Famphur was not very effective in the control of ticks. The tropical horse tick (Anocentor nitens) is a species of serious concern to horse breeders and raisers in Florida mainly because it transmits Babesia caballi, the causative agent of equine piroplasmosis. A secondary concern is that heavy tick infestations may cause injury to the ears of the horse (Gladney etal. 1972). Data were unavailable on famphur control of ticks in horses however, famphur was 99.9 to 100% effective in controlling A. nitens in Hereford steers and heifers when fed in the diet at 5 mg/kg BW for 14 to 21 days. Famphur at 2.5 mg/kg BW in cattle diets for 7 days was only partially effective (39 to 87.5%) in controlling horse ticks (Gladney et al. 1972). Famphur — despite multiple treatments — was not effective in controlling cattle ticks (Haemaphysalis longicornis) when used as a pour-on at recommended application rates in weaned Hereford calves (Heath et al. 1980).
