Integrated rice rat management.
1987
Buckle A.P.
Recent work in several Southeast Asian countries has been aimed at the development of rice rat control schemes based on IPM [Integrated Pest Management]. Crop loss surveys have highlighted the extremely widespread nature of the problem and demonstrated that existing surveillance methods tend greatly to underestimate its importance. Field trials have shown that rice rat control using the potent second generation anticoagulant brodifacoum is a very cheap agronomic input, a yield increase of only 1-2% usually repaying the cost of treatment. Simple, farmer-applied surveillance schemes have been developed which provide extension workers with the information needed to determine when and where to organize rodenticide applications. The paper described these developmental studies and the large-scale verification of the overall strategy at a number of sites in Indonesia.
