The study was conducted to check the efficacy of synthetic insecticides against tobacco aphids in District Mardan during spring 2023. The tobacco genotype Speight G28 was grown and standard agronomic practices were followed. Experiment was laid out in Randomized Complete Block Design (RCBD) with four treatments via Confidar, Actara, Furadon and Control, replicated 3 times. Results revealed that all the tested insecticides performed better then control in managing aphids infestation. However, Confidor resulted in better control of aphids (2.31 plant-1), higher plant height (83.67 cm), number of leaves plant-1 (27.53), leaf area (69.60 cm2), grade index (2.30%), yield (1506.70 kg ha-1) as well as nicotine (3.50%) and total sugar contents (6.73%). It is concluded that performance of Confidar is superior with respect to low aphid infestation. Therefore, tobacco genotype Speight G28 should be cultivated along with judicial use of Confidor for better management of aphids infestation and getting higher tobacco yield.
