating the development of a pathogenic disease of a plant, said method comprising applying an effective amount of a microbial strain or culture according to claim 7 to the plant, or to the plant'"'"'s surroundings.

21. A method according to claim 20, wherein said microbial strain or culture is applied to soil, a seed, a root, a flower, a leaf, a portion of the plant, or the whole plant.

24. A method for preparing an agricultural composition, said method comprising inoculating a microbial strain or culture according to claim 7 into or onto a substratum and allowing said microbial strain or culture to grow at a temperature of 137°

C. until obtaining a number of cells or spores of at least 10²-10³ per milliliter or per gram.
