Place and Duration: A field study was conducted during Kharif 2015 and summer 2016, at Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka, India. Methodology: An investigation comprises of eight treatments and replicated thrice. The weeds which were dominant in trials field are Echinichloa sp. Panicum repens, Leptochloa chinensis, Brachiaria mutica, Digitaria sanguinalis among grasses, Eclipta alba, Ludwigia parviflora and Commelina communis as broad leaf weeds and Cyperus sp. as sedge. Results: Application of Propanil 80% DF @ 4 kg a.i./ha and twice hand weeded check at 30 and 45 days after sowing found significantly (p=0.05) superior over the application of Propanil 80% DF @ 3 kg a.i./ha and rest of the treatments in controlling the weeds in direct seeded rice and increases the grain yield of rice without any phytotoxic effect. Conclusion: Propanil 80% DF @ 3 kg a.i./ha could be recommended for post-emergence application at 10 to 15 days after sowing of paddy crop to achieve effective control of weeds.
