Nine antagonists were screened for the antagonistic effect against tomato stem rot pathogen. In vitro studies showed that the Bacillus subtilis and Pseudomonas fluorescens were highly significant in inhibiting the mycelial growth and sclerotial production of the pathogen. Next to these two antagonists, Trichoderma karcianum and T. viride were effective in reducing the sclerotial size and germinatin. Pot culture studies indicated that the soil amendment with T. hurzianum resulted in better plant stand upto 80 per cent at 60 DAS followed by T. viride and P. fluorescens.
