Abstract

The efficacy of a novel bait formulation of coumatetralyl paste (Racumin Paste®) for the control of ricefield rats was evaluated in two farms in Laguna. Different treatment methods were evaluated by census of rat activity and tiller damage near harvest. Results indicate that the test formulation can be used either for surplus or unrestricted baiting or pulse or restricted baiting. It was found that coumatetralyl paste is palatable to rats and effective in reducing rat infestations in treated plots. The surplus baited plot exhibited the lowest mean percent damage (1.82%) compared to other treated plots and the control. The pulse baited plot also exhibited significant reduction of rat damage (3.7%), but was comparable to damage observed among the positive check plots. The positive check plots were treated by surplus baiting using coumatetralyl rice bait. The mean percent damage observed in the untreated plots. Monitoring for non-target species risk was carried out on all test plots. No dead non-target animals were found. Coumatetralyl paste was proved to be an efficient bait formulation in the control of ricefield rats, even when used in pulse baiting.
