Effect of newer insecticides against chilli thrips, Scirtothrips dorsalis (Hood)

The field experiment conducted during Kharif 2008-09 and 2009-10 on the evaluation of certain new insecticides indicated that spinosad 0.015% was found most effective in reducing the population of S. dorsalis as well as in increasing yields. It attains highest cost benefit ratio followed by diafenthiuron 0.045%, pymetrozine 0.02% and fipronil 0.01%. Indoxacarb 0.015% and flubendiamide 0.012%. Further flubendiamide recorded the lowest mean% reduction over untreated check indicating their poor efficacy against S. dorsalis on chillies.
