Abstract:
Dry root rot of clusterbean incited by Macrophomina phaseolina (Tassi) Goid is one of the most severe yield destabilizing factors causing serious yield losses every year. In recent years, Macrophomina phaseolina is becoming more prevalent in agricultural areas where climate change is leading to increased temperatures. An experiment was conducted for fungal isolation, purification, identification of the pathogen and the pathogenicity test for all the twelve isolates proven by using three inoculation techniques. The significant variation in disease symptoms was noticed at 25 days after sowing in isolate MP-BKN to 45 days after sowing in isolate MP-UDZ. It was also revealed that the maximum disease incidence (60.35%) was recorded in seed cum soil inoculation technique followed by soil inoculation techniques (52.45%).
