Bioefficacy of insecticides against onion thrips (Thrips tabaci Lindeman)

Abstract

Field experiments were undertaken at the Department of Agril. Entomology, Post Graduate Institute, MPKV, Rahuri, India to study bioefficacy of Basil oil (Ocimum tenuiflomm syn. O. sanctum) (0.2%), geranium oil (0.2%) along with commonly used synthetic insecticides viz., fipronil 5 SC (0.005%) profenophos 50 EC (0.05%), acephate 75 SP @ (0.075%), N.S.E (4%) and dimethoate @ (0.06%) against onion thrips, Thrips tabaci Lind, during 2013-14 and 2014-15. The data revealed that fipronil 0.005 per cent excelled over all other treatments and was effective in controlling thrips population.
