Abstract

Field investigation was conducted to evaluate the efficacy of some biopesticides against shoot and fruit borer (Leucinodes orbonalis Guen.) on brinjal during Rabi season in 2015-2016. Among the treatments, Azadirachtin 1% EC @ 2ml/L was found superior than other treatments with 10.92% mean shoot infestation and 10.04% mean fruit infestation, respectively followed by Karanjin 2% EC @ 2ml/L (13.42% shoot and 12.83% fruit infestation). Azadirachtin 1% EC @ 2ml/L also registered as highest marketable fruit yield (38.75 q/ha). It can be concluded that Azadirachtin could be proved effective in the management of brinjal shoot and fruit borer under organic farming and IPM programmes.
