Bio-control options for management of rhizome rot and wilt disease complex of ginger in Terai agro-ecological region

Among the different isolates of Trichoderma tested, Trpun (Trichoderma Pundibari isolate) showed the highest growth inhibition against Fusarium solani (50%) and Fusarium moniliforme (59%) in in vitro. Application of bio-agent consortia i.e. both Pseudomonas fluorescens and Trichoderma Pundibari isolate as seed and well as soil treatment showed improved plant vigour by producing highest dry weight of plant (27.90 g) as compared to other treatments. Maximwn disease reduction of 82.7% over control was found when rhizome and soil were treated with Pseudomonasjluorescens and Trichoderma Pundibari isolate combination. This treatment also produced the highest yield of 5.47 kg/plot.
