The Australian Pesticides and Veterinary Medicines Authority (APVMA) has released new timelines for decisions on 3 chemical reconsiderations.

The Proposed Regulatory Decision on anticoagulant rodenticides will be handed down prior to the end of this year. Publication had been forecast for mid-October. We have completed all assessments of the 8 active ingredients captured by the review and are now finalising the appropriate regulatory response to those assessments.

The Final Regulatory Decisions on paraquat and diquat will be handed down in mid-2026. Publication of the Final Decisions on paraquat and diquat had been expected prior to the end of this year. This has been deferred following the release by the U.S. Environmental Protection Agency (U.S. EPA) of an updated review of a recent study.

Released on 13 November 2025, the updated review presents U.S. EPA’s conclusion that there is greater uncertainty regarding the potential for paraquat to volatilise than previously considered.  The APVMA is reviewing its assessments of the volatility of paraquat and ensuring we have appropriately taken into account any concerns raised in the updated review from the U.S. EPA.  This additional time will allow consideration of the updated review and, if necessary, refinements to the APVMA’s risk assessments.
