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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
