Abstract: Stem and root rot disease caused by Macrophomina phaseolina is the serious soil-borne disease which affects sesame production. To know the best fungicides to manage it, fifteen chemicals were screened in vitro at four concentrations such as 100 ppm, 250 ppm, 500 ppm and 1000 ppm employing poison food technique. Experiment revealed that all the fungicides were strongly inhibited the growth of Macrophomina phaseolina and there was a significant decrease in mycelial growth with an increase in concentration of fungicides. Carbendazim 63%w/w + Mancozeb 12% w/w recorded maximum mycelium inhibition (70.10%) at 100 ppm followed by Thiophanate methyl 70% WP. At 250 ppm, Carbendazim 63%w/w + Mancozeb 12% w/w registered maximum inhibition (86.27%) followed by Thiophenate methyl 70% WP (84.61%) and Tebuconazole + Trifloxystrobin (84.61%). The complete inhibition (100%) of M. phaseolina mycelium at 500 ppm was observed in Carbendazim 50% WP, Carbendazim 63%w/w + Mancozeb 12% w/w, Hexaconazole 5% EC, Propiconazole 25% EC, Thiophenate methyl 70% WP and Carboxin 37.5%WP+ Thiram 37.5% followed by Tebuconazole + Trifloxystrobin(99.60%). At 1000ppm all the fungicides gave more than 90% inhibition where as Carbendazim 50% Wp, Carbendazim 63%w/w + Mancozeb 12% w/w, Hexaconazole 5% EC, Propiconazole 25% EC, Thiophanate methyl 70% WP and Carboxin 37.5%WP+ Thiram 37.5%, Propineb 70% WP, Tebuconazole + Trifloxystrobin and Tebuconazole 25% w/w gave complete inhibition.
