The tomato pinworm is the most serious threat to tomato production systems world wide. The investigation was carried out inside a naturally ventilated polyhouse condition to understand bioefficacy of phytochemicals and bioagents for the management of Tuta absoluta. The treatments comprised of chlorantraniliprole 18.5 SC @ 30 g a.i/ha, emamectin benzoate 5 SG @ 10 g a.i/ha, garlic extract @ 5 ml/litre of water, spinosad 45 SC @ 83 g a.i/ha, indoxacarb 14.5 SC @ 60 g a.i./ha, azadirachtin 5% @ 200 ml/ha, Beauvaria bassiana 2.25% WP 2 kg/ha and untreated control, were investigated for their efficacy against Tutta absoluta. Chlorantraniliprole 18.5 SC @ 30 g a.i./ha was found superior in control of Tuta absoluta whereas in organic tomato production, garlic extract @ 5 ml/litre stands first in control T. absoluta. Emamectin benzoate 5 SG @ 10 g a.i./ha was also found effective in lowering overall population of T. absoluta in tomato.
