The efficacy of botanical insecticides i.e. Neem seed crude extract (2.5%), Turmeric (3.5%), Garlic extract (5%), Henge extract (2.5%) and Thiodan (0.07%) were evaluated against the insect pests (Earias insulana, Amrasca devastans and Oxycaremus loetus) of Okra at the New Developmental Farm (NDF) of the University of Agriculture Peshawar, Pakistan during 2012. Significant effect was recorded in all the treatments as compared to the control. The lowest mean number (2.0) of E. insulana larvae plant-1 were recorded in Neem and Thiodan whereas the highest mean number of 3.25 was recorded in control. Significant lowest mean number (2.00) of A. devastans was recorded in Thiodan and was highest (8.00) in control. O. leotus mean number were lowest (2.75) in Thiodan and highest (7.25) in control. It is also concluded that a highest yield (kg plot-1) were recorded in Thiodan and Neem. Results also showed highest percent increase in yield over control in Neem and Thiodan. Based on the total yield and percent yield increase Thiodan and Neem were the most promising insecticides for the effective management of insect Pest of Okra.
