Abstract: The aim of this study is to investigate preliminary antifungal activity of three essential oils by disc diffusion method, the essential oils of three plants used in traditional Sudanese medicine namely Mentha spicata (Lamiaceae), Cymbopogon schoenanthus L. (Poaceae), and Citrus reticulata (Rutaceae), was evaluated for their ability to inhibit the growth of selected phytopathogenic fungi Fusarium oxysporum f. sp. ciceris (causing wilt in chick pea) and the standard fungi Aspergillus niger was used for comparison. Essential oils were extracted by hydrodistilation using Clevenger apparatus. The experiment was carried out using disc diffusion method in different concentrations of essential oil on PDA culture at 25°C. The result showed essential oil of studied plants in all concentrations had completely inhibited growth for tested fungi.Abstract: The aim of this study is to investigate preliminary antifungal activity of three essential oils by disc diffusion method, the essential oils of three plants used in traditional Sudanese medicine namely Mentha spicata (Lamiaceae), Cymbopogon schoenanthus L.
