The current studies on incremental cost: benefit analysis of botanicals and insecticides were carried out at Students’ Instructional Farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (UP), India during Kharif 2022 and 2023 with nine treatments viz.,T1: Kaner powder 5 percent, T2: Garlic extract 5 percent, T3: Azadirectin 1500 ppm 5 ml/l, T4: Dasparni Ark 5 percent, T5: Flonicamid 50 WG 75 g a.i./ha, T6: Thiamethoxam 25 WG 50 g a.i./ha, T7: Imidacloprid 70 WG 50 g a.i./ha, T8: Dimethoate 30 EC 300 g a.i./ha and T9: Control (water spray). The economics of some newer insecticide molecules and botanicals against the white fly in mungbean was investigated, and when the data from both years of experiment were combined, it was concluded that Thiamethoxam 25 WG (50 g a.i./ha) (1:16.73) was the most effective insecticide among all the treatments, with maximum population reduction over control. Imidacloprid 70 WG (50 g a.i./ha) (1:10.27) was the second best treatment against white fly. Among the botanicals, Azadirectin 1500 ppm (5 ml/l) (1:6.21) was the most efficient against whitefly infestation in mungbean and could be utilized as an eco-friendly alternative to conventional pesticides for white fly management in mungbean.
