Field efficacy of different insecticides against aphids (Aphis gossypii Glover) in chilli

Abstract

Field studies were carried out during Rabi season of 2016-17 and 2017-18 at the Central Horticultural Research Station, Odisha University of Agriculture and Technology, Bhubaneswar in randomized block design with six insecticidal treatments which were replicated four times and tested against aphids in chilli variety “Utkal Ava”. Among them, sequential spraying of acephate 75 SP @ 1.5 g/l + neem oil @ 2.0 ml/l, fipronil 5 SC @ 1.0 ml/l + neem oil @ 2.0 ml/l, imidacloprid 70 WG @ 2 g/15 l + neem oil @ 2.0 ml/l and cyazypyr 10.26 OD @ 1.8ml/l proved to be superior than other treatments in effective management of aphids infesting chilli. Further, cyazypyr 10.26 OD @ 1.8 ml/l was found to be the least effective treatment against this pest.
