Abstract
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.
