Antifungal activity of essential oils on mycelial growth of Fusarium oxysporum and Bortytis cinerea
In vitro study of the effect of different volumes of twelve essential oils on the mycelial growth of economically significant phytopathogenic fungi (Fusarium oxysporum and Botrytis cinerea) and it was compared to the effect of a fungicide. The antifungal activity of essential oils is decreased with the duration of incubation and it differs depending on the type of phytopathogenic fungus and the applied volume. The most effective antifungal effect on both tested fungi was in the essential oil of thyme, with lowest values of IC50 while the weakest effect was in essential oils of eucalyptus and lemon, with the highest values of IC50. Certain essential oils, when applied in certain volumes, had the same or even better effect on the inhibition of the growth of mycelium when compared to the tested fungicides.
