Abstract:

The charcoal rot of Black gram caused by Macrophomina phaseolina (Tassi) Goid. is an important disease affecting Black gram production areas in India. Although considerable research related to the biology and ecology of Macrophomina has been conducted, it continues to cause huge economic losses in many crops. No single control measures are effective or not feasible under farmer’s conditions. In this study, two bio-control agents, Trichoderma viride and Pseudomonas fluorescens were assessed for their ability to reduce the growth of M. phaseolina under laboratory conditions. It was found that among the antagonists tested, Trichoderma exhibited strong inhibition (77.77%) against M. phaseolina. Their culture filtrates were also found to be effective in promoting the in vitro growth. The maximum seed germination (97%), shoot length (22.2cm) and root length (16.5cm) was recorded in the seed treatment of Trichoderma followed by Pseudomonas in the decreasing merit. In addition to the use of the bio-control agents, fungicide Carbendazim was also applied as seed treatment at recommended doses. The results indicated that Carbendazim @ 0.1% was very effective in the management of root rot disease which effectively controlled the mycelial growth.
