Abstract: Objective To understand the deratization effect and toxicity of 0.0375% racumin wheat bait to non-target animals in laboratory and different fields,and provide scientific basis for rodent control.Methods Detecting the palatableness and effect of poison bait on deratization in laboratory by the methods of grouping rising and providing poison bait selectively,and determine the rat density with 100 standards powderboards method and calculate the deratization rate,toxicity of poison bait to rabbit and chicken by the methods of single rising and providing poison bait non-selectively and detect indirect toxicity of poison bait by feeding cats and dogs with poison bait.Results The coefficient of intake was 0.73,the deratization rate was 100% in laboratory;It was 97.61%,97.43%,97.71%,100% and 100% respectively in natural countryside,canteen,hotel,food supermarket and food processing factory.The total field deratization rate was 98.02%,the corrected total field deratization rate was 98.17%;when continuously providing poison bait 3 d,the mortality rate of rabbit and chicken was 40% and 20% respectively,while continuously providing 5 d,the mortality rate was 100% and 80% respectively.When feeding cat continuously 3 d with poisoned mouse and domestic dog continuously 2 d with poisoned brown rat,no poisoning occurred.Conclusion The palatableness of the product is good,the deratization effect are good in laboratory and different fields,it has toxicity to the non-targetanimal,but the effect is limited,so it is a good and relatively safe rodenticide.
