The yield, composition and fungicidal activity of essential oils obtained from fennel fruits cultivated in Poland (FEO-POL) and Egypt (FEO-EG) were compared. The influence of the duration of hydrodistillation using a Clevenger apparatus on the essential oil yield was studied. The composition of the fennel essential oils was determined by GC-MS method. Studies have shown that FEO-POL and FEO-EG are two distinct chemotypes, which differ in yield and composition. The fennel fruits cultivated in Poland contained 4.14% of essential oil with trans-anethole as a main component. The plant material from Egypt was characterised by low content of essential oil (1.32%) with a predominant share of estragole. The fungicidal activity was tested in vitro against ten species of pathogenic fungi. The best result for FEO-POL was achieved against Sclerotinia sclerotiorum, Rhizoctonia solani and Botrytis cinerea. Antifungal activity of FEO-EG against tested fungi was weak or none.
