Insecticidal Ear Tags: What to Know About Fly Control for Cattle
|Ear tags impregnated with traces of insecticide can provide excellent control of cattle pests like horn flies and may also limit face fly populations. University research indicated that effectively controlling these pests can increase stocker cattle gains by 15-25 pounds.|
What is the best strategy to minimize development of resistance to chemical compounds?
Pyrethroid-resistant horn flies are found in many parts of the country and developing resistance depends on many factors. Judging by the flies affecting your herd, an alternate method of control like organophosphates for one to three years followed by one year of pyrethroid use may be appropriate. And now there are two new classes of fly tag insecticides to combat pyrethroid and organophosphate resistant flies – endosulfin which has been on the market for a few years, and the newest – abamectin. This is a mixture of avermectins commonly used as an insecticide and/or anthelmintic (dewormer). Its more familiar derivatives are Ivermectin, Selamectin and Doramectin. Abamectin provides an ideal alternative in a strategic fly control rotation.
