Abstract

Provided is a method for modulating soybean cyst nematode infestation of a plant comprising applying to the plant an effective amount of a composition comprising a Chromobacterium, Burkholderia, and/or Flavobacterium strain to modulate the soybean cyst nematode infestation. The composition may be applied directly to the seed or in a substrate for growing the plant, such as in the soil.

Claims

1. A method for modulating soybean cyst nematode infestation of a plant comprising the steps of:

contacting the plant, one or more seeds of the plant, and/or soil in which the plant is grown, with a composition comprising a fermented whole cell broth collected from

a bacterial strain of Flavobacterium sp. H492 (NRRL Accession No. B-50584), in an amount effective to modulate the soybean cyst nematode infestation.

2. The method of claim 1, wherein the contacting comprises applying the composition to one or more seeds of the plant prior to planting.

3. The method of claim 1, wherein the contacting comprises adding the composition to a soil in which the plant is grown.

5. The method of claim 3, wherein the composition is added to the soil by in furrow irrigation.

10. The method of claim 1, wherein the method reduces the number of soybean cyst nematodes in the soil, in the plant, or on the plant, compared to a plant that has not been contacted with the composition.

11. The method of claim 1, wherein the method promotes growth of the plant or the one or more seeds of the plant, compared to a plant that has not been contacted with the composition.

12. The method of claim 1, wherein the method increases the yield of one or moreseeds produced by the plant, compared to a plant that has not been contacted with the composition.

13. The method of claim 1, wherein the plant is a soybean plant.
