The study evaluated the efficacy of various oils and combinations against sucking pests of chilli. The concentration of emulsifier for efficient emulsification of oils was also studied. Detergent powder @ 0.3% effectively emulsified pongamia oil @ 2.5, 5.0 and 10%. Combination of pongamia oil + neem oil + cotton seed oil + citronella oil (50:25:15:10 ratio) @ 2.0% was superior in management of sucking pests followed by pongamia oil + neem oil (50:50 ratio) @ 2.0%. Botanical oils and their combinations had no direct impact on pollinators and natural enemies except citronella oil. Pongamia oil + neem oil + cotton seed oil + citronella oil (50:25:15:10 ratio) and pongamia oil + neem oil (50:50 ratio) yielded significantly higher yield over other treatments.
