A total of 90 fields from five districts covering ten tehsils with 30 villages of Rajasthan were surveyed. The survey results revealed that the dry root rot caused by Macrophomina phaseolina is an important pathological problem, mainly in clusterbean growing districts and dry root rot incidence appeared in all the surveyed districts. Dry root rot infected plants appeared in patches in all the affected fields. The mean maximum dry root rot incidence was recorded in Bikaner (25.52%) followed by Churu (22.39%), Sikar (21.09%), Jaipur (18.39%) and Jhunjhunu (17.50%) district. The disease incidence appeared in patches in all the affected fields during the survey wherever clusterbean crop has been grown regularly. The results of the study also revealed that per cent dry root rot incidence varied from location to location and variety to variety. As compare to improved varieties, local varieties were found to be more susceptible to infection of M. phaseolina. Variation in dry root rot incidence was also observed among the soil types. Sandy soils were more conducive to the pathogen M. phaseolina.
