Diazinon Update

The (APVMA) has confirmed that all Diazinon based product registrations and label approvals will be cancelled from 10th September 2025 onwards. Diazinon, like many long-standing active ingredients, has undergone ongoing regulatory review, with the APVMA responsible for governing product registrations across farming, veterinary, and pet applications. What this means for our customers:
  • Until 10th September 2025: It remains legal for retailers, including Norco, to supply Diazinon-based products, and for farmers to purchase, possess, and use them.
  • From 10th September 2025 onwards: It will become illegal for retailers to supply, and for farmers to possess or use, any Diazinon-based products.
Our approach: At Norco, we have made the decision to cease stocking and selling Diazinon-based products ahead of the APVMA deadline. This proactive step ensures a smooth transition for our customers and allows us to focus on alternative solutions that will continue to meet your on-farm needs. Norco remains committed to supporting you through this change with trusted advice and suitable product options.
