Biologically effective dose of sodium acifluorfen + clodinofop-propargyl applied as post emergent for weed management in greengram

Field experiments were conducted during Kharif 2015 and Summer 2016 at AICRP for Agro-forestry, University of Agricultural Sciences, GKVK, Bengaluru. The experiments were laid out in RCBD with three replications comprising of seven treatments. Major weed species observed were Cyperus rotundus, Eleuisine indica, Dactyloctenium aegyptium, Borreria articularis, Echinochloa colona, Commelina benghalensis, Euphorbia geniculata, Phyllanthus nirurietc., Theresults revealed that post emergence application of sodium acifluorfen 16.5% + clodinofop-propargyl 8% EC @ 206.25 + 100 g a.i., at 22 DAS recorded significantly higher grain yield (1145 kg ha-1) and haulm yield (1650 kg ha-1), followed by sodium acifluorfen 16.5% + clodinofop-propargyl 8% EC @ 165 + 80 g a.i., (968 kg ha-1 and 1377 kg ha-1, respectively)with 87.92 per cent weed control efficiency when compared to weedy check (460kg ha-1 and 731 kg ha-1, respectively)with no phytotoxicity effect on succeeding crop (Finger millet)
