Fusarium graminearum causesFusarium head blight (FHB), a devastating disease that leads to extensive yield and quality loss in wheat and barley production. Integrated pest management (IPM) is required to control this disease and biofungicides, such as tetramycin, could be a novel addition to IPM strategies. The current study investigatedin vitro tetramycin toxicity inFusarium graminearum and evaluated its effectiveness for the control ofFusarium head blight FHB. Tetramycin was shown to affect three key aspects ofFusarium pathogenicity: spore germination, mycelium growth and deoxynivalenol (DON) production. Thein vitro results indicated that tetramycin had strong inhibitory activity on the mycelial growth and spore germination. Field trials indicated that tetramycin treatment resulted in a significant reduction in both the FHB disease index and the level of DON accumulation. The reduced DON content in harvested grain was correlated with the amount ofTri5 mRNA determined by qRT-PCR. Synergistic effects between tetramycin and metconazole, in both thein vitro and field experiments were found. Tetramycin could provide an alternative option to control FHB.

Fusarium graminearum causesFusarium head blight (FHB), a devastating disease that leads to extensive yield and quality loss in wheat and barley production. Integrated pest management (IPM) is required to control this disease and biofungicides, such as tetramycin, could be a novel addition to IPM strategies. The current study investigatedin vitro tetramycin toxicity inFusarium graminearum and evaluated its effectiveness for the control ofFusarium head blight FHB. Tetramycin was shown to affect three key aspects ofFusarium pathogenicity: spore germination, mycelium growth and deoxynivalenol (DON) production. Thein vitro results indicated that tetramycin had strong inhibitory activity on the mycelial growth and spore germination. Field trials indicated that tetramycin treatment resulted in a significant reduction in both the FHB disease index and the level of DON accumulation. The reduced DON content in harvested grain was correlated with the amount ofTri5 mRNA determined by qRT-PCR. Synergistic effects between tetramycin and metconazole, in both thein vitro and field experiments were found. Tetramycin could provide an alternative option to control FHB.
