Re-evaluation Decision

Under the authority of the Pest Control Products Act, all registered pesticides must be regularly re-evaluated by Health Canada’s Pest Management Regulatory Agency (PMRA) to ensure that they continue to meet current health and environmental standards and continue to have value. The re-evaluation considers data and information from pesticide manufacturers, published scientific reports and other regulatory agencies. Health Canada applies internationally accepted risk assessment methods as well as current risk management approaches and policies.

Fosetyl-aluminum is a systemic fungicide used to manage various diseases on a wide range of agricultural crops, ornamentals and turf. Fosetyl-aluminum is applied as a soil drench treatment and foliar spray by conventional ground application equipment. Currently registered products containing fosetyl-aluminum are listed in Appendix I.

The regulatory approach for the re-evaluation of fosetyl-aluminum was first presented in the Proposed Re-evaluation Decision PRVD2017-19, Fosetyl-aluminum and Its Associated End-use Products which underwent a 90-day consultation period ending on period ending on 29 January 2018Footnote 1. PRVD2017-19 proposed no products for cancellation, however a number of uses and methods of application were proposed for cancellation due to occupational postapplication risks of concern. It was proposed to: prohibit use on cut flowers; increase restricted-entry intervals (REI) for apples, blackberries, highbush blueberries, red/black raspberries, grapes, brassica leafy vegetables, onions, spinach, and ornamental plants; and, prohibit drench applications to bedding plants.

Health Canada received comments relating to the health and value assessments. These comments are summarized in Appendix II of RVD2019-08 along with the responses by Health Canada. These comments and new data/information resulted in revisions to the risk assessments (see Science Evaluation Update section of RVD2019-08), and subsequently, in changes to the proposed regulatory decision as described in PRVD2017-19. A reference list of data used as the basis for the proposed re-evaluation decision is included in PRVD2017-19, and further data used in the re-evaluation decision is listed in Appendix VI of RVD2019-08.

Outcome of Science Evaluation

Following the consultation on the proposed re-evaluation decision, Health Canada revised the occupational risk assessment based on the comments received relating to the use of fosetyl-aluminum on bedding plants, and greenhouse and outdoor cut flowers. Health risks from fosetyl-aluminum and its associated end-use products have been shown to be acceptable for all uses of fosetyl-aluminum when used according to the revised label directions. The environmental risks associated with the use of fosetyl-aluminum and its related end-use products are acceptable when used according to the revised label directions, which include advisory statements and spray buffer zones.

Regulatory Decision for Fosetyl-aluminum

Health Canada has completed the re-evaluation of fosetyl-aluminum. Under the authority of the Pest Control Products Act, Health Canada has determined that continued registration of products containing fosetyl-aluminum is acceptable. An evaluation of available scientific information found that uses of fosetyl-aluminum products meet current standards for protection of human health and the environment when used according to revised label directions. Label amendments, as summarized below and listed in Appendix V of RVD2019-08, are required for all technical and end-use products. No additional data are requested.

Risk Mitigation Measures

Registered pesticide product labels include specific directions for use. Directions include risk mitigation measures to protect human health and the environment and must be followed by law. As a result of the re-evaluation of fosetyl-aluminum, Health Canada is requiring further risk-reduction measures in addition to those already identified on fosetyl-aluminum product labels. The key risk-reduction measures are summarized below. Refer to Appendix V of RVD2019-08 for details.

Next Steps

To comply with this decision, the required mitigation measures must be implemented on all product labels sold by registrants no later than 24 months after the publication date of this decision document. Appendix I lists the products containing fosetyl-aluminum that are registered under the authority of the Pest Control Products Act.
