Abstract:

A field experiment was conducted during Kharif 2015 and Summer 2016, at Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka, India, to study the effect of different herbicides for control of weeds in irrigated dry-seeded rice. The dominant weeds in fields were Echinochloa sp. Panicum repens, Cynodon dactylon, Bracharia mutica, Digitarias anguinalis and Leptochloa chinensis among grasses, Eclipta alba,Commelina communis and Ludwigia parviflora as among broad-leaf weeds and Cyperus sp. as sedge. Among herbicidal treatments, post-emergece application of BAS 9548 H (penoxsulam 10 g/l + bentazone 360 g/l SC) 3000 ml/ha recorded significantly higher rice grain yield followed by the application of BAS 9548 (penoxsulam 10 g/l + bentazone 360 g/l SC) 2500 ml/ha and twice hand weeding at 15 and 30 days after sowing (DAS). The maximum B:C ratio was observed in plots treated with BAS 9548 H (penoxsulam 10 g/l + bentazone 360 g/l SC) and twice hand weeded check.
