Abstract :
The field experiment conducted during Kharif 2008-09 and 2009-10 on evaluation of certain new insecticides indicated that spinosad 0.015 per cent 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 per cent reduction over untreated check indicating their poor efficacy against S. dorsalis on chillies.
