Biological control of Fusarium moniliforme in maize.

Fusarium moniliforme is a facultative fungal endophyte and during the biotrophic endophytic association with maize, as well as during saprophytic growth, it produces fumonisins. The fungus is trainsmitted vertically and horizontally to the next generation of plants via clonal infection of seeds and plant debris. A biological control system using an endophytic bacterium, Bacillus sbutillis, has been developed that shows great promise for reducing mycotoxin accumulation during the endophytic (vertical transmission) growth phase. Because this bacterium occupies the identical ecological niche within the plant, it is considered an ecological homologue to F.moniliforme, and the inhibitory mechanism, regardless of the mode of action, operates on the competitive exclusion principle. In addition to this bacterium, an isolate of a species of the fungus Trichoderma shows promise in the postharvest control of the growth and toxin accumulation from F.moniliforme on corn in storage.
