dc.description.abstractConsidering the demand to use ecofriendly products and finding out alternative to synthetic pesticides for management of sucking pests in chilli ecosystem, the experiment was conducted to evaluatebio efficacy of newly formulated botanical oil combinations from pongamia (Millettia pinnata), neem (Azadirachta indica), cotton (Gossypium spp.) seed and citronella (Cymbopogon nardus) oil against sucking pests of chilli in field condition during 2018-19. Investigation carried in laboratory for standardization of spreader (Detergent powder) concentration for various pongamia oil concentrations indicated that, 0.3 per cent spreader concentration was more efficient for stable emulsification of pongamia oil @ 2.5, 5.0 and 10 per cent concentration. Results from the investigation of phytotoxicity effects of pongamia oil on chilli plantsshowed that, pongamia oil @ 0.5, 1.0 and 2.5 per cent concentration were safer to chilli plants. Whereas, at double the dose of pongamia oil @ 5.0 and 10 per cent concentration recorded the moderate and high phytotoxicity on chilli plants. Hence, the lower dose of 2.0 per cent of botanical oil was selected as optimal dose for application in field for chilli pest management. Further, evaluation of bio efficacy of botanical oils and their combinations @ 2.0 per cent against sucking pests of chilli revealed that, combination of Pongamia oil+ Neem oil+ Cotton seed oil + Citronella oil @ (50:25:15:10 ratio) was superior in management of sucking pests followed by Pongamia oil+ Neem oil @ (50:50 ratio). Botanical oils and their combinations were found effective against sucking pests with no direct impact on honey bees and natural enemies. Significantly higher yield was obtained from plots treated with Pongamia oil+ Neem oil+ Cotton seed oil + Citronella oil @ (50:25:15:10 ratio) with 24.07 t/ha with a benefit cost ratio of 2.33 and can be recommended for management of sucking pests in chilli.
