Bio-efficacy of insecticides against Gram Pod Borer, Helicoverpa armigera (Hüb.) in Chick pea

The larval population of Helicoverpa armigera was regularly monitored and treatments were applied, as and when larval population reached Economic Threshold Level i.e. 03 larvae m⁻¹ linear row length. All the treatments were effective in controlling H. armigera. Indoxacarb 14.5 SC @ 60 g.a.i. ha⁻¹ was effective treatment for Helicoverpa management as this resulted higher grain yield and more return based on B: C ratio. HaNPV @ 400 LE was least effective treatment compared to other new insecticide molecules, but it was on par with a conventional insecticide, endosulfan 35 EC @ 350 g.a.i. ha⁻¹ at all stages of management.
