Said Mir Khan and Zahid Ullah

Azodrin, Deltanete, Methaphos, Ripcord and Thiodan were sprayed with an interval of fifteen days.The results revealed that all the insecticides significantly reduced the bollworms infestation. Ripcord was found significantly more effective in reducing the infestation of bollworms followed by Methaphos, Deltanete, Azodrin and Thiodan. High doses of all insecticides gave better control of the pests than medium and low doses. However, all the tested insecticides at all the three doses were found significantly better than control.
