An experiment was conducted to study comparative efficacy of selected chemicals, botanical and biopesticides against fall armyworm in Maize. The trial was designed and evaluated in different locations Rahuri, Jhansi, Ludhiana, Dharwad & Bhubaneshwar under All India Co-ordinated Research Project on forage crops & Utilization in India. The results of field experiment concluded that, among the different treatments the lowest population of S. frugiperda were recorded in the treatment of emamectin benzoate 5 SG @ 5 ml/10 lit of water (16.53 % infestation of plants) which was significantly superior over rest of the treatments. Next best treatment recorded was chlorpyriphos 20 EC (26.36%) @ 20 ml/10 lit of water. The treatment Metarhizium (Nomuraea) rileyi 1.15% (30.73%) WP@ 75 g/10 lit of water followed by Metarhizium anisopliae 1.15% WP @ 75 g/ 10 lit of water (31.30%), Beauveria bassiana 1.15% WP (32.13%) @ 75 g/10 lit of water, Beauveria bassiana 1.15% WP (32.96%) and Metarhizium (Nomuraea) rileyi 1.15% WP (35.10%) in treated plots, respectively.

On the basis of results of current investigation, it can be concluded that for management of fall armyworm, S. frugiperda the treatment of emamectin benzoate 5 SG @ 5 ml/10 lit of water shown most effective in reducing plant damage by fall armyworm as well as highest return on investment per rupee.
