[Objectives] To explore the antibacterial effects of essential oils from pomegranate on two kinds of postharvest pathogenic fungi, and to provide reference for the exploration of new plant-derived preservatives for pomegranate. [Methods] The inhibitory effects of 15 kinds of plant essential oils on 2 kinds of pomegranate postharvest pathogenic fungi were studied. [Results] Tea tree oil and eucalyptus oil have good inhibitory effects on the mycelium growth of Coniella granati and Botrytis cinerea, and the fumigation treatment of pomegranate can inhibit the rot of fruit during storage to a certain extent. [Conclusions] Tea tree oil and eucalyptus oil can effectively inhibit the mycelium growth of two kinds of pathogenic fungi, and can better control the rot of pomegranate during storage. It is necessary to further study the fresh-keeping effect and antibacterial mechanism of plant essential oils on pomegranate.
