Abstract

Studies were conducted in a greenhouse to assess the efficacy of Trichoderma viride Pers. Gray and neem cake in different problems soils viz., sandy, black hard pan, saline, sodic, alkaline, red crusted soil, acid soil and normal soil in suppressing the growth of blackgram root rot pathogen Macrophomina phaseolina (Tassi.) Goid. The biocontrol efficacy of T. viride I3, plus neem cake application in uninfested soil was the maximum 60 days after inoculation in acid soil which showed the minimum (5.63%) root rot incidence as compared to T. viride I3, alone (6.44%) and neem cake application alone (7.15%). In infested soil, the T. viride I3 and neem cake plus pathogen inoculation recorded the minimum (6.47%) disease incidence in acid soil as compared to T. viride I3, and pathogen inoculation (7.52%), and neem cake application plus pathogen inoculation (8.72%), In uninocuiated control and in inoculated control of acid soil, the root rot incidence was 7.84 and 9.70 percent, respectively.
