<p>This study evaluates the effectiveness of biocontrol agents <i>Trichoderma asperellum</i> INH-YS 004, and <i>Talaromyces annesophieae</i> INH-YS 006, in managing <i>Fusarium proliferatum</i>, a major pathogen causing banana fruit rot.

摘要

This study evaluates the effectiveness of biocontrol agents Trichoderma asperellum INH-YS 004, and Talaromyces annesophieae INH-YS 006, in managing Fusarium proliferatum, a major pathogen causing banana fruit rot. The impact of these treatments on mycelial growth, conidial germination, and fruit rot development was assessed. Results showed that T. asperellum INH-YS 004 exhibited significantly greater inhibition of mycelial growth (84%) than T. annesophieae INH-YS 006 (53%), while Mancozeb completely inhibited mycelial growth (100%). A similar trend was observed for conidial germination, where T. asperellum INH-YS 004 (80%) showed significantly higher inhibition than T. annesophieae INH-YS 006 (41%), whereas Mancozeb achieved complete inhibition (100%). In the co-inoculation assay, T. asperellum INH-YS 004 significantly reduced fruit rot development (74%) compared with T. annesophieae INH-YS 006 (37%), while Mancozeb completely suppressed disease development (100%). The untreated control group exhibited visible fungal growth and fruit rot lesions, confirming the pathogen’s activity. These results highlight the potential of T. asperellum INH-YS 004 as a potent biocontrol agent, with promising effects in reducing F. proliferatum growth and fruit rot. Although T. annesophieae INH-YS 006 showed moderate efficacy, further research is necessary to explore its antifungal mechanisms. The study supports the use of biocontrol agents in postharvest banana management and suggests further field trials to validate the findings.
