A field experiment was conducted during Kharif (rainy season) 2014 and 2015 at Zonal Agricultural Research Station, V.C. Farm, Mandya, to identify suitable weed management practices for wet (drum)-seeded rice under Southern dry zone of Karnataka. Among the various treatments, pre-emergence application of bensulfuron-methyl 0.6% + pretilachlor 6% GR10 kg/ha fb post-emergence application of bispyribac sodium 25 g/ha at 20 days after sowing (DAS) being on par with weed free check, recorded significantly higher net monetary returns and B: C ratio. Uncontrolled weed growth caused 48.23-50.0% reduction in grain yield of wet (drum)-seeded rice.
