Smith), is a voracious agricultural pest of global economic importance 1. The fall armyworm, Spodoptera frugiperda (J.E. Thus, an eco-friendly material like grease can be used as an agroecological method for managing fall armyworm larvae among small-scale land-holding maize farmers. The armyworm larvae might get irritated, feel insecure, and move far away from the test plots searching for food materials. No crop damage was observed among the grease-treated plants, which might be due to restrictions in the movement of larvae on the maize crop. 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.
