Abstract:
The field experiment was conducted at University of Agricultural Sciences, Bangalore, during kharif 2018. Experiment consists of application of three post emergent herbicide molecules (Fomesafen, Propaquizafop and Imazethapyr) and their combinations at 20 DAS, Major weeds observed were, Ageratum conyzoides, Achyranthes aspera, Alternanthra sessilis, Borreria articularis, Dactyloctenium aegyptium, Echinochloa colonum, Cynodon dactylon, Eleusine indica and Cyperus rotundus. Post-emergent application of Fomesafen 18.8% SL+ Propaquizafop 5.83% EC @ (252+78) g a.i. ha^-1 recoded significantly lower weed density, weed dry weight, and higher weed control efficiency at all stages of the crop, resulting in superior grain yield and lower weed index (1290 kg ha^-1 and 10.23) and it was on par with Fomesafen 18.8% SL + Propaquizafop 5.83% EC @ (210+65) g a.i. ha^-1 (1248 kg ha^-1, 13.15 respectively).
