  • S.T. Hindu College, PG Department of Botany, Tamil Nadu, 629 002, India


Trichoderma viride, T. harzianum, Laetisaria arvalis and other eight isolates of Trichoderma viride, isolated locally. were tested in vitro for their antagonistic activity against Pythium indicum. the causal organism of danlping-off of tomato, by dual agar technique. Among the fungal antagonists tested, Trichoderma viride was found highly inhibitory to P. indicllm. Volatile and non-volatile antibiotics of T. viride inhibited the in vitro growth of P. indicum significantly.
