Abstract FiveBetula species,B. pendula, B. browicziana, B. medwediewii, B. litwinowii, andB. recurvata, were collected from different parts of Turkey. The leaves of these species were hydrodistilled to yield the consequent essential oils. The essential oil compositions were investigated by GC/MS. 14-Hydroxy-β-caryophyllene was the main constituent in the oil ofB. pendula. 14-Hydroxy-4,5-dihydro-β-caryophyllene, a new compound, was identified as the main constituent in the oils ofB. browicziana, B. litwinowii, and B. recurvata. In the oil ofB. medwediewii methyl salicylate was the main compound. Various phytopathogenic fungi were studied by the agar tube dilution technique to test the antifungal activities of the essential oils at 400 μg/ml concentration. The essential oils showed strong antifungal activity againstCephalosporium aphidicola, Drechslera sorokinianse, Fusarium solani, andRhizoctonia cerealis.
