Abstract:

In search for alternative ways of plant disease control, essential oils from aromatic and medicinal plants were studied for their antibacterial properties. In a preliminary evaluation, steam-distilled essential oils from oregano, sweet-flag, caraway, peppermint, common, fern leaf and willow-leaved yarrow field accessions were investigated against growth of phytopathogenic bacteria. The disc-diffusion method was used for the assessment of inhibitory effects of the essential oils. The antibacterial activity tests were conducted in vitro. Essential oil from oregano was found to have the strongest inhibitory effect against tested phytopathogenic bacteria. Less antibacterial effect was found with essential oils from caraway, peppermint, fern-leaf and willow-leaved yarrow,, while the oils from common yarrow and sweet-flag manifested no inhibition. Xanthomonas vesicatoria 67 was the most sensitive to essential oils tested. A weak antibacterial activity was found against some Pseudomonas spp. strains and Erwinia carotovora subsp. carotovora bacteria.
