Field experiment was conducted at Regional Research Station, Karnal (Haryana) on cowpea during Kharif, 2011 and 2012. In pooled result flubendiamide @ 1.0 gm/lit was found significantly better to reduce the cowpea pod borer damage on number basis (19.61%) followed by indoxacarb 14.5 SC @ 0.5ml/lit (24.13%). Similarly highest marketable yield (96.12q/ha) was recorded in flubendiamide @ 1.0 gm/ lit and found to be at par with indoxacarb 14.5SC @ 0.5ml/lit (90.36). However, maximum cost benefit ratio (1:14.5) was recorded in endosulfan 35 EC @ 2ml/lit followed by indoxacarb 14.5SC @ 0.5ml/lt. (1:5.0) and thiodicarb 40 WP @ 1.0 gm/lit (1:3.7). So based on the efficacy, flubendiamide @ 1.0 gm/lit followed by indoxacarb 14.5SC @ 0.5ml/lit was found to be very effective against Maruca vitrata in cowpea.
