Field Efficacy and Economics Certain Chemicals and Botanical against Fall Armyworm, [(Spodoptera frugiperda (J.E. smith.)] on Maize (Zea mays)

Abstract

The current study evaluated the field efficacy of specific chemicals and botanicals against fall armyworm (Spodoptera frugiperda) on maize (Zea mays Linn.) during the Kharif season of 2023. It was carried out in a RBD with 3 replications and 8 treatments (seven insecticides and one control). Chlorantraniliprole 18.5% SC (3.25) > Spinosad 45 SC (3.46) was the study's most effective treatment. Lambda-cyhalothrin 5% EC + Chlorantraniliprole 18.5% SC (3.99) was the next best treatment, followed by Emamecttin benzoate 5% SG (4.16) > Lambda-cyhalothrin 5% EC (4.44) > Flubendiamid 39.35% SC (4.87) > Neem oil 1500 ppm (5.18), which was the least effective but still significantly better than the control. In comparison to the untreated Control plot (1:1.52), the most cost-effective treatment was Chlorantraniliprole 18.5% SC (1:2.96), followed by Spinosad 45 SC (1:2.82), Lambda-cyhalothrin 5% EC + Chlorantraniliprole 18.5% SC (1:2.65), Emamecttin benzoate 5% SG (1:2.53), Lambda-cyhalothrin 5% EC (1:2.36), Flubendiamide 39.35% SC (1:1.81), and Neem oil 1500 ppm (1:1.74).
