In: Annals of Agricultural Science 2002.v.47(3)Summary: Antifungal activity of essential oils, from 8 plant namely, Dill (Anethum grave- olens), Geranium (Pelargonium graveolens) , Coriander (Coriandram sativum), Sweet basil (Ocimum basilicum), Thyme (Thymus vulgaris), Marjoram (Majorana horensis), Mint (Mentha peperita) and Cumin (Cuminum cyminum) were evaluated against certain pathogenic fungi: M.phaseolina, S.rolfsii, F. solani, R.solani and Pythium sp. which causing cotton seedling damping- off disease. In vitro tests es- sential oils revealed antifungal activity against the tested fungi. Higher antifungal activities were recorded with thyme, cumin and mint essential oils . The mycelial growth of certain fungi were completely inhibited with cumin ( M.phaseolina. S.rolfsii and R.solani ) and mint (S.rolfsii and Pythium sp.) essential oils, whereas thyme caused complete inhibition of all the tested fungi . The vapours of the tested essential oils exhibited almost similar influence after different periods from incubation. VapourS of thyme, cumin and mint essential oils completely suppressed the mycelial growth of tested fungi, except with mint oil against F. solani which caused only 75.52% of inhibition.
