Fall armyworm larvae were found dead in the chemical-sprayed plots, but they were absent in the grease-applied fields. A significant reduction in larval infestation was observed after 7-days of treatment applications. Emamectin benzoate sprayed at 0.4 g/liter of water and grease of about 0.15 g applied to the maize whorl or tip of a drooping leaf that touched the soil. The treatments were applied when the maize crop was at knee height and larvae damaged nearly 5–8% of the total plants. Standard agronomic package of practices followed for crop proper growth and development, and plant spacing maintained at 20 × 60 cm 2 with a plot size of 390 m 2. Smith) larvae load from a maize field in the winter seasons of 20 in Sarlahi, Nepal. An experiment was conducted to test the efficacy of grease and emamectin benzoate in a randomized complete block design with five replications to reduce fall armyworm, Spodoptera frugiperda (J.E.
