Abstract :In this study, the antibacterial effects of essential oils obtained from different Satureja species (Satureja cuneifolia Ten., Satureja spicigera (C. Koch) Boiss., Satureja thymbra L., Satureja hortensis L. and Satureja cilicica P.H. Davis) against Xanthomonas phaseoli pv. phaseoli (Smith) Vauterin and Xanthomonas citri subsp. fuscans (Burkholder) Starr & Burkholder, which cause common leaf blight in bean plant, were tested. Essential oils were found to significantly inhibit the growth of bacterial strains of both disease agents in vitro, and the lowest concentrations that prevent bacterial growth were determined for both pathogens. The effects of essential oil applications on seed germination, number of infected cotyledons and disease severity were also evaluated. It was determined that essential oils of S. cuneifolia and S. spicigera has no negative effects on seed germination while essential oils of S. hortensis, S. thymbra and S. cilicica caused a little decrease in seed germination compared to the control. As a result of S. cuneifolia + pathogen and S. spicigera + pathogen applications, no infected cotyledons were detected, and it was determined that the disease development caused by two pathogens was prevented by 100%.Keywords : Essential oil, Satureja spp., antibacterial activity, Xanthomonas phaseoli pv. phaseoli, Xanthomonas citri subsp. fuscans, bean
