Postharvest Application of Bacillus amyloliquefaciens PMB04 Fermentation Broth Reduces Anthracnose Occurrence in Mango Fruit

Anthracnose is a destructive postharvest disease of mango fruit, especially after ripening. The application antagonistic Bacillus spp. strains one many promising control strategies. B. amyloliquefaciens (PMB04) exhibits strong activity against anthracnose in strawberry yet has not been explored for fruit. Among seven tested rhizobacterial strains, PMB04 exhibited the strongest inhibition Colletotrichum gloeosporioides (Cg) growth. demonstrated better inhibitory Cg mycelial growth than fungicides pyraclostrobin and difenoconazole. A fermentation broth (PMB04FB) was prepared tested, showed superior efficacy reduction severity mangoes compared to suspension, difenoconazole, or pyraclostrobin. We further found PMB04FB increased mortality ratio conidia. Our study demonstrates that treatment with an effective method represents strategy processing.
