Abstract
Microbiological agents are provided for control of certain diseases of wheat and other cereals caused by Fusarium species, including Fusarium head blight of wheat and other cereals. These agents can also improve yield of wheat plants and cereals. The agents are novel isolates of Pantoea agglomerans and of Bacillus megaterium that exhibit the property of inhibiting fungal pathogens, particularly those produced by Fusarium species. Biocontrol compositions, and methods of using them to control plant pathogen development on wheat and cereal plants and for increasing plant yield, are also provided. The biocontrol compositions comprise a mixture of at least one microorganism selected from the group consisting of Pantoea agglomerans and Bacillus megaterium.
Claims21
A biocontrol composition comprising a mixture of a) at least one microorganism which is an antagonist against plant pathogens and b) a carrier for said at least one microorganism, wherein said at least one microorganism is Bacillus megaterium ATCC PTA 3461, and wherein said at least one microorganism is present in an amount effective for inhibiting plant pathogen development.
A process for inhibiting the development of a plant pathogenic disease caused by Fusarium species on a wheat plant or cereals, said process comprising applying to said wheat plant or cereals a composition containing a carrier and at least one microorganism which is an antagonist against plant pathogens and which Bacillus megaterium ATCC PTA 3461, in an amount effective to inhibit plant pathogen development on said wheat plant or cereals.
A process for increasing the yield of a wheat plant or other cereal, said process comprising applying to the plant or other cereal a composition containing a carrier and at least one microorganism Bacillus megaterium ATCC PTA 3461, in an amount effective to enhance the yield of said plant or cereal.
An isolete of Becillus megaterium ATCC PTA 3461.
