Experiments were carried out at ten locations of Saran district, Bihar during kharif season 2017 with okra crop cv ‘Supper green’. The assessment reveled that module (M4) proved the most effective treatment against okra pest and diseases i.e. shoot and fruit borer, Earias vittella F., yellow vein mosaic virus, Bemisia tabaci (Genn.) and red spider mites, Tetranychus urticae Koch in which lowest incidence was recorded as compared to other IPM modules, farmer practices and control plot during 2017. IPM Module III (shoot and fruit borer 7.02% on shoot, 9.87% on fruits, yellow vein mosaic virus 16.25% and red spider mites 3.35% infestation) was next effective against the major pest of okra crop in compression to IPM modules I (shoot and fruit borer 12.24% on shoot, 18.12% on fruits, yellow vein mosaic virus 24.42% and red spider mites 9.05% infestation), respectively. Significantly, maximum fruit yield was observed in module IV 210.10 q/ha. This was significantly superior over all other module. The impact of various IPM modules showed that net return was also higher in module IV which was Rs.76430.00/ha.
