Biocontrol offers a promising alternative to synthetic fungicides for the control of a variety of pre- and post-harvest diseases of crops. Black rot, which is caused by the pathogenic fungus  Ceratocytis fimbriata , is the most destructive post-harvest disease of sweet potato, but little is currently known about potential biocontrol agents for this fungus. Here, we isolated several microorganisms from the tuberous roots and shoots of field-grown sweet potato plants, and analyzed their ribosomal RNA gene sequences. The microorganisms belonging to the genus  Pantoea  made up a major portion of the microbes residing within the sweet potato plants, and fluorescence microscopy showed these microbes colonized the intercellular spaces of the vascular tissue in the sweet potato stems. Four  P .  dispersa  strains strongly inhibited  C .  fimbriata  mycelium growth and spore germination, and altered the morphology of the fungal hyphae. The detection of dead  C .  fimbriata  cells using Evans blue staining suggested that these  P .  dispersa  strains have fungicidal rather than fungistatic activity. Furthermore,  P .  dispersa  strains significantly inhibited  C .  fimbriata  growth on the leaves and tuberous roots of a susceptible sweet potato cultivar (“Yulmi”). These findings suggest that  P .  dispersa  strains could inhibit black rot in sweet potato plants, highlighting their potential as biocontrol agents.
