An experiment was conducted to manage the stem and root rot disease of sesame incited by Macrophomina phaseiolina by a combination of new generation fungicides and biocontrol agents. Seven chemicals and a bio-agent, Pseudomonas fluorescens were tested separately in combinations with seed and soil treatments of Trichoderma viride vis-a-vis untreated control. Seed treatment with Trichoderma viride @ 10g/kg +furrow application of T. viride (2.5 kg enriched in 250 kg FYM /ha combined with foliar application of azoxystrobin @ 1ml/l at 45 DAS and 60 DAS was found to be significantly effective in sustaining minimum disease incidence (5.25 %), maximum yield (431.55 kg/ha, 45.05 % increase over control) and highest B:C ratio (1.54). It was followed by seed treatment and furrow application of Trichoderma combined with chemical sprays of carbendazim + mancozeb @ 2.5g/l (6.77 % disease incidence, 417.85 kg/ha of yield, 40.45 % increase in yield over control, B:C ratio of 1.40). All treatments significantly minimized infection and sustained higher seed yield compared to untreated control. Highest incidence (16.21 %) and minimum yield (297.50 kg/ha) were recorded in the untreated crop. Spraying with chemical fungicides was found more effective vis-a-vis bio-control agent, Pseudomonas fluorescens, in managing the disease.
