Abstract

                                The survey was conducted to assess the pesticide use patterntomato and two field experiments were conducted to assess theefficacy of new insecticide molecules against tomato fruit borer. Theresults revealed that farmers used eighteen different insecticidesfor the management of fruit borer in tomato and quinalphos,chlorantraniliprole, flubendamide, chlorpyriphos, lambda cyhalothrinand indoxacarb were found to be frequent used insecticide in tomato.Among the insecticides tested, flubendiamide 480 SC registeredpercent damage reduction of about 86.37 and 96.41 per cent ¢ percent and 99.6 per cent reduction of larval population overuntreated control in first and second experiment, respectively followedby chlorantraniliprole 18.5 SC at 30 g a.i.ha-1, lambda cyhalothrin 5EC @ 15 g a.i. ha-1, indoxacarb 14.5 SC at 75 g a.i. ha-1, chlorpyriphos20 EC at 200 g a.i. ha-1 and quinolphos 25 EC at 250 g a.i. ha-1. Theharvest time residues of flubendiamide 480 SC at 48 g a.i. ha-1 wereat a below detectable levels in tomato fruit and soil samples collectedduring the first harvest. Hence, flubendiamide 480 SC @ 48 g.ai. ha-1 isincluded as a best fit component in the integrated pest managementof fruit borers in tomato.
