Department of Plant Pathology, Naini Agricultural Institute, Sam Higginbottom Univerisity of Agriculture, Technology and Sciences, Prayagraj-211 007 (U.P.) India Online published on 20 July, 2019. Abstract 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.
