Abstract: Weeds are the major biotic stresses for finger millet cultivation. Initial slow growth of the finger millet favours weed growth. Echinochloa colona among grasses, Cyperus iria among sedges and Alternanthera triandra, Eclipta alba and Phyllanthus urinaria among broad leaf weeds were dominant. Weed index (loss of yield due to weeds) was found to be minimum with application of ethoxysulfuron (34.37 %). The maximum weed index was found with application of fenoxaprop-p- ethyl (93.62 %) at higher level (45.0 g ha-1). In the experimental field, the most dominant species was Echinochloa colona which ranged between 24-46 per cent at all the growth stages. It was followed by Phyllanthus urinaria (13-18 %), Eclipta alba (5-26 %), Cyperus iria (3-23%) and Alternanthera triandra (5-12 %).There was complete control of broad leaf weeds viz. Alternanthera triandra, Eclipta alba and Phyllanthus urinaria and sedges i.e. Cyperus iria by the application of metsulfuron methyl + chlorimuron ethyl and ethoxysulfuron, where as grassy weed i.e. Echinochloa colona was completely killed by the application of fenoxaprop-p-ethyl and showed 100% weed control efficiency, respectively. Hand weeding twice recorded the highest grain yield and net return. Application of ethoxysulfuron registered the highest B:C ratio which was at par with metsulfuron methyl + chlorimuron ethyl and hand weeding twice.
