To evaluate the comparative efficacy of synthetic insecticide and botanical extracts against the fruit and shoot borer of brinjal under field condition a study was carried outatAgricultural Research Institute, Tarnab during 2021. Experiment was laid out in Randomized Complete Block Design (RCBD) comprising of six treatments. Treatments includedparthenium leaf extract, neem seed extract, neem oil,tobacco leaf extract and flubendiamide. Results revealed that in shoot infestation, lowest percent shoot infestation after 1^st, 2^nd and 3^rd spray was observed in plots treated with flubendiamide (10.22, 4.33 and 1.22) followed by neem oil (12.22, 7.55 and 5.22), neem seed extract (13.00, 8.88 and 6.66), tobacco leaf extract (13.66, 10.22 and 8.33) and parthenium leaf extract (15.77, 13.88 and 12.22) was recorded least effective against the Brinjal fruit and shoot borer. Similarly in fruit infestation, lowest percent fruit infestation after 1^st, 2^nd and 3^rd spray was observed in plots treated with flubendiamide (6.10, 3.66 and 0.66) followed by neem oil (8.0, 6.44 and 5.33), need seed extract (9.00, 7.99 and 6.44), tobacco leaf extract (10.10, 8.99 and 7.77) and parthenium leaf extract (10.66, 9.66 and 8.66) respectively. Among the entire tested treatments flubendiamide treated plot showed highest marketable yield 11010 kg/ha while the lowest yield was recorded in untreated plot 3717 kg/ha.Flubendiamide showed highest Cost Benefit Ratio (1:40.51) while lowest was recorded by tobacco leaf extract (1:10.33).The results concluded that neem oil and neem seed extract are the best possible alternativeof synthetic pesticides flubendiamide and are recommended to be included in IPM programs against brinjal shoot and fruit borer.
