Bio-efficacy of various insecticides against insect pests of cucumber (Cucumis sativus L.) under protected cultivation

Abstract

An experiment was conducted in polyhouse to evaluate insecticide for controlling leaf miner, whitefly and thrips infesting cucumber crop with the treatments i.e., difenthiuron 30 WP, acephate 75 SP, Acetamiprid 20 SP, spiromesifen 22.9 SC, Beauveria bassiana and neem oil (1%) including untreated control at High-tech Unit of Department of horticulture, Rajasthan College of Agriculture, MPUAT, Udaipur during kharif season, 2017, subsequently. All among the treatments, acetamiprid 20 SP found most effective against whitefly as recorded 62.79 per cent population reduction. While in case of leaf miner maximum reduction of maggot population was observed in difenthiuron 30 WP was 73.52% and in thrips highest population reduction observed in the treatment acetamiprid 20 SP recorded 55.74 per cent reductions in polyhouse cucumber crop.
