Antifungal activity of selected volatile essential oils against Penicillium sp

Phytopathogenic fungi have been responsible for considerable economic losses in vineyards, and therefore, more attention should be paid to the development and implementation of preventative treatment that is environmentally friendly. The aim of this study was to evaluate the antifungal activity of ten essential oils (EOs) (viz. Mill., L., var. , L., L., L., L., L., L. and L.). For the antifungal activity evaluation against , , , , , , , , and a disc diffusion method was used. The ten EOs exhibited different antifungal properties. Three tested EOs ( L., L. and L.) at concentrations of 0.75, 0.50, 0.25 and 0.125 µL/mL showed antifungal activity, inhibiting the mycelial growth. The L. EOs exhibited a lower level of inhibition. Overall, Mill., var. , L., L., L., L., L. and L. were effective as fungicidal agents but their efficiency varied between the strains of fungi. L. showed strong antifungal activity against all tested strains at both full strength and reduced concentrations. These EOs could be considered as potential sources of antifungal compounds for treating plant fungal diseases.
