Experiment were carried out under field conditions at the at Central research farm, SHUATS, Naini, Allahabad during kharif season of July to November 2016 revealed that among the seven different chemical insecticidal treatment, Among all the treatments Thiomethoxam 25 WP recorded highest reduction of Scirtothrips dorsalis population i.e. (84.14%) which was significantly superior over control followed by Spinosad 45 EC (80.77%), Fipronil 5 EC (76.71%) var. Abamactin 1.8 EC (70.97%), Imidacloprid 17.8 SL (65.12%), Profenophos 50 EC (60.47%) and Cypermethrin 25 EC was least effective among all the treatments. Among all treatments, the highest percent increase in yield over control was obtained from plots treated with Thiomethoxam 25 WP (198.64 q/ha), followed by Spinosad 45 EC (194.23 q/ha). 34.46%), The C: B ratio for all treatments was analyzed and found to be highest in case of Thiomethoxam 25 WP (1:9.09) whereas the lowest in case of Cypermethrin (1:6.59).
