Black mold is an important storage disease of pomegranate caused by the fungus Aspergillus niger. The fungus A. niger is common as a saprophyte in soil and on decaying plant material. Survey of fungi associated with postharvest deterioration of pomegranate was conducted in three major markets in Allahabad district during January – February (2016). Rotten pomegranate obtained from the three selected markets viz. Mundera Mandi. Barana Mandi and Phulpur Manndi. Aspergillus niger was isolated from the infected pomegranate. Five essential oils viz. Syzgium aromaticum(Clove), Eucalyptus globus (Eucalyptus), Azadirachta indica (Neem),Citrus lemon(lemon),and Mentha piperita (Mint)were tested on A. niger in vitro condition. All the essential oils significantly inhibited the radial mycelia growth of the test pathogen (A. niger).The highest percentage growth inhibition was achieved with eucalyptus oil(100%) and clove oil (100%)essential oils against A. niger followed by Neem oil (22.66%), citrus(21.48), mint(17.4%). The present investigation showed that essential oils of the mention plants have antifungal effect on Pomegranate postharvest rot fungi.
