Abstract: A field experiment entitled "Studies on novel herbicides and their combination on effective weed control in direct seeded Rice (DSR) in Southern Transition Zone of Karnataka" was conducted during kharif 2018 at College of Agiculture, Navile, University of Agricultural and Horticultural Sciences, Shivamogga with seven treatment combination that include inter cultivation. Four hand weeding practices at 15 days interval. Herbicides (pretilachlor 30.7 EC, Pyrazo sulfuron ethyl 20% WG, Bensulfuron methyl 0.60 % + Pretilachlor 6% GR (Pre.em.-3 DAS) and pre-emergent along with post-emergent (Pre em. and post em.,) herbicides viz., Metsulfuron-methyl (Pre.em.-3 DAS). and weedy check were included and the experiment was laid out in RCBD with three replication. The experimental results revealed that four hand weeding at 15 days interval recorded higher grain yield (5418 kg ha-1) and straw yield (6105 kg ha-1) as well as growth attributes. These results are on par with inter cultivation fb Hand weeding at 20 and 40 DAS and bensulfuron methyl 0.60 % + Pretilachlor 6% GR (Pre.em.-3 DAS) recorded higher growth and yield attributes without being phytotoxic to the crop.
