Abstract:
The field experiment for study the efficacy of different insecticides against American serpentine leaf miner, (Liriomyza trifolii) infesting watermelon, (Citrullus lanatus Thunb.) was carried out at Vegetable Improvement Scheme (VIS), Central experimental Station, Wakavali during summer 2021-22. From the investigation the efficacy of Chlorantraniliprole, Emamectin benzoate, Spirotetramat, Thiomethoxam, Pyriproxyfen, Azadirachtin and Beauveria bassiana was evaluated. The chemical insecticide Emamectin benzoate 5 SG recorded (9.28%) percent leaf infestation and was found most effective to control leaf miner also Chlorantraniliprole 18.5 SC (10.95%), Spirotetramat 150 OD (12.37%), Thiamethoxam 25 WG (12.62%) and Pyriproxyfen 10 EC (14.43%) found significant to control leaf miner. In the bio chemical treatments Azadirachtin (15.15%) gave better results than Beauveria bassiana (17.18%) and was less effective as compared to the chemical treatments. All the treatments were significantly better over control.
