1. A method for decreasing nematode infestation and/or promoting growth in a plant comprising the step of
applying to the plant and/or seeds thereof and/or substrate used for growing said plant an effective amount of a whole cell broth collected from Bacillus megaterium strain J142 (NRRL Accession No. B 50771) fermentation, wherein said Bacillus megaterium strain J142 (NRRL Accession No. B 50771) comprises a 16S rRNA sequence as set forth in SEQ ID NO. 7; and
optionally another substance, wherein said substance is a pesticide and/or plant growth promoting agent.
2. The method of claim 1 , wherein the bacterium is in the form of a supernatant, filtrate, or cell fraction collected from said fermentation.
3. The method of claim 1 , wherein the pesticide comprises one or more single-site or multi-site anti-fungal agents.
4. The method of claim 1 , wherein the plant growth promoting agent comprises one or more synthetic or organic fertilizers and/or plant growth promoting microorganisms.
