Evaluation of Bioagents Against Seed Borne Fungi in Green Gram and Blackgram

摘要

An experiment was conducted 2011-2012 in vitro the effect of different antagonists viz. Tricho-derma viride, Pseudomonas fluorescens and Bacillus subtilis were evaluated against different seed borne fungi of green gram and black gram by dual culture technique. Among three bioagents, Bacillus subtilis exhibited maximum mycelial growth inhibition of Phoma medicaginis (73.70%), Fusarium solani (57.60%),Fusarium oxysporum (47.82%) and Macrophomina phaseolina (47.29%) followed by Pseudomonas fluorescens exhibited maximum mycelial growth inhibition of Phoma medicaginis (71.70%), Macrophomina phaseolina (62.41%) Fusarium oxysporum (59.97%) and Curvularia lunata (41.08%) respectively and lowest mycelial growth observed in Phoma medicaginis (68.33%), Macrophomina phaseolina (44.94%), Fusarium solani (38.95%) with Trichoderma viride.
