Abstract:	The present work studied the antifungal activity of the alcoholic extracts obtained from three native plant species: burdock (Arctium lappa), thyme (Thymus vulgaris) and rough cocklebur (Xanthium strumarium). The demonstration of the antifungal activity was realized using Aspergillus ochraceus and Acremonium chrysogenum isolates. The antifungal activity of the selected plant extracts was evaluated by radial growth measurement on potato dextrose agar amended with plant extracts of different concentrations. Fungi were completely inhibited in the variant using plant extracts of the following concentration: 0.3 g plant material / ml to 70o ethanol. When using concentration of 0.075 g plant material / ml to 70o ethanol, the development of fungi was significantly inhibited.
