Abstract:
Luxurious consumption of chemical and synthetic insecticides used for the management of noctuid pests like Spodoptera litura (Fab.) led to the development of resistance to a wide variety of insecticide classes. The present investigation employing cow-based organic products viz., Cow urine, Panchagavya, Darekastra, Agneystra, and Dashaparni were evaluated for their bio efficacy at different concentrations against S. litura under both laboratory and protected conditions. Maximum larval mortality of 76.67 percent was recorded by Darekastra (at 100%), followed by Darekastra (70.00% at 100.00% conc.) against 3^rd instar larvae. Cow-based organic products also caused significant reduction in larval population after sprayed with cent percent concentration under screen-house conditions. Under screen-house, Darekastra and Panchagavya recorded 59.00 and 54.00 percent population reduction, respectively after 3 days of spraying. The research clearly indicates that all the cow-based test products have significant larvicidal properties and could be used as an alternative to traditional pest management.
