Summary
Insecticide impregnated ear tags containing Diazinon or Dursban/cypermethrin combinations when applied at the rate of two tags per cow were more effective for the control of horn flies than tags that were applied at the rate of one per cow. With the Terminator® tag, the percentage control diminished after 8 t o 10 weeks when one tag was present, but the percentage control remained constant over a period of 15 weeks with two tags per cow. With the Max-Con@ tag control was Less satisfactory after 6 weeks when only one tag per cow was applied, but good control was received after 15 weeks on animals where two tags per cow were used.
