Antimicrobial activity of essential oil of Thymbra spicata L. var. spicata
was investigated against some economically important plant pathogenic bacte
ria including Erwinia amylovora, Erwinia carotovora pv. carotovora, Claviba
cter michiganensis subsp. michigenensis, Pseudomonas syringae pv. syringae,
Agrobacterium tumefaciens and Xanthomonas axonopodis pv. vesicatoria. Both
contact and volatile phase effects of different doses of the essential oil
were determined by using two different methods in vitro. Minimum Bacterici
dal Concentrations (MBC) of the essential oil for E. amylovora, E. c. carot
ovora, C. m. michigenensis, P. s. syringae, A. tumefaciens and X, a. vesica
toria in the determination of the contact effect were 276, 413, 405, 344, 3
28 and 323 mg/ml, respectively. MBCs of the volatile phase of the essential
oil for E. amylovora, E, c. carotovora, C. m. michigenensis, P. s. syringa
e, A. tumefacians and X. a. vesicatoria were 51, 563, 91, 684, 98 and 41 mg
/ml air, respectively. With exception to E, c. carotovora and P. s, syringa
e, the volatile phase oil was found to be more toxic to the test bacteria.
