The results show 200×10^-6 AV vegetable in vitro to kill psoropotes in 139 min and in vivo to kill the parasite in 24 h, then to protect animal against infection by parasite for 72 d, the drug costs RMB 0.26 yuan/sheep. Iodine nitric F is a broad-spectrum drug against psoropotes, it killed parasite in 96 h in vivo, then protect animal against infection by parasite for 120 d, need RMB 0.50 yuan/sheep. The best wide universal medicine anti psoroptes is dint-good, validity the composition is a Avermectin, in this animal kill psoroptes time to 24 h.
