Abstract:
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 cow-based organic products, cow urine, Panchagavya, Darekastra, Agneystra, and Dashaparni were critically evaluated for their repellent activity at the different concentrations against 3^rd instar larvae of S. litura under laboratory conditions. The maximum repellency of 80.00 percent was recorded by Darekastra, followed by Panchagavya with 76.67 percent antifeedant activity (both at 100.00%). The study clearly indicates that all the cow-based test products have significant repellent properties and could be potentially used for the deterrence of peak pest activity.
