Abstract
Imidacloprid treated plots was most effective against Leucinodes orbonalis on brinjal. All the treatments were most effective after first spray where imidacloprid and dimethoate were highly effective in reduction of shoot infestation after second spray followed by other treatments. All the remaining insecticides found following order of preference in fruit damage reduction viz., imidacloprid> indoxacarb> dimethoate> spinosad> azadirachtin> Bt. The highest seed yield increase was obtained from imidacloprid treated plots and cost benefit ratio (1:63.15) was highest.
