Charcoal rot of sorghum causing M. phaseolina is one of the most prevalent disease of sorghum in India. We have tested growth of pathogen at different levels of temperature and pH. The maximum growth of pathogen was observed at 350C after 72 hrs of incubation and clearly indicates that isolates preference towards higher temperature. However, the maximum dry mycelia weight at pH 6.0 shows significantly superior over other pH levels tested. The results show the growth of pathogen was more at high temperature and low pH.
