Abstract: Effectiveness of selected IPM modules was evaluated against H. armigera on tomato under field conditions at the farmer’s field at Binuria village near the Sriniketan of Birbhum District of West Bengal, for a year 2015-16 on tomato. The test variety was selected for the study was Patharkuchi, were transplanted in field in randomized complete block design. Nine modules with a non IPM module were evaluated over control and cost benefit ratio of these modules was also estimated. Seven modules were tested with integration of three control strategies i.e., use of Neem seed cake, Bird parching and use of Beauveria bassiana as biocontrol agent except in non IPM and control one. Seven modules included with pesticide of different mode of action, i.e. bio pesticides like B. bassiana, B. thuringiensis and HaNPV and chemical pesticide like Emmamectin benzoate, Spinosad, Flubendiamide, Rynaxypyr respectively. The Non IPM modules contains only chemical component, Cypermethrin. Results revealed that all IPM modules were effective than control in reducing fruit damage by H. armigera. However, maximum tomato yield (22.55 t ha-1) was obtained in M4 (use of Emmamectin benzoate was integrated with other control strategies) with highest incremental cost benefit ratio (2.35). It was concluded that integration of different control measures along with judicial use of pesticide in IPM program not only reduced fruit losses but also increased yield and net return.
