The experiment was carried out in farmers’ fields of Chaklarhat, Tunirhat, Panchagarh and Research Field of Horticulture Research Center, Bari, Gazipur from October 2017 to June 2018 to findan effective and suitable management approach against tomato leaf miner, Tuta absoluta. There was a total of ten treatments, viz., Treatment 1 = Application of Metarrhizium anisolpiae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water, Treatment 2 = Foliar spray of azadirachtin (Bio-Neem plus 1EC @ 1ml/L of water), Treatment 3 = Foliar spray of Bacillus thuringiensis (Biocure) @ 2g/L of water, Treatment 4 = Mass trapping through installation of delta sex pheromone trap, Treatment 5 = Spraying of spinosad (Tracer 45WSC) @ 0.5ml/L of water, Treatment 6 = Spraying with chlorantraniprole (Coragen 20SC) @ 0.5ml/L of water, Treatment 7 = Hand picking and destruction of infested leaf and fruit, Treatment 8 = Foliar spray of B. thuringiensis (Biocure) @ 2g/L of water + mass trapping through installation of delta sex pheromone trap + application of M. anisolpiae biopesticide in soil @ 5g/L of water, Treatment 9 = Foliar spray of azadirachtin (Bio-Neem plus 1EC @ 1ml/L of water) + mass trapping through installation of delta sex pheromone trap + Application of M. anisopliae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water and Treatment 10 = untreated control were evaluated against T. absoluta following RCB design with three replications. Results revealed that foliar spray of azadirachtin (Bio- Neem plus 1EC @ 1ml/L of water) + mass trapping through installation of delta sex pheromone trap + application of M. anisopliae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water performed best in reducing T. absoluta infestation, increase of marketable yield and highest marginal benefit cost ratio.Keywords
