In vitro experiments were conducted in the Plant Pathology Laboratory, Agrotechnology Discipline, Khulna University, to evaluate the variable effects of some selected fungicides against some Bipolaris sorokiniana isolates collected from different regions of Bangladesh. Four fungicides namely mancozeb, carbendazim, propiconazoole and copper oxychloride was used in the study. No mycelial growth was found even at the lowest concentration of propiconazole after 7 days of inoculation in all isolates of B. sorokiniana. Application of 300 ppm of copper oxychloride, carbendazim and mancozeb decreased radial mycelial growth after 7 and completely inhibited at higher concentrations after 12 days of inoculation. The results revealed that inhibition percentages were increase with the increased in concentration of all fungicides used in this study.
