Aqueous extracts and essential oils of Thymbra spicata, Satureja thymbra, Laura nobilis, Mentha spicata, Salvia fruticosa and Inula viscosa exhibited fungitoxicity against four phytopathogenic fungi. The essential oils of T. spicata and S. thymbra were most effective in inhibiting mycelial growth of the test fungi with minimum inhibitory concentrations between 400 and 800 mg/l medium. The volatile phase of the essential oils was also effective. The essential oils were more toxic against Phytophthora capsici than the fungicides carbendazim and pentachlornitrobenzene. Investigations with thin-layer chromatography implicated thymol and carvacrol as active compounds.
