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 safety standards and that they 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.

Iron present as ferrous sulfate monohydrate or ferrous sulfate heptahydrate (hereafter referred to as ferrous sulfate) is an herbicide used to control the growth of moss in turf and lawns. Currently registered products containing ferrous sulfate are listed in Appendix I.

Health Canada has completed the re-evaluation for ferrous sulfate, and this document presents the final regulatory decision. Footnote 1 All pest control products containing ferrous sulfate that are registered in Canada are subject to this re-evaluation decision. This re-evaluation decision has gone through a 90-day consultation period as Proposed Re-evaluation Decision PRVD2019-01, Iron (Present as Ferrous Sulfate Monohydrate and Ferrous Sulfate Heptahydrate) and Its Associated End-use Products. Footnote 2

No comments were received during the consultation process. Therefore, this decision is consistent with the proposed re-evaluation decision stated in PRVD2019-01 with label statements updated to the current standard.

A reference list of all data used as the basis for the re-evaluation decision can be found in PRVD2019-01.

Regulatory Decision

Under the authority of the Pest Control Products Act, Health Canada has determined that continued registration of products containing ferrous sulfate is acceptable. Following a scientific review of the available information, Health Canada has determined that the health and environmental risks and the value of ferrous sulfate continue to be acceptable provided that the label updates, as listed in Appendix II, are implemented.

This document presents the final regulatory decision for the re-evaluation of ferrous sulfate. To comply with this decision, the required label amendments must be implemented on all product labels sold by registrants no later than 24 months after the publication date of this document. Registrants of products containing ferrous sulfate will be informed of the specific requirements affecting their product registration(s) and of the regulatory options available to them.
