The present paper reports the antifungal activity of plant extracts (5 % Concentration) from seven plant species viz., Bougainvillea spectabilis, Zingiber officinali, Datura stramonium, Curcuma longa, Ocimum sanctum, Hibiscus bombycideron, Tegetes erecta. Antifungal activity was tested against Macrophomina phaseolina. All plant extracts (sterilized and unsterilized) exhibited considerable distinction in radial mycelial growth of tested pathogen. Overall, Curcuma longa appeared significantly the most effective and suppressed the radial mycelial growth (sterilized plant extract, 47.13% and unsterilized plant extract, 48.28 %) of the Macrophomina phaseolina. However, Ocimum sanctum exhibited minimum inhibition (sterilized plant extract, 25.29 % and unsterilized plant extract, 22.99 %) against Macrophomina phaseolina. It may be concluded from the present investigation that Curcuma longa can be utilized for the management of Macrophomina phaseolina.
