Cotton is an important fiber and cash crop throughout the world. Various factors influence the yield of cotton, with insect pests being of prime importance. Cotton bollworm cause serve damage to at boll formation stage. Management of the insect pests is mainly done through insecticides. The present research work was executed Ghurki Agricultural Farm House, District Kasur. The experiment was conducted using a Randomized Complete Block Design (RCBD). The experiment comprised of irrigation was done through drip irrigation and surface/flood irrigation arrangements. The spacing between plants was 30 cm, and between rows, it was 120 cm.Treatments and control were replicated in thrice. Synthetic insecticides; Emamectin-Benzoate,Profenophos+Cypermethrin, Lambda-cyhalothrin and Profenophos (Curacon) procured from Syngentacompany sale point located in Okara and were applied by Knapsack sprayer at recommended dose rates. Meaneffects were statistically significant regarding mean infested bolls per plant. In case of interaction effects,maximum mean infestation (2.73 infested bolls/plant) were recorded in control plot followed by Emamectin-Benzoate. (0.93 2.73 infested bolls/plant) while the lowest (0.53 infested bolls/plant) was recorded inProfenophos+Cypermethrin treated plots. Crop water productivity was higher (0.61 kg/m3) in experimentalplots under drip irrigation compared to those under surface irrigation (0.53 kg/m3).
