Cylence Ultra

Cylence Ultra Insecticide Cattle Ear Tags are for effective control of buffalo fly, including control of organophosphate resistant fly populations on beef and dairy cattle. Cylence Ultra is impregnated with Betacyfluthrin, a synthetic pyrethroid insecticide along with Piperonyl butoxide, which acts as a synergist. The insecticides are slowly released from the tag to protect cattle against buffalo fly for up to 4 months. Cylence Ultra dual tag system spreads the active and protects both flanks.



Contains two synthetic pyrethroid actives 80g/kg Betacyfluthrin and 200g/kg Piperonyl Butoxide
Long lasting protection, with up to 4 months buffalo fly control
Ideal seasonal rotation option with an organophosphate ie. Co-Ral Plus or Patriot
No withhold periods

Cylence Ultra ear tags will give effective control of buffalo flies if used on all animals (over 3 months of age). Cylence Ultra can be easily applied using an Allflex Universal (Red) or LazaMatic applicator. Attach two tags per animal (one tag per ear) to the back of the ear. Calves less than 3 months should not be tagged as ear damage may result.

It is recommended to treat cattle with ear tags during the peak fly season ie. when more susceptible cattle show 'fly worry', or when there are more than 200 flies per beef animal or 30 flies per dairy cow. To prolong the effectiveness of the chemical groups available for fly control, ensure that rotations occur both within a season and from season to season.
