Collar rot of lentil caused by Sclerotium rolfsii Sacc. is one of the destructive diseases in lentil growing areas of the Madhya Pradesh. In the present work, eight fungicides viz., Captan, Blue copper, Carbendazim, Carbendazim + Mancozeb, Mancozeb, Fipronil, Thiophanate Methyl and Pyraclostrobin and seven plant extracts viz., leaves of Neem, Ashok, Parthenium, Castor, Citrus, Bulb of Onion and Clove of Garlic were evaluated for management of collar rot of lentil under in vitro condition. Garlic clove extract at 15 percent concentration was found best antifungal which completely inhibited the growth and sclerotial production of Sclerotium rolfsi. Onion bulb extract at 10 and 15 percent concentration was also found very promising antifungal for inhibiting the growth and sclerotia production of S. rolfsii. Pyraclostrobin was found best fungicide which completely inhibited the radial growth and sclerotia production of Sclerotium rolfsii. Captan, Carbendazim + Mancozeb and Mancozeb were second next in order of toxicity resulting, 94.11, 82.96 and 66.11 percent inhibition of radial growth and 89.65, 50.13 and 49.10 percent inhibition of sclerotia production, respectively. Thiophanate methyl, Carbendazim, Blue copper and Fipronil were not found effective in inhibiting the growth and sclerotia production of Sclerotium
