Field studies on efficacy of novel insecticides against Helicoverpa armigera (Hubner) infesting on Chickpea

Yogeeswarudu, B and Venkata Krishna, K

Field trials were conducted in randomized block design with three replications of seven treatments during Rabi season 2012-13. Efficacy of different treatments viz., indoxacarb 14.5 SC @ 0.5 ml/l, profenofos 50 EC @ 2.0 ml/l, imidacloprid 17.8 SL @ 1 m/l, novaluron 10 EC @ 1.5 ml/l, fipronil 5 SC @ 2.0 ml/l and lambda cyhalothrin 5 EC @ 1 ml/l was tested against Helicoverpa armigera larvae. The results revealed that indoxacarb 14.5 SC @ 0.5 ml/l was found best with minimum population of H. armigera at first spray indoxacarb 14.5 SC @ 0.5 ml/l was found best among all the treatments with the minimum larval population at first spray first spray of 1.53, 0.46, 0.73 larvae/five plants being 89.45, 97.01, 95.83 percent reduction over control at 3 DAS, 5 DAS & 7 DAS respectively. The minimum larval population at second spray of 0.00, 0.26 and 0.00 larvae/five plants by giving 100, 98.74 & 100 percent reduction over control, at 3 DAS, 5 DAS & 7 DAS respectively.
