Studies on the efficacy of four insecticides, viz., Endosulfan (0.05%), lambda cyhalotrin (0.004%), cypermethrin (0.01%) and mixture of Endosulfan + Btk (0.025%+0.05%) against Helicoverpa armigera (Hübner) revealed that cypermethrin was the most effective and gave maximum reduction of borer population (1.75 per three plants) followed by endosulfan, endosulfan + Btk and Lambda cyhalothrin.
