Four single-dose and four anticoagulant rodenticides were tested in the laboratory against two species of field rats. Arvicanthis abyssinicus and A. dembeensis. Chlorophacince bait with 25 ppm. A.i. proved the best anticoagulant poison and 4% zine phosphide bait the best single-dose poison. At present, in Ethiopia, there are seven different rodenticides available commercially of from Government organizations. None of them is completely satisfactory for field use by peasant farmers. Three (sodium fluoroaccetate, zinc phosphide and thallium sulphate) have very high toxicity to main and domestic animals. One (red squill is extremely expensive and gives inconsistent results. The other three (coumatgeralyl, warfarin and chlorophacinone) are slow-acting, anticoagulant, multi-dose rodenticides whose use is difficult to explain to a peasant farmer. Nevertheless, it is essential to make at lest interim recommendations for the use of rodenticides in the filed. It is also essential to test the performance of these toxicant against the actural rat species which are common on farmers' fields in Ethiopia. It was therefore, decided to do some laboratory test with all seven plus diffenacoum in order to measure the toxicity and acceptability by two species of rodents and hazards to cats so that the best possible advice on their use could be given to farmers and extension agents.
