Sesame root rot is caused by M. phaseolina also one of the major factor of sesame production constrain. Hence, the present study was conducted with an objective to assess the prevalence and incidence of root rot disease in different locations of cuddalore district, Tamil Nadu, India during 2017 and assess the cultural characters and pathogenic variability among the isolates of M. phaseolina. The survey clearly revealed that the disease incidence ranged from 13.60 to 34.65 per cent showing the endemic nature of the disease. Among the isolates MP4 was found as the most virulent which recorded maximum percent disease incidence (46.65%) on sesame variety PKM 3 with artificial inoculation. Also, the same isolate was found to be as best in radial growth (90.00), mycelial character (Black profusely aerial growth) and sclerotial characters viz., size (104.18 µ) and number (188.46) of sclerotia.
