ABSTRACT
The bouquet bioassay experiments under laboratory condition revealed that the corrected percentage mortality of Helicoverpa armigera was 76.9-80.0% at recommended dose of spinosad. Good biological efficacy of this new molecule was also reflected in the suppression of larval population and reduction of damage to bolls, squares, locules and kapas in the field.
