Potential Utility of Bacillus amyloliquefaciens SFB-1 as a Biocontrol Agent for Sweetpotato Black Rot Caused by Ceratocystis fimbriata.

ABSTRACT: Background/Objectives: Sweetpotato black rot, caused by Ceratocystis fimbriata, is a severe fungal disease in sweetpotato production. Biological control strategies represent a promising, environmentally sustainable approach to managing this disease. This study investigates the biocontrol potential of Bacillus amyloliquefaciens SFB-1 against C. fimbriata. Methods: The antagonistic activities of strain SFB-1 on C. fimbriata were assessed through in vitro assays, including evaluations of mycelial inhibition, spore germination, and mycelial morphology. Pathogenicity assays on harvested sweetpotato roots assessed lesion diameter and depth. A transcriptomic analysis of C. fimbriata exposed to strain SFB-1 was performed to explore the underl
