Experiments were conducted to evaluate new fungicide fenamidone + mancozeb at three different concentrations for its efficacy against Pythium aphanidermatum (Edson) Fitzpatrick, the incitant of damping off disease, to select the most effective concentration for the management of the disease. Three fungicides were tested in vitro by poisoned food technique for their efficacy to inhibit mycelial growth of the pathogen. Fenamidone 10% + mancozeb 50% inhibited cent per cent mycelia growth at all the concentrations. Among the three fungicides tested under field conditions, fenamidone 10% + mancozeb 50% @ 0.3% was found to be the most effective dose in tobacco nurseries which could reduce the disease to an extent of 96.8 per cent with a corresponding maximum healthy transplantable seedlings (856 / sq. m.) when applied as a drench on the nursery beds at the time of sowing @ 0.1% followed by foliar spray @ 0.3% twice at 25 and 35 DAS. Metalaxyl 8% + mancozeb 64% when sprayed at 10 days interval could protect 95.6 per cent seedlings with a production of 793 / sq. m of healthy seedlings.
