Charcoal rot of sorghum caused by Macrophomina phaseolina is a disease of economic importance for which a high level of genetic resistance is not available. Therefore, an effort was made to manage this disease with potent rhizobacterial strains viz., AUDP 139 and AUDT 801 in CSV 8R and CSV 29R cultivars. In CSV 8R, seed soaked in supernatants of AUDP 139 for two hours recorded least charcoal rot incidence of 40.58 % with highest yield of 1924.90 Kg/ha whereas in CSV 29R, seed treatment with AUDT 801 + AUDP 139 @ 3g/Kg of seeds recorded least disease incidence of 14.23 % with highest yield of 2675.73 Kg/ha. It is inferred that the use of selection of effective strains of rhizobacteria can be a useful component of integrated management of charcoal rot in sorghum. | In vivo analysis of rhizobacteria and their supernatants for control of charcoal rot of sorghum
