Abstract: The main objective of the present study is establishing the chemical composition and minimum concentration of essential oil (EO) extracted from Thymus vulgaris L., T. serpyllum L., and Satureja montana L., which induce the mycelial growth inhibition of Verticillium dahliae and Penicillium aurantiogriseum fungi. In vitro testing on CYGA (chloramphenicol-yeast-glucose-agar) medium, with additional oil at 0.25, 0.5, 1, 5, 10 and 15 mg/L concentrations and inoculated with harvested plugs from a young mycelium, pointed out a different reaction of the fungus depending on the oil types and concetrations used. The minimum concentration that ensure inhibiting of mycelial growth for V. dahliae with significant differences compared to control is 0.25 mg/L for all types of EO. P. aurantiogriseum proved sensitivity at 0.25 mg/L for T. vulgaris, and S. montana EOs and 0.5 mg/L for T. serpyllum EO.
