Abstract

Fire Blight caused by Erwinia amylovora is a disease of plants belonging to Rosaceae family of 39 different genera and 128 species. Integrated disease management is preferred by combining different methods in the disease control. Nowadays, studies on alternative methods to control of the disease were intensified. One of these methods is using of essential oils obtained from medical and aromatic plants. In this study, antibacterial activity of 16 different plant essential oil was investigated against to Erwinia amylovora in vitro conditions. Seven essential oils (Allium sativum, Cinnamomi ceylanici, Cymbopogon citratus, Lavandula officinalis, Mentha arvensis, Syzygium aromaticum and Thymus vulgaris) inhibited successfully the growth of Erwinia amylovora in vitro conditions. The higher antibacterial efficacy was produced by the six plant essential oil except Cymbopogon citratus, compared to streptomycin. Essential oils from A Ilium sativum, Cinnamomi ceylanici and Mentha arvensis were obtained in 16.44, 15.11 and 12.94 mm inhibition zones, respectively and these essential oils had the highest antibacterial effects. These effective essential oils was found as promising in this disease control.
