Compositions and methods for modulating plant parasitic nematodes
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.
1. A method of 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, with a composition comprising a fermented whole cell broth collected from a strain of Burkholderia A396 (NRRL Accession No. B-50319), 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 the one or more seeds 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.
