Abstract:
Mungbean is sensitive to a variety of fungal, bacterial and viral diseases. Root rot of caused by Macrophomina phaseolina is considered as the most serious disease, particularly in all the mungbean cultivating areas of Rajasthan and India. Due to favorable weather circumstances, the disease spread widely across the state and resulting in significant yield losses. In the present study influence of various temperature, pH and humidity levels were studied on the growth of the pathogen. Maximum mycelial growth (90mm) was observed at 30 oC temperature and at 80% relative humidity and maximum dry mycelial weight (615 mg) was observed at 6.5 pH. Thirteen cultivars of mungbean were tested through artificial inoculation in pot condition, against root rot of mungbean. None of variety was found immune or resistant to root rot pathogen. Cultivars, RMG-1140, RMG-1144, RMG-1086, RMG-1079 were observed susceptible and RMG-1132 and Check were found highly susceptible for the disease.
