Abstract: The comparison of the effect were carried out in the laboratoty and the field by 0.005%, 0.01%, 0.02%, 0.05% of Natrium Diphacin bait against rodents. Same effect was obtained using 4 concentrations in the laboratory; the best concentration was 0.02% in the housing field; the effct being same at 0.01%, 0.02%, 0.05% and being poorly at 0.005% were found in the rice field. Experiment showed that lower concentration was more palatable than higher, but the time of the mortal animal was delay in lower concentrations. The results obtained are compared with data previously obtained for various concentration Natrium Diphacin against rodents. It suggests that 0.02%, would be suitable in the housing by the saturation and in the rice by the weekly interval
