With fall armyworms at unprecedented levels in Nebraska this season, many growers have questions about how to manage this pest. Fall armyworm (Spodoptera frugiperda) is a migratory pest that does not overwinter in our region; moths move north from the southern U.S. each summer and can build quickly in late summer and early fall. In alfalfa, forage, and hay systems, risk is highest in new seedings and tender post-cut regrowth, and infestations often expand from field edges or adjacent small grains and pastures.
