Areawide Ricefield Rat Control by Small Scale Landowners in S.E. Asia through the Co-ordinated Application of Flocoumafen Block Bait

  • N. M. Pearman

Abstract

Two large (approx. 200ha) trial sites of small holder ricefields were selected in Indramayu Regency, West Jara province, Indonesia. Flocoumafen 3.5g wax block baits were applied to one site as three area-wide pulses of 100 blocks/ha followed up by two selective spot treatments to marginal areas of particularly high infestation. Rodent control in the second area was by traditional farmer practice including hunting or chasing, fumigation and the use of acute poisons such as zinc phosphide and aldicarb. The co-ordinated applications of flocoumafen blockbait resulted in a reduction of damaged seedlings which failed to mature or yield from 28% (control) down to 0.4%, and an increase in yield from 2.5 MT (control) to 7.3 MT dry unhulled rice per ha. Similar trials in Laguna province, Philippines also gave excellent rodent control resulting in significant decreases in crop damage (% cut tillers) with no observable effects on domestic or wild non-target species.
