Abstract

A field experiment was conducted to evaluate the efficacy of some insecticides viz., Emamectin benzoate 5% SG (11 ga.i./ha), imidacloprid 17.8% SL (22.5 g a.i/ha), Neem oil (3 ml/l), Beauveria bassiana (0.2 ml/l), fipronil 5% SC (50 g a.i/ha) against major pests of tomato (Lycopersicon esculentum Mill.). There were six treatments arranged in randomized block design with four replications. Fruit borer, whiteflies, aphids and leaf miner were found to be the major insect pests of tomato. Among the insecticide used, imidacloprid 17.8% SL was found to be the most effective for management of sucking pest viz., Whiteflies, Aphids, Thrips, Mealybugs, Jassids while emamectin benzoate was found more effective on tomato fruit borer. Beauveria bassiana was found least effective against all the insect pests.
