N2 - The increasing recognition and importance of phytopathogenic fungi, the difficulties encountered in their control and the increase in resistance to antifungal have stimulated the search for natural alternatives. The antifungal effects of essential oils and their compounds were investigated on mycelial growth inhibition bioassays oiFusarium oxysporum f. sp. gladioli. The essential oils have been used empirically. In general, a significant antifungal effect was observed with Cinnamomum zeylanicum, Thymus vulgaris and Syzygium aromaticum oils which had total inhibition at 100, 150, 200, 250 and 300 ppm. Teloxys ambrosioides, Mentha piperita and Citrus aurantifolia oils exhibited a dose dependent inhibition on mycelial growth to increase the dose of 100 at 300 ppm. While Allium sativum, Capsicum sp., Ruta chalepensis and Eucalyptus globulus oils had no antifungal activity at different concentration tested. All compounds with the exception of cineole had a fungicide or fungistatic effect.
