Abstract


Field experiments were conducted to evaluate the nine different Integrated Pest Management (IPM) modules including standard check and control against South American tomato moth, Tuta absoluta on cv. ‘NS-501’ of tomato. Module 7 (Pheromone traps @20/ha, Metarhizium anisopliae @3ml/L, Spinosad (45% SC) @0.2ml/L and Azadirachtin (1% EC) @ 2ml/L) followed standard check (Indoxacarb (14.5SC)@0.75ml/L, Flubendiamide (480SC) @0.2ml/L, Cyantraniliprole (10.26 OD)@0.3ml/L, Spinetoram (11.7 SC)@0.75ml/L) and Module 6 (Pheromone traps @20/ha, M. anisopliae @3ml/L, Azadirachtin (1% EC) @ 2ml/L and Spinosad (45% SC) @0.2ml/L) were found effective in reducing T. absoluta population. The highest yield (59.31 t) was obtained from Module 7 compared to farmer’s practice i.e., standard check (52.92 t) and control (20.61 t). Highest Cost-Benefit ratio were obtained from Module 7 (1:3.25) compared to standard check (1:2.72) and control (1:1.47).
