Comparative Efficacy and Economics of Biopesticides and Imidacloprid against Mustard Aphid [Lipaphis erysimi (Kalt.)] (Hemiptera: Aphididae)

The present research study was carried out applying the Randomised Block Design (RBD) approach in three replications during rabi season of 2022–2023 at Central Research farm, NAI, SHUATS, Prayagraj. Results revealed that, among all treatments combination insecticide Metarhizium anisopliae (T7) recorded lowest reduction percent aphid (47.94%), followed by Nisco MECH 333(T6) (53.00%), 333 + Neem oil 5% (T1) (54.63%), (T4) (55.33%), Spinosad 240 EC (T3) (63.94%) and EC+ 5%(T2) (69.37%). Imidacloprid 17.8 SL (T5) (74.77%) most successful treatments, first spray is also significantly more than other treatments. While 17.8% treatment produced a superior yield (18.15 q/ha). With imidacloprid SL(T5) (1:6.43), best economics cost-benefit ratio attained (1:5.96), EC(T3) (1:5.64), (1:5.06), (1:4.87), (1:4.65), (1:4.21), control (1:3.25) yielded financial return.
