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 contacting the plant, one or more seeds of the plant,and/or soil in which the plant is grown, a composition comprising a bacterial strain of Chromobacterium subtsugae sp. nov. having NRRL Accession No. B-30655, in an amount effective to modulate said soybean cyst nematode infestation.

2. The method of claim 1, wherein the contacting comprises applying the composition to a seed of the plant prior to planting.

3. The method of claim 1, wherein the composition is added to the soil in furrow.

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

5. The method of claim 1, wherein the method promotes growth of the plant, compared to a plant that has not been contacted with the composition.

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

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

8. The method of claim 1, wherein the composition is a whole cell broth of Chromobacterium the subtsugae sp. nov.
