Abstract
Pod damage assessment and pest status in both the field were determined. Rat population was estimated at pre- and post-rodenticide treatment within a grid system of 30 x 20 rows of coconut trees. Three rounds of baiting were undertaken with bromethalin and bromadiolone in fields A and B respectively. Equal number of trees were covered in the grid system. However The size of field B was larger than that of field A. Pod damage assessment and population estimate were higher in field B than field A. More bromethalin baits were applied in field A over bromadiolone baits in field B initially. Almost equal amounts of bromethalin and bromadiolone baits were applied in the baiting programme. A significant reduction in pod damage was brought about during the 2nd and 4th round of harvesting in field A by bromethalin while this was achieved in the third harvesting round in field B by bromadiolone. Although bromadiolone achieved a greater reduction in pod damage it had post-treatment pod damage levels equal to that of bromethalin. Post-rodenticide treatment population estimate indicated almost equal number of new and young rats present in the bromethalin and bromadiolone-treated fields respectively. Good bait acceptance and efficient rat control were observed after a duration of one month. Pod damage levels would be a better indicator for termination of a control programme rather than a predetermined level of bait replacement
