Abstract:
Field experiments were carried out on the impact of different BIPM modules on the incidence insect pests, natural enemies and pollinators. Pooled data for three years revealed that, among the modules, Module-III comprising of seed treatment with imidacloprid (5 g/kg) + metalaxyl (5g/kg) + handpicking and destruction of early instatrs of S. litura and S. obliqua + two sprays with spinosed 45SC @ 0.0045%, was significantly superior over others in reducing the pest population and in recording higher number of natural enemies. The next best module was module-IV. Module-III recorded highest yield of 1233.79 Kg/ha followed by Module-IV which recorded yield of 1100.42 Kg/ha. The module III recorded a highest benefit cost ratio of 2.91 followed by module-IV which recorded a B:C ratio of 2.63. Incremental Benefit: Cost Ratio (IBCR) was maximum in module III (1.33) followed by module IV (1.05), module II (0.80) and module I (0.65).
