A field study was conducted during rainy (Kharif) seasons of 2016 and 2017 at Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka, India to study the efficacy of XR-848 benzyl ester + penoxsulam (ready-mix) in managing weeds in dry direct-seeded rice. The dominant weeds in the field were: Echinochloa colona, Panicum repens, Cynodon dactylon, Brachiaria mutica, Digitaria sanguinalis and Leptochloa chinensis among grasses, Eclipta alba, Commelina communis and Ludwigia parviflora among broad-leaved weeds and the sedge, Cyperus iria. The post-emergence application (PoE) of XR-848 benzyl ester + penoxsulam (ready-mix) 48.8 g/ ha significantly reduced weed biomass, recorded higher weed control efficiency and rice grain yield during 2016 and 2017 Kharif seasons. It was on par with XR-848 benzyl ester + penoxsulam (ready-mix) 40.6 g/ha PoE and hand weeding twice at 20 and 40 days after sowing.
