Abstract: The essential oils of different species of Ocimum L. (Lamiaceae) collected from different locations of Uttarakhand were studied for their antifungal activity against a plant pathogenic fungus, Rhizoctonia solani by disc diffusion method and their MIC (Minimum inhibitory concentration) was calculated by broth microdilution method. Essential oils of all the eight accessions exhibited different degree of antifungal activity against the tested fungus. The essential oil of Ocimum basilicum L. (Lemon basil) exhibited maximum inhibitory effect with MIC of 31. 25 µg/mL. However, Ocimum sanctum L. (Sri tulsi) and Ocimum gratissimum L. (Clove basil) exhibited strong inhibitory effects with the MIC of 62.5 µg/mL. In contrast Ocimum kilimandscharicum Guerke (Camphor basil), Ocimum sanctum L. (Krishna tulsi), Ocimum basilicum L. (Van tulsi) exhibited moderate inhibitory effect with the MIC of 125-250 µg/mL. The weakest antifungal activity was exhibited by the O. sanctum (Shri Tulsi) and O. americanum L. (Spice basil) with MIC of 500 µg/mL. It can be concluded from this study that the essential oils of different Ocimum species can be used as a potent natural antifungal agents.
