Abstract
Present study was carried out to examine the biological potential of different fungal and bacterial antagonists viz., Trichoderma harzianum, T. reesei, Aspergillus niger and Bacillus subtilis in management of root-rot disease caused by Macrophomina phaseolina and on the growth parameters of mungbean under pot condition. From the results, it was evident that the microbial antagonists significantly suppressed the root-rot disease (27-51%) and improved the growth and yield of mungbean. However, the root-rot fungus caused excessive rotting of roots and stunting of plant growth in the untreated plants. Among the tested biological control agents against M. phaseolina, T. harzianum was found to be the most effective against the fungus and resulted in 51% decrease in the root-rot severity and 31% increase in the yield, followed by B. subtilis. Root-rot infection significantly reduced functional root nodules by 58%. Biochemical components viz., total chlorophyll, total carotenoid and leghaemoglobin content was also decreased by 48, 38 and 25%, respectively, in the root-rot fungus infected plants. However, treatment with the biological control agents significantly increased the biochemical components as well as root nodulation in the order T. harzianum>B. subtilis>T. reesei>A. niger. Soil population of M. phaseolina in untreated pots increased exponentially but the increase was 30-66% less in the pots treated with biological control agents. The study has clearly demonstrated that these microbial antagonists specially, T. harzianum and B. subtilis significantly managed the root-rot disease as well as improved the plant growth and yield of mungbean.
