There were eight treatments including control. The highest % reduction control of aphids after 3rd spray was 91.2 recorded for T6 treatment and T5 was the next superior treatment having a % reduction of 86.2. The highest percent reduction in pod damage (75.5%) was recorded for T6 after 3rd spray, while T5 was the next superior treatment and the pod borer damage was noted to be 72.2%. T5 yielded the highest mean produce of Okra per plant and was recorded to be 446.3 g. These findings revealed that bio-insecticide can be effectively used to control aphid population as well as the fruit infestation of Okra and improving the yield of Okra. The bio-insecticides can also lower the inputs of residues in the crops and pose least toxicity to non-targeted organism and also readily degradable.</p> <p> </p> <p> </p> <p><em> </em></p>}, number={3}, journal={Biological Sciences - PJSIR}, author={Ahmad, Taimur and Khan, Rasool and Khattak, Tariq Nawaz and Ullah, Ihsan and Khan, Ayaz and Khan, Saleem}, year={2020}, month={Nov.}, pages={207–213} }
