Abstract:
The field experiment was conducted to evaluate the efficacy of different treatments against Citrus blackfly (Aleurocanthus woglumi) and their impact on natural enemies at Sweet orange orchard of Nimkheda village district Aurangabad under the guidance of Research Guide, Department of Agricultural Entomology, College of Agriculture, Badnapur during Mrig bahar, 2020. The results indicated that the treatment of Flonicamid 50% WG was found to be most effective treatment in minimizing the blackfly population followed by Spinosad 45% SC and Spinetoram 11.7% SC. The treatments of Clothianidin 50% WDG, Imidacloprid 17.8% SL and Novaluron 10% EC found less effective. In case of natural enemies, all insecticides were found to be safe to relatively safe, with the exception of Novaluron 10% EC. The highest sweet orange yield (12.8 t/ ha) was obtained from trees treated with Flonicamid 50 WG @ 2.5 g/ 10 L. The maximum ICBR ratio was acquired from Clothianidin 50% WDG @ 0.8 g/10 L and recorded 1:27.61, while the lowest ICBR ratio was obtained from Novaluron 10% EC at 10 ml/10 L and recorded (1:2.20).
