Molecular identification and phylogenetic characterization of banana-associated fungal pathogens and GRAS salt-based management

Year: 2026

Type: article

Abstract: Banana (Musa spp.) is among the most widely cultivated and consumed fruits globally, playing a vital role in food security and agricultural economies. However, its marketability and storage life are severely constrained by postharvest anthracnose, and crown rot and also fungal diseases such as Curvularia leaf spot, which result in substantial yield and quality losses. Reliance on chemical fungicides has raised concerns regarding environmental safety, pathogen resistance, and chemical residues. To address these challenges, the present study evaluated the antifungal efficacy of four Generally Recognized As Safe (GRAS) salts- sodium benzoate, sodium carbonate, sodium bicarbonate, and potassium sorbate under in vitro conditions. Results revealed that potassium sorbate was most effective against anthracnose caused by Colletotrichum spp., significantly reducing fungal growth, while sodium benzoate exhibited strong activity against Curvularia leaf spot caused by Curvularia lunata. These findings highlight GRAS salts as safe, residue-free, and eco-friendly alternatives to synthetic fungicides for sustainable banana disease management. Their application offers promising potential to enhance fruit quality, extend shelf- life, and reduce postharvest losses, thereby contributing to sustainable disease management and improved value-chain efficiency in banana production.
