The Australian Pesticides and Veterinary Medicines Authority (APVMA) considers the priority of chemicals nominated for reconsideration prior to commencing a new reconsideration. In determining the chemicals to be prioritised for reconsideration, we assess the available information for chemicals previously nominated for reconsideration, chemicals that were nominated for spray drift reviews in 2010, public domain information including overseas regulatory decisions and information received from holders and the public raising concerns around specific chemicals.

The chemicals prioritised for commencing reconsideration are listed in Table 1 and the risk areas for reassessment are identified. The APVMA will commence scoping the full extent of the reconsideration of these chemicals as soon as possible, balancing risk, regulatory impact and workforce capacity. Where risks of these or other chemicals on the nomination list can be minimised through minor changes to instructions for use or through other regulatory mechanisms, action may be taken prior to commencing a full reconsideration.

Commencement of reconsiderations are announced in the APVMA Gazette.

Priorities for future chemical reconsiderations have been updated in 2024. 

The amendments made are detailed in Table 1. Chemicals prioritised for reconsideration are presented in Table 2 and chemicals which have been previously nominated and remain on the nomination list are identified in Table 3. This list may be added to as new information is received or identified and will be revisited regularly to confirm priority for reconsideration. Chemicals that were previously nominated for spray drift specific reconsiderations are listed in Table 4.

#Subject to change if new chemical-relevant risk information emerges.

The chemicals which have been previously nominated and remain on the nomination list are identified in Table 3. This list may be added to as new information is received or identified and will be revisited regularly to ensure that the prioritised chemicals are the most relevant.
