Abstract

The efficacy of pour-on formulations of alpha-cypermethrin, and spray formulations of either alpha-cypermethrin alone or cypermethrin combined with chlorfenvinphos, as well of chlorfenvinphos alone, was evaluated for the control of horn flies on grazing beef cattle. Fly population was monitored throughout 42 days post-treatment. The trial indicated that all used treatments provided at least a 90% reduction of horn (lies over six week study and. at present, should be considered as useful weapons for the control of Haematobia irritans in Brazil.
