The Australian Pharmacy and Veterinary Medicine Association (APVMA) has announced a ban on livestock tag products containing diazinon, effective September 10, 2025. These products, used for buffalo fly control, include Y-Tex Warrior Insecticidal Cattle Ear Tags from Nutrien Ag Solutions Limited and Patriot and Co-Ral Plus Insecticide Cattle Ear Tags from Elanco Australasia Pty Ltd. Rural suppliers have reassured graziers that there is no need to panic buy these tags and that customers are expected to comply with the legal use-by date. The ban is expected to have significant impact on buffalo fly control programs and may increase reliance on selective breeding and non-chemical control methods. The decision is causing concern among agricultural communities and stakeholders, with discussions ongoing regarding alternative solutions.
