An experiment was conducted to study influence of physiological parameters like temperature, pH and light period on growth and sporuation of Macrophomina phaseolina, the incident of stem and root rot of sesame. It is found that, the pathogen grew best at neutral pH . pH ( mg) followed by pH 7 ( mg). The temperature of 350 C is best for mycelial growth of M. phaseolina followed by 300 C while no growth was found at lower temperatures. The growth of fungus reduces as the temperature increases or decreases. Growth of pathogen was recorded maximum when exposed to 12hours light and 12 hours dark period. | Adaptability of Macrophomina phaseolina the incident of stem and root rot disease of sesame to different regime of temperature pH and light period
