The study was conducted to determine the efficacy of Botanical Insecticide Extract against Fruit and Shoot Borer (Leucinodes orbonalis G.) of Eggplant (Solanum melongena L.) under field conditions, specifically aimed to; (1) determined which of the different botanical plant extracts is the most effective in controlling EFSB of eggplant; (2) determined the effects of developed Botanical extract products, on the yield performance of eggplant (Solanum melongena L.), (3) determine which of the different botanical plant extracts is the most effective in controlling EFSB of eggplant and; (4) determined the phytochemical constituent of all the botanical extract used in the study. It was laid out in a Randomized Complete Block Design (RCBD) with 6 treatments replicated 4 times. Among the test plants evaluated, generally Hot chilli and Lantana was the most effective providing the highest reduction on EFSB followed by, Cubeba seriboa, Curcuma Longa respectively, however, it was revealed that all the tested samples shows par to the standard check. It also shown that all treatment significantly lowered on shoot and fruit infestation of EFSB as compared to untreated control check. The highest marketable fruit yield was obtained by Hot chilli, followed by Lantana camara, standard check, Curcuma Longa, and Cubeba seriboa as compared to untreated control check respectively. The percent gain over control was least with Curcuma Longa. From this study, it was concluded, and recommend that plant products are one of the most reliable/viable bio- rational options in pest management practices especially on the control of lepidopteran insect pest like the EFSB.
