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.
