Abstract:
Mungbean [Vigna radiata (L.) Wilczek] also referred to as ‘golden gram’ and is affected by number of diseases, of which the root rot is the one of serious diseases caused by Macrophomina phaseolina. Experiment was conducted in kharif 2017 at Department of Plant Pathology, SKN College of Agriculture, Jobner, Jaipur (Rajasthan). In this study four bio-control agents were evaluated for their antagonistic ability to suppress the growth of Macrophomina phaseolina both in the laboratory and pot conditions (Seed treatment, FYM enriched soil treatment and seed-cum-soil treatment of BCA). Five different soil amendments were used to examine their capacity to reduce the root rot disease incidence in pot conditions. Among the tested antagonists, Trichoderma harzianum showed maximum mycelial growth inhibition (83.55%) of the pathogen, followed by Trichoderma viride (78.11%) in in vitro condition. In pot conditions maximum disease control was recorded with seed-cum-soil application of T. harzianum (78.22 and 75.99%) followed by T. viride (72.22 and 70.21%) over control (54.80 and 63.85%) at 40 and 60 days after sowing, respectively. In soil amendments maximum disease control was recorded with neem cake (77.93 and 75.88%), followed by mustard cake (67.87 and 65.60%) over control at 40 and 60 days after sowing, respectively.
