The present study dealt with the assessment of antifungal activities of acetone, ethanol, methanol and chloroform leaf and fruit extracts of Aegle marmelos, Syzygium cumini and Pongamia pinnata against the soil borne fungi, Pythium debaryanum. Maximum inhibition of fungal growth was found with methanol extract of A. marmelos leaves and fruits. At 1 ml concentration (C4), complete inhibition of mycelial growth of P. debaryanum was observed with extract S3P1 (100%), followed by S3P3 (97.63%) and S2P1 (95.21%). Lowest inhibition was oberved with S4P2 (75.40%). Pot culture study revealed that tomato seed treatment with Pseudomonas fluorescens (10 g/kg)+Trichoderma viride (4 g/kg)+methanol extract of A. marmelos 4% was effective to control pre and post emergence damping off caused by P. debaryanum. The methanol extract revealed strongest antifungal activity against P. debaryanum, followed by ethanol extract and lowest antifungal activity was found in chloroform extract.
