Abstract: The Shashuxing by lianing chemical industry Research Instituse in 1992, It is Indandione anticoagulaunt rodenticide. This paper repodts the results of the toxicity defermination and palatability obser Vation and efficency elimination of Shashuxing for the Meriones ungiculatus.The values of acute(single close)oral toxicity LD₅₀ is 2.8255±1.7674mg/kg.SE₅₀ is 0.1390,The lincar regression equation is Y=3.4317±3.4766x. The poisoning bait of Shashuxing is of good accepfance,The coefficient of taken wheat bait at concentration of 0.005% of pesticide agent for M. ung.is 1.3330.In field test,0.0025 0.005 0.01% of taken wheat baits 2 gram per borrow putting the killing rate was 97.98%. 100% 100%respecfively.affer eleven days calclated the rate of distincf borrow. The results confirmee that Sha shuxing possessed Very stronger toxicity and death period is mild and palatable for M. ung.is ideal rodenticidi for pesf control.
