Twelve seed samples of rice were tested and all were found infected by Bipolaris oryzae the cause of brown spot disease. Highest (5.5%) and lowest (1.5%) incidence was found in sample of Bhabokhali and Mahozompur, respectively. Four plant extracts viz. biskatali (Polygonum hydropiper), onion (Allium cepa), garlic (Allium sativum) and neem (Azadirachta indica) were evaluated against Bipolaris oryzae. Among the plant extracts, neem and garlic were the most effective against Bipolaris oryzae at 1:1 dilution. All other plant extracts were also effective against Bipolaris oryzae at higher concentrations.
