Abstract
The field experiment was carried out in the Rabi season of 2022-2023 at Central Research Farm (CRF), Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj. The field was replicated with three randomised block design (RBD) of eight treatments including control (water spray) viz., Indoxacarb 14.5% SC, Chlorantraniliprole 18.5% SC, Emamectin benzoate 5% SG, Emamectin benzoate 5% SG+Indoxacarb14.5% SC, Beauveria bassiana 1.5% WP, NSKE 5%, Neem oil 5% and one control plot (water spray). The maximum reduction of larval population was recorded in T3 Emamectin benzoate 5% SG (78.9%) followed by T2 Chlorantraniliprole 18.5% SC (76.2%), T4 Emamectin benzoate 5% SG + Indoxacarb 14.5% SC (68.2%), T1 Indoxacarb 14.5% SC (65.8%), T6 NSKE 5% (59.3%), T5 Beauveria bassiana 1×108CFU\G (54.7%) was found next effective treatments. Among all the treatments T7 Neem oil 5% (49.4%) was found least effective but comparatively superior over untreated plot (0%).
