Abstract: The field experiment was carried out to evaluate the different whorl applications for management of fall armyworm, Spodoptera frugiperda (J. E. smith) on maize. An experiment with nine whorl applications viz., Carbofuran 3G @ 33 Kg / ha, Ash @ 35 kg/ha, Sand + Lime (9:1) @ 62 kg/ha, Entomopathogenic nematode @ 5 Kg / ha, Poison bait (Wheat bran 10 Kg + Jaggary 2 Kg + 3 lit. Water + Thiodicarb 100 g) @ 44 kg/ha, Beauveria bassiana @ 2.5 kg/ha, Metarhizium anisopliae @ 2.5 kg/ha, Nomuraea rileyi @ 2.5 kg/ha was laid out in randomized block design with three replications along with an untreated control for comparison. Among the different management option evaluated Nomuraea rileyi was superior in managing the population of fall armyworm and safer to natural enemies i.e. lady beetle, predatory bug and earwig. It was followed by Metarhizium anisopliae, Beauveria bassiana, poiaon bait and sand + lime. The least efficient treatment with highest population among all whorl application was ash. Highly toxic whorl application to natural enemies was carbofuran and poison bait.
