Injudicious application of synthetic pesticides for the management of lepidopteran pests like Spodoptera litura (Fab.) led to the development of physiological resistance to several classes of insecticides, predominantly against organophosphates and carbamates. In the present study, five woe-based organic products, cow urine, Panchagavya, Darekastra, Agneystra, and Dashaparni were critically evaluated for their antifeedant activity at the different concentrations against 3^rd instar larvae of S. litura under laboratory conditions. The maximum antifeedant activity of 60.68 percent was recorded by Darekastra, followed by Panchagavya with 51.67 percent antifeedant activity (both at 100.00%). The study clearly indicates that all the cow-based test products have variable antifeedant or feeding deterrent properties and could be potentially used for the deterrence of peak pest activity.
