Inhibitory effect of some plant essential oils on growth of Aspergillus niger, Aspergillus oryzae, Mucor pusillus and Fusarium oxysporum

The antifungal effects of sage, rosemary, anise, quinoa and savory essential oils against mycelium growth of Aspergillus niger, Aspergillus oryza, Mucor pusillus and Fusarium oxysporum were determined in in vitro conditions. While the 10 μg/ml of savory essential oil showed inhibitory effect against tested fungi, anise oil was ineffective at the same concentration. The essential oils of savory and sage showed a great inhibitor effects against M. pusillus when compared with other essential oils. The 20 μg/ml level of savory oil had effective on Aspergillus niger, Aspergillus oryza, Mucor pusillus and Fusarium oxysporum. The essential oils of sage and rosemary were effective on A. oryza, A. niger and Fusarium oxysporum at ligh concentrations (10 and 20 μg/ml). The essential oil of quinoa showed an antifungal effect at both concentrations (10 and 20 μg/ml) on all tested fungi. All the tested essential oils showed inhibitory effect against all the selected fungi.
