A significant postharvest loss of Karutha Colomban mango takes place in every season due to postharvest stem-end rot (SER) disease. In this research, antifungal efficacy of different of essential oils of basil, clove, and cinnamon were evaluated against SER causing fungal pathogens by conducting in vitro liquid and disc volatilization bioassays. Major bioactive compounds of the selected oils were identified by gas chromatography-mass spectroscopy. Liquid and vapor forms of all test oils successfully controlled SER-associated fungi viz. L. theobromae, Pestalotiopsis sp., and Phomopsis sp. In general, cinnamon bark oil at liquid and vapor phases displayed a higher in vitro antifungal efficacy than other oils. Based on the results, liquid spray and fumigation treatment systems could be developed in vivo to control SER in mango.
