Consultation on the proposed special review decision of fosetyl-aluminum and its associated end-use products, PSRD2023-02

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting the public and seeking your comments on the proposed special review decision to continue allowing current uses of fosetyl-aluminum with updated risk mitigation measures. The consultation is only on the aspect of concern that triggered this special review, which is the potential risk to amphibians when exposed to fosetyl aluminum.

What is fosetyl-aluminum

Fosetyl-aluminum is a systemic fungicide that can be taken up by the roots or absorbed through the leaves of a plant. It provides control of various fungal diseases such as downy mildew. It has been registered for use in Canada since 1996 and was re-evaluated in 2019. Fosetyl-aluminum is registered for use on:

Fosetyl-aluminum is one of the few fungicides registered in Canada to suppress a quarantine pest, sudden oak death, in greenhouse and field-grown ornamental plants including certain trees.

What is the difference between re-evaluations and special reviews

Re-evaluations are cyclical reviews that determine if the pesticide meets current health, environment and value requirements. Re-evaluations are conducted using modern assessment techniques and current scientific information. If Health Canada's scientific information requirements or evaluation procedures change, pesticides may also be re-evaluated.

Special reviews may be initiated at any time if there are reasonable grounds to believe that the health, environment or value requirements of a pesticide are no longer met. A special review may be triggered by new information provided through various sources such as the Incident Reporting Program, other government partners, members of the public, or when an Organisation for Economic Co-operation and Development (OECD) member country prohibits all uses of a pesticide for health or environmental reasons.

Re-evaluations look at all aspects of a pesticide to ensure the pesticide meets current health, environment and value requirements, whereas special reviews only assess the aspect of concern that triggered the special review.

What is the reason for a special review of fosetyl-aluminum

The aspect of concern for this special review is that exposure to fosetyl-aluminum could potentially pose an unacceptable risk to amphibians. This is based on the scientific information relating to the effects of fosetyl-aluminum on amphibians provided to Health Canada as part of the Incident Reporting Program.

What is the proposed special review decision

Health Canada proposes to continue allowing the current uses of fosetyl-aluminum with updated risk mitigation measures to minimize the potential exposure of fosetyl-aluminum to amphibians:

Health Canada reviewed the latest information provided to the Pesticide Incident Reporting Program to update the amphibian risk assessment, along with information considered for the previous re-evaluation of fosetyl-aluminum. No additional information was identified from the public literature or from other jurisdictions. Results from the review show that with the implementation of updated risk mitigation measures, fosetyl aluminum continues to meet Health Canada's requirements for the protection of the environment.
