Deciphering the Bacillus amyloliquefaciens B9601-Y2 as a Potential Antagonist of Tobacco Leaf Mildew Pathogen During Flue-Curing.

ABSTRACT: Tobacco leaf mildew caused by Rhizopus oryzae (Mucorales, Zygomycota) is an important and devastating post-harvest disease during flue-cured tobacco period, and also is known to cause diseases of fruits and vegetables. In this study, assessment of several candidate biological control agents were first tested in vitro to determine their antifungal activities and potential strains were further applied to tobacco leaves to prevent pathogen colonization during the tobacco-curing process. In vitro screening of 36 bacteria and the isolates of one fungus were performed for their antifungal activities against R. oryzae using dual culture method. Potential five isolates viz. Bacillus amyloliquefaciens B9601-Y2 (Y2), B. amyloliquefaciens YN201728 (YN2
