In this study, the antibacterial effect of Origanum rotundifolium Boiss's essential oil was evaluated against 20 plant pathogenic bacteria. The essential oil (EO) of O. rotundifolium was hydrodistillated from wild O. rotundifolium plants that grown in Eastern Anatolia region of Turkey. Then, 10 chemical compounds of EO were identified via gas chromatography/mass spectrometry (GC-MS). The main compounds were determined as thymol (40.86 %-GC), carvacrol (43.62 %), p-cymene (5.95 %) and borneol (2.49 %). According to the results of the study, the essential oil of O. rotundifolium exhibits considerable antibacterial effect against pathogenic bacteria that cause significantly crop loss.
