Abstract:
The field experiment was conducted in randomized block design with three replications of eight treatments for a crop season of the year i.e. “ Rabi 2015-16 ” at entomological research block of crop research centre, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut - 250110 (U.P.), India. Different insecticides against L. erysimi revealed that all the insecticides were significantly effective in reducing the population of aphids and thus increasing the yield than control. Higher yield ranging between 15.55 to 18.15 q/ha and were proved significantly superior over control (14.17 q/ha). The highest seed yield of 18.15 q/ha was obtained from the imidacloprid 17.8 %SL @ 20 ml a.i/ha treated plot and it was significantly superior over rest of the treatments. Cost benefit ratio from the table that imidacloprid 17.8 %SL @ 20 ml a.i/ha ranked first indicating the maximum return Rs 1: 9.55 per rupee invested followed by dimethoate 30 %EC @ 300 ml a.i/ha, Thiamethoxam 25 % WDG @ 25 g a. i ha.
