The essential oil of Bunium persicum collected from cultivated sources in the cold desert area of Lahaul-Spiti is described for its antimicrobial, larvicidal, and biting deterrent activities. Additionally, odor characterization is given. The chemical composition of the essential oil was analyzed by simultaneous GC-MS and GC-FID. γ-Terpinene and p-cymene were found to be the major compounds. Antibacterial testing by an agar dilution assay revealed low activity of the oil against all tested bacteria. Antifungal activity was evaluated against Candida albicans as well as three species of the strawberry anthracnose causing plant pathogen Colletotrichum. Bunium persicum essential oil demonstrated antifungal activity against all four pathogens. Biting deterrent activity against Aedes aegypti was greater than the solvent control, but significantly lower than DEET. The essential oil of B. persicum exhibited larvicidal activity with an LC50 value of 58.6 ppm against Ae. aegypti larvae.
