In order to investigate the effects of antifungal essential oils on postharvest decay and some quality factors of strawberry fruit, experiments were conducted under in vitro and in vivo conditions. The antifungal activates of essential oils obtained from fennel, anis, peppermint and cinnamon at concentrations 0, 200, 400, 600 and 800 mL L71 were investigated against Botrytis cinerea with four replications. In vitro results showed that the growth of B. cinerea was completely inhibited by fennel, cinnamon and anis essential oils at relatively low concentrations (400– 800 mL L71). In vivo results showed that all the used essential oils at all applied concentrations caused an increase in the shelf life and inhibited of B. cinerea growth on strawberry fruits completely in comparison to the controls. The results of this study confirmed the antifungal effect of four essential oils in both in vitro and on fruit postharvest.
