Abstract
In vitro antifungal activity of the essential oils from Monarda citriodora and Melaleuca alternifolia was evaluated on 15 common post-harvest pathogens of a variety of crops. Both oils exhibited a high level of antifungal activity both by direct contact and in the vapor phase. Oil from Monarda citriodora was generally more active than that from Melaleuca alternifolia, particularly against more rapidly growing fungal species.
