Ethanolic extracts of twenty-one plant species were tested in vitro for their fungitoxic properties against leaf spot causing pathogen of mulberry Myrothecium roridum by poisoned food technique. Ethanolic extracts of twenty-plant spp. reduced mycelial growth of M. roridum significantly except E. pulcherrima. Highest inhibition of M. roridum colony growth observed in 10% extracts of E. citriodora (49.45%) followed by D. metel (39.45%), Chromolaena odoratum (25.56%) and A. sativum (25.00%). Among the concentration tested, 10% concentration was found significantly higher effective on reducing colony growth followed by 5 and 2.5%. Aqueous extract fresh leaves/bulb of seven short-listed plant spp. (inhibition>15% in ethanolic extracts) revealed that D. metel inhibited (23.43%) followed by E. citriodora (14.66%), C. odoratum (13.53%). On dry leaf extracts D. metel was found more effective than E. citriodora. The results indicated that D. metel, E. citriodora, C. odoratum and A. sativum having high fungitoxicity against M. roridum and ethanolic extract found more effective than aqueous extract.
