Abstract

A field trail was conducted at Crop Research Farm (CRF) SHUATS Naini, Prayagraj, during kharif 2021 in Randomized block design with seven treatments viz, Imidacloprid 17.8% SL Thiodicarb75%WP,Spinosad 45% SC, Emamectin benzoate 5% SG, Neem oil, Beauveria bassiana 1x108 CFU/ml, Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC and untreated control in three replication. Data were taken on fall armyworm population. The larval population of fall armyworm Spodoptera frugiperda (J.E.Smith) on three, seven and fourteen days after spraying revealed that the treatment Emamectin benzoate 5% SG (5.15) proved to be the most effective treatment followed by Thiodicarb75%WP (6.44), Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC (7.41), Spinosad 45% SC (8.23), Imidacloprid 17.8%SL (8.79), whereas Neem oil 3% (10.24) and B. bassiana 1x108 CFU/ml (10.93) were of least effective against Spodoptera frugiperda. Plot treated with Emamectin benzoate 5% SG showed highest yield (35.31q/ha), followed by Thiodicarb75% WP (34.21q/ha), Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC (32.58q/ha), Spinosad 45% SC (32.08q/ha), Imidacloprid 17.8% SL (31.21qt/ha), Neem oil 3% (29.63q/ha) and B.bassiana 1x108 CFU/ml (28.02), as compared to control (22.44q/ha).
