In vitro antifungal activities of five plant essential oils against Botrytis cinerea causing gray mold of orange

Abstract

Five essential oils i.e. Clove (Syzygium aromaticum L.), Thyme (Thymus vulgaris L.), Lavender (Lavendula anguistifolia L.), lemongrass (Cymbopogon citratus) and peppermint (Mentha piperita L.) were evaluated against mycelial growth of Botrytis cinerea at 0.5%, 1% and 1.5% concentration under in vitro condition by using Poisoned Food Technique. Among the five essential oils Thyme oil showed maximum growth inhibition of Botrytis cinerea. The next best essential oil which inhibited the mycelial growth of pathogen was Clove oil.
