A field study was conducted during Kharif 2014 and Kharif 2015 to evaluate the bioefficacy of fungicides (both solo and combination products) against stem rot disease of paddy. Different fungicides were tested either as seed treatment (ST), seedling dip (SD), foliar spray (FS) or in combinations. Disease was measured in 0-9 standard evaluation scale and scores were transformed into percent disease index (PDI). PDI of Kharif 2014 and Kharif 2015 were pooled to get the mean PDI. Among the different treatments, ST with carbendazim at 2g/kg of seed + FS with Thifluzamide 24 SC (0.75 ml/l) have recorded lowest PDI of 15.15 (mean PDI) which was on par with another treatment comprises ST with carbendazim at 2g/kg of seed + FS with Thiophanate Methyl 70 WP at 1.5 g/l (mean PDI 18.7). Significant increase in grain yield (51.6 q/h) was observed in the plots having treatment combination of ST with carbendazim at 2g/kg of seed + FS with Thifluzamide 24 SC (0.75 ml/l) which was statistically on par with another treatment comprises ST with carbendazim at 2g/kg of seed + FS with Thiophanate Methyl 70 WP at 1.5 g/l (50.3 q/h) whereas, other treatments recorded the yield in the range of 34.8-44.6 q/ha.
