Abstract: A field experiment entitled “Evaluation of post-emergence application of quizalofop-p-tefuryl (4.41% EC) on groundnut (Arachis hypogaea L.)” was conducted during Kharif 2012 at ARS, Chintamani. The soil of the experimental site was red sandy loam in texture, neutral in reaction and medium in available nitrogen, low in available phosphorus and medium in potassium. The experiment consisted of 12 treatments laid out in RCBD with three replications. The predominant weed flora observed in the experimental field were, Cyperus rotundus, Digitaria marginata, Dactyloctenium aegyptium, Cynodon dactylon, Commelina benghalensis Celosia argentia, Amaranthus viridis. The results revealed that pre-emergence application of pendimethalin @ 1.0 kg a.i. ha^-1 followed by post emergence application of quizalofop-p-tefuryl (4.41% EC) @ 1000 ml ha^-1 at 15 DAS recorded significantly maximum net returns (Rs. 26915 ha^-1) and B:C ratio (1.93) was also high with the same treatment. There was no residual effect of quizalofop-p-tefuryl (4.41% EC) on succeeding finger millet crop.
