Field efficacy of six botanicals in the management of major pests viz., spotted leaf beetle Epilachna vigintioctopunctata and shoot and fruit borer Leucinodes orbonalis of brinjal was evaluated in combination with vermicompost, farmyard manure and straight fertilizers as main treatments and six botanicals as sub treatments employing the split plot design. Organic manures proved to be superior when compared to the fertilizers as regards pest incidence. Vermicompost was significantly more effective as regards fruit borer infestation. NSKE 5% extract proved to be the most effective against fruit borer. Neemgold (Azadirachtin) 5ml/l, Pongamia glabra 5% leaf extract and Annona squamosa 5% leaf extract also were effective in reducing the fruit borer incidence. Murraya koenigi 5% extract and chilli-garlic 5% extract were less effective. Significantly highest marketable yield was obtained in Neemgold (Azadirachtin) 5ml/l followed by NSKE 5%.
