Impact of integration of Bamboo traps with rodenticides on rodent control in Rice

Combined effect of rodenticides and traps were evaluated at different growth stages of rice against field rodents in terms of live burrow count (LBC/ha), trap index (TI) as well as % cut tillers in both boro and sali rice, respectively. Among different treatments, bromadiolone (0.005%) at panicle initiation stage and bamboo traps at milky stage was found effective in reduction of live burrow (77.4 & 80.2%), trap index (65.8 & 70.6%) and cut tillers (63.0 & 67.2%) in boro and sali rice, respectively. This was followed by bamboo traps at maximum tillering stage and bromadiolone (0.005%) at panicle initiation stage which recorded (70.6 & 71.8%) reduction of live burrow, (60.9 & 67.0%) reduction in trap index and (56.2 & 63.4%) reduction in cut tillers in both boro and sali rice, respectively. Baiting with Zinc phosphide (2.0%) at panicle initiation stage followed by bamboo traps at milky stage reduced LBC/ha and trap index to 67.4 and 52.1%, respectively in boro rice. Whereas, in sali rice, the reduction percentage in respect of LBC/ha and trap index was 64.2 and 60.9%, respectively.
