Evaluation of Novel Molecules against Fall Armyworm (Spodoptera frugiperda) Infesting Maize

Maize (Zea mays L.) is one of the most important cereal crops grown worldwide and has better adaptability to diverse environmental conditions. An experiment was designed to evaluate the combi as well as sole formulations of some commonly used insecticides such as chlorantraniliprole 9.3% + lambda cyhalothrin 4.6% ZC, novaluron 5.25% + emamectin benzoate 0.9% SC, emamectin benzoate 5% SG, spinetoram 11.7% SC, flubendamide 480 SC, spinosad 45% SC against fall armyworm during the rabi season of two consecutive years (2021-22 and 2022-23) in Bihar. It was observed that plant infestation as well as cob infestation was significantly lower in plots where crops were sprayed with combi-formulation ie chlorantraniliprole + lambda cyhalothrin @ 23.0 + 11.5 g ai ha^-1and novaluron + emamectin benzoate @ 52.5 + 9.0 g ai ha^-1 as compared to plots where crops were sprayed with sole formulations of insecticides. As per the intensity of damage and yield, no significant difference was observed among the plots treated with either combi or sole formulations.
