Dry root rot disease hinders the cultivation of groundnut crop and leads to major yield loss. Chemical control of this pathogen renders harmful effect on soil microbes thereby depleting the soil quality. Considering this, an attempt was made to manage groundnut dry root rot disease in a natural way. Different oil cake extracts were tested for their antifungal activity against groundnut dry root rot pathogen Macrophomina phaseolina through poisoned food technique. Among the seven oil cake extracts tested under in vitro condition, neem cake extract found effective against Macrophomina phaseolina with minimum mycelial growth of 4.23cm and maximum mycelia inhibition of 52.90 per cent followed by coconut cake extract recorded mycelial growth of 4.47 cm and mycelial inhibition of 50.33 per cent against control at 10 per cent concentration. But under 15 per cent concentration, groundnut cake extract was proved effective against Macrophomina phaseolina with minimum mycelial growth of 3.20 cm and maximum mycelial inhibition of 65.00 per cent followed by neem cake extract recorded the mycelial growth of 4.40 cm and mycelial inhibition of 51.10 per cent.
