abstract
The field experiment was conducted to assess the bioefficacy of various insecticides against Helicoverpa armigera on pigeon pea (Cajanas cajan (L) Millsp.) with eight treatments including an untreated control. In treatments viz., Quinalphos 25 EC, Emamectin benzoate 5 SG, Indoxacarb 14.5 SC, Chlorantraniliprole 18.5 SC, Chlorpyriphos 20 EC, Flubendamide 39.35 SC, Lambda cyhalothrin 5 EC. These treatments replicated thrice in randomized block design. The performance of each insecticide treatment was judged on the basis of larval incidence, pod damage, grain damage and grain yield. Considering the effectiveness of various insecticides in reducing the larval population, the treatment with chlorantraniliprole 18.5 SC was emerged as the most promising treatment for the management of Helicoverpa armigera (Hubner). The next promising treatment reducing H. armigera larval population was flubendiamide 39.35 SC which was followed by the treatment with indoxacarb 14.5 SC. The treatment with chlorantrniliprole 18.5 SC was superior in reducing collective pod and grain damage. The maximum grain yield was obtained from the plots treated with chlorantrniliprole 18.5 SC (17.18 q /ha).
