Bio-efficacy of insecticides against Gram Pod Borer, Helicoverpa armigera (Hüb.) in Chick pea
2014
Singh, Amar | Ali, S. | Gupta, P.K.
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
