Abstract: Field experiment was carried out during the rabi, 2018-19 to evaluate different modules for the management of Fall army worm in maize, which is a invasive pest of India during 2018. Four different modules were tested and data was recorded on per cent plant damage, per cent severity and percent reduction over control. Among different modules, Module IV recorded lowest per cent plant damage (3) and per cent severity (1.57) with 95.45 and 96.08 per cent reduction over control respectively after the imposition of treatments during rabi 2018-19. Module III is the next best module with 90.91 and 91.67 percent reduction over control of plant damage and severity. Regarding the grain yield, highest was recorded in module IV with 5480 kg/ha followed by module III with 5320 kg/ha. The highest cost benefit ratio was recorded in module I (1:.90) followed module III (1:1.61) and all tested modules were superior over control in controlling fall army worm damage in maize.
