Abstract
The indiscriminate use of pesticides has resulted into various consequences most importantly the destruction of natural enemies. So prior to inclusion of any insecticide in pest management programme, its insecticidal properties, mammalian toxicity and safety to natural enemies must be evaluated. In this context, a study was conducted in Hisar (Haryana) to assess the relative safety of newer insecticides to natural enemies when used against okra shoot and fruit borers during kharif 2019 and 2020. Experiment was laid out in randomized block design in plot size of 5 ï‚´ 4 m with three replications for each treatment. Insecticides viz. chlorantaniliprole 18.5 SC, emamectin benzoate 5 SG, Pyridalyl 10 EC, lambda-cyhalothrin 5 EC, cypermethrin 25 EC quinalphos 25 EC were applied thrice at 25, 6.75, 15, 50, 37 and 200 g a.i. per ha, respectively. Results revealed that among various insecticides, application of chlorantaniliprole 18.5 SC and emamectin benzoate 5 SG did not cause any significan
