Abstract
Spodoptera frugiperda (J E Smith) is an important pest of sorghum, which is causing heavy losses in Ethiopia. This study was conducted at the Metema experimental site Gondar, Ethiopia during main cropping seasons of 2020 and 2021 to determining appropriate rate of selected insecticides against S. frugiperda larvae using randomized complete block design with three replications. Melkam variety used at a seed rate of 15 kg ha-1 and plot size of 22.5 m2 was used. Plots sprayed with Proven and Agrolambacin in company recommendation rate reduced the incidence of larvae and gave higher grain yield. Cost benefit analysis showed that maximum net benefit (ETB 63,410.3 ha-1) was obtained with followed by Agrolambacin 55535 ETB ha-1.
