Screening of the Best Insecticide in Reducing the Chickpea Pod Damage Inflicted by Gram Pod Borer, Helicoverpa armigera (Lepidoptera: Noctuidae) in Faisalabad

Muhammad Kashif Shahzad and Zahid Ali Shah    

Abstract: The present study was conducted to compare the effectiveness of different insecticides with reference to chickpea pod damage by the larvae of Helicoverpa armigera (Hubner) during Rabi season 2001-02. Four insecticides viz. cypermethrin (10 EC) @ 350 ml acre–1, endosulfan (35 EC) @ 1000 ml acre–1, lambdacyhalothrin (2.5 EC) @ 250 ml acre–1 and chlorpyrifos (40 EC) @ 800 ml acre–1 were tested twice. The screening of best insecticide was determined by comparing treated plots with untreated plots. Chlorpyrifos proved to be the best insecticide in reducing the pod damage and hence increased biomass and yield followed by endosulfan, lambdacyhalothrin, cypermethrin. However, all the insecticide treatments proved to be better in comparison with control in all the above mentioned aspects.
