The study was conducted to describe the cultural characteristics such as colour and texture of the leaf blast pathogen Pyricularia oryzae (Cav.) on different solid media viz., potato dextrose agar, potato carrot agar, Kirchoff’s, medium, Richard’s medium, Sabourad’s medium, Takahashii’s medium, rice leaf extract agar and oat meal agar and liquid media viz., potato dextrose broth, potato carrot broth, Kirchoff’s broth, Richard’s broth, Sabourad’s dextrose broth, Takahashii’s broth and rice leaf extract broth. Among all the solid media the highest mean mycelial growth of the fungus Pyricularia oryzae (Cav.) was recorded on oat meal agar (77.6mm) followed by rice leaf extract (75.9mm) and least mean mycelial growth of the P. oryzae (Cav.) on Sabourad’s media (44.7mm) followed by Takahashii’s media (52.5mm). The maximum mean dry mycelial weight of fungus recorded in Kirchoff’s broth (211.56mg) followed by Richard’s broth (206.3mg) and the least mean dry mycelial weight of fungus recorded in Takahashii’s broth (178.0mg) followed by Sabourad’s broth (179.7mg). In general, among all solid media the oat meal agar media and among all liquid media the Kirchoff’s broth is more appropriate for cultural study of rice blast fungus P. oryzae (Cav.).
