Characterization and Management of Post-harvest Fungal Diseases in Banana (Musa paradisiaca)

Abstract

Banana (Musa spp.) is a vital crop globally, contributing significantly to food security and income generation, particularly in tropical regions like India. However, post-harvest fungal diseases pose a considerable threat to banana production, affecting both fruit quality and marketability. The current study investigated the isolation, characterization, and management of post-harvest fungal diseases in banana (Musa paradisiaca). Infected banana fruits were collected from the Dharashiv fruit market (Maharashtra, India), and pathogenic fungi were isolated and identified. Fusarium napiforme, Talaromyces atroroseus, Cladosporium cladosporioides, Fusarium sp., and Fusarium equiseti were the primary pathogens identified. DNA extraction and sequencing were employed for accurate identification, and sequences were submitted to GenBank. The antifungal activity of essential oils and plant extracts was evaluated using the Poisoned Food Technique. Essential oils from Syzygium aromaticum, Mentha piperita, and Punica granatum showed significant inhibition (P<0.05) of fungal growth, with clove and peppermint oils achieving 100% inhibition at higher concentrations. Plant extracts of Ocimum sanctum, Eucalyptus globulus, Mentha piperita, Zingiber officinale, Curcuma longa, Azadirachta indica, Piper betel, and Cymbopogon citratus were also tested, revealing notable efficacy, particularly with neem and peppermint extracts. The study that the efficacy of essential oils was more compared to aqueous plant extracts. The results suggested sustainable strategies for managing post-harvest fungal diseases in bananas and explained the importance of conducting field trials to validate laboratory results.
