Shoot and fruit borer (Leucinodes orbonalis G.) is one of the most destructive pests in brinjal in South Asia. Studies on effectiveness of different chemical insecticides against shoot and fruit borer causes 20 – 60% yield reduction was evaluated under field condition at Agricultural College and Research Institute, Killikulam, Thoothakudi during kharif from July 2018 to October 2018. Shoot and fruit infestation were minimum in Spinosad 45 SC treated plots with the per cent of in shoots and in fruits when compared to the untreated check (). Next to this, Emamectin benzoate 5 WG and Novaluron 10 EC performed better with the shoot and fruit infestation viz., to in shoot and to in fruits respectively. The average yield recorded was ranging from t/ha to t/ha in pesticide treated plots when compared to the untreated check ( t/ha). The highest yield of was recorded in Spinosad 45 SC treated plots followed by Emamaectin benzoate5 WG ( t/ha) and Novaluron 10 EC ( t/ha). | Evaluation of biorational pesticides for management of shoot and fruit borer (Leucinodes orbonalis G.) in Brinjal
