Abstract: Objective To provide scientific data for deratization by comparing the control effect of coumatetraly,brodifacoum and sodium diphacinone in the laboratory and the field.Methods Selective feeding method in single cage was used to determine the palatability of the poison baits and the control effect in the laboratory.A hennery in dingbian county and two sanitariums in the suburbs of xi'an were selected as test fields and the powder trace method was used to determine the rodent density.Results The feeding indexes to coumatetraly,brodifacoum and sodium diphacinone were 0.61,0.24 and 0.51 respectively,which reached A,B and A grade respectively.The corrected mortality in the laboratory was 100%,reaching A grade.And that in the field were 91.34%,80.94% and 88.39% respectively,which also reached A,B and B grade respectively.Conclusion Three anticoagulants had good palatability and good control effect in the laboratory.Especially,the control effect of coumatetraly was the best among three anticoagulants.
