Abstract: The trial was conducted subsequently during three years for development of integrated disease management module in rice with main plot treatments consisting of seed treatment (ST) of benomyl (0.3%) followed by Pseudomonas fluorescens (0.5%) and cultural practices (CP) like soil application of rice husk ash (RHA) at sowing on raised beds (1 kg m-2) + soil application of rice straw (RS) @ 2 tones ha-1 at transplanting and no ST and CP together with eight fungicide treatments including absolute control as subplot treatments. The pooled results revealed that the lowest sheath rot (25.02%) and brown spot (11.11) diseases with highest disease reduction of 63.05 and 79.69 per cent, respectively were recorded in the treatment combination of ST + CP with three sprays of propiconazole (0.1%) at 15 days interval starting first spray at disease appearance. Thereby, this treatment produced highest grain (35.57 q/ha) and straw (40.09 q/ha) yield with substantial increase in the grain (101.23%) and straw (93.10%) yields as well as gave higher monitory benefits such as total monetary returns of Rs. 58048.85 ha-1, net profit of Rs. 30905.85 ha-1, and B : C ratio of 2.14. This was followed by ST + CP with sprays of bitertanol (0.25%), carbendazim (0.1%) and tricyclazole (0.10%).
