Field trials were conducted during the year 2016 at Research Farm of Department of Seed Science and Technology, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was carried out on okra cv. P-8, sown at three sowing dates viz., 1st June, 15th June, 30thJune, 2016 under six IPM modules and untreated control. The results showed that sowing–I recorded the minimum insect pest population (7.94 jassids/plant and 1.17 blister beetles/plant). IPM module-I (Seed treatment with imidacloprid @ 3 ml/kg, foliar spray of imidacloprid @ 0.3 ml/lt at 40 days after sowing (DAS), foliar spray of spinosad @ 0.3 ml/lt at 50 DAS, emamectin benzoate @ 0.4 g/lt at 70 days, foliar spray of spinosad @ 0.3 ml/lt at 80 DAS) provided maximum protection against insect-pests (4.13 jassids/plant and 0.24 blister beetles/plant) while maximum population was in control (5.71 jassids/plant and 0.54 blister beetles/plant).
