The study was conducted to describe the growth characteristics of the leaf blast pathogen Pyricularia oryzae isolates on different solid media viz., Host Extract Agar (HEA), Oat Meal Agar (OMA), Potato dextrose agar, Richard’s Agar medium. Among all the solid media the highest mean mycelial growth of the fungus Pyricularia oryzae was recorded on Host Extract Agar ( cm) followed by Oat meal agar ( cm) and least mean mycelial growth of the P. oryzae on Richard’s agar media (). In general, among all solid media the Potato Dextrose Agar media is more appropriate for cultural and morphological study of rice blast fungus P. oryzae. | Effect of different culture media on the growth and development of Pyricularia oryzae from different rice growing regions of Karnataka
