For the control of Horn Flies (including pyrethroid-resistant Horn Flies), Gulf Coast Ticks and Spinose Ear Ticks on beef and non-lactating dairy cattle and as an aid to control Face Flies.

All mature animals in the herd should be tagged. For adequate control of Horn Flies attach one tag per animal. For optimum control of Horn Flies, Gulf Coast Ticks, and Spinose Ear Ticks, and as an aid in the control of Face Flies, attach one tag to each ear (two per animal). Replace as necessary. Co-Ral Plus® Insecticide Cattle Ear Tags have been proven to be effective against Horn Flies for three to five months. Use Allflex® Global Applicator with the red pin and black clip to apply tags to cattle.

Apply as indicated (Figures 1-4). Calves less than 3 months of age should not be tagged as ear damage may result. Remove tags at end of fly season or prior to slaughter.

Continual exposure of Horn Flies to a single class of insecticide (e.g. pyrethroids or organophosphates) may lead to the development of resistance to that class of insecticide. In order to reduce the possibility of Horn Flies developing resistance it is important to rotate the class of insecticide used and/or the method of Horn Fly control on a seasonal basis. Co-Ral Plus Insecticide Cattle Ear Tags contain the organophosphate insecticides coumaphos and diazinon.
