Interpretive Summary: Fusarium head blight is a major economical disease affecting wheat cultivation in the United States. A variety of strategies are employed to address this problem including externally applied chemicals and microorganisms. These promising additives combat Fusarium head blight by activating a induced systemic resistance in wheat. This study investigated the field application of promising chemicals and microorganisms on field grown wheat. The preliminary results show considerable more research is required to maintain externally additives on wheat heads and foliage in order to combat Fusarium head blight problem.

Technical Abstract: To determine whether some of the known biocontrol agents for Fusarium head blight (FHB) can activate induced systemic resistance (ISR) in wheat against FHB. To determine the potential of using ISR-inducing strains of plant growth promoting rhizobacteria (PGPR) to control FHB. To evaluate PGPR strains and autoclaved fungal biomass (AFB) preparations for effectiveness in controlling FHB in the field.
