Owing to the great loss of the seedlings due to damping-off disease thus an investigation was conducted under in vitro and in situ to observe the effect of Trichoderma viride, Pseudomonas fluorescens and Azadirachta indica leaf extract against Pythium aphanidermatum Maximum inhibition of mycelial growth of the pathogen by dual culture method was used with T. viride (38.8%) and T. viride + A. indica (32.9%). In situ condition, the maximum germination was recorded in P. flurorescens + A. indica (75.6%). Minimum disease incidence was observed in T. viride (4.0%), whereas maximum root and shoot length were recorded in T. viride + A. indica (2.95 cm) and P. fluorescens (10.03cm), respectively.
Bio-agents, Plant extract, Pythium aphanidermatum, Solanum lycopersicum.
