Summary |
Application of essential oils of medicinal plants is considered a safe and acceptable method for plant disease management to protect plants from pathogenic microorganisms. Thus, in recent study, essential oils (EOs) from Zhumeria majdae, Heracleum persicum (two Iranian endemic plants) and Eucalyptus sp. were assayed for their antifungal potential against ten phytopathogenic fungi, including Fusarium graminearum, Fusarium asiaticum, Fusarium redolens f.sp. dianthus, Fusarium verticillioides, Fusarium oxysporum f.sp. lentis, Sclerotinia sclerotiorum, Aspergillus flavus, Aspergillus tubingensis, Botrytis cinerea and Cladosporium cladosporioides. Chemical composition of these oils was identified by GC-MS analysis. Based on our results, Z. majdae essential oil exhibited the best antifungal activity among tested essential oils, completely inhibiting growth of five fungal species. EOs of Eucalyptus sp. and H. persicum showed moderate and poor antifungal capacity, respectively. GC-MS analysis demonstrated that linalool and camphor were the main components of the essential oils of Z. majdae; furthermore, 1,8-cineole and hexyl ester formed the major portions of Eucalyptus sp. and H. persicum EOs. Due to the significant inhibition of some EOs, additional research about their use for control of plant diseases caused by these fungi is recommended.
