The leaf extract of Solanum torvum Sw. (Solanaceae) was evaluated for its fungitoxic activity against Fusarium sacchari (E.J. Butler & Hafiz Khan) W. Gams (1971). The leaf extract was found to inhibit completely the mycelial growth of the test fungus at minimum 0.5 ml/ml dose by the poisoned food technique. The nature of the extract was fungicidal at 0.5 ml/ml dose, since no further revival of growth was observed in inoculated plates even after incubation for 6 days after inoculation. The extract required minimally 5 min to kill the test fungus at its MIC. The extract also inhibited the growth of 12 other pathogenic fungi as well as 2 pathogenic strains of bacteria under test. It was found to be non-phytotoxic in nature and to show antifungal activity under in vivo conditions.Keywords:
