Treatment and prophylaxis of psoroptic mange of sheep by a 10% w/w dip formulation of high CIS-cypermethrin.

Abstract

A 10% w/w dip formulation of high CIS-cypermethrin (Ecofleece sheep dip) was evaluated as a prophylactic and treatment method against Psoroptes ovis of sheep. A laboratory trial using groups of healthy sheep under challenge showed that, when dipped as directed for 1 min, they were protected against infection for at least 4 weeks. Twelve sheep infected with psoroptic mange at the laboratory were effectively treated by one dipping in Ecofleece. A field outbreak of psoroptic mange in a flock of 237 crossbred ewes was likewise successfully treated by just one dipping. As this formulation is also effective against blowfly myiasis it is a useful alternative to organophosphate dual purpose dips.
