Re-evaluation decision for cymoxanil and associated end-use products

Under the authority of the Pest Control Products Act, all registered pesticides must be 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, as well as comments received during public consultations. Health Canada applies internationally accepted risk assessment methods as well as current risk management approaches and policies.

Cymoxanil is a fungicide registered for use on potatoes, field tomatoes and caneberries. Currently registered products containing cymoxanil can be found in the Pesticide Label Search and in Appendix I.

The Proposed Re-evaluation Decision PRVD2021-04, Cymoxanil and its End-use Products, Footnote 1 containing the evaluation of cymoxanil and proposed decision, underwent a 90-day consultation period ending on 26 May 2021. PRVD2021-04 proposed continued registration of cymoxanil and all associated end-use products registered for sale and use in Canada, provided that the proposed risk mitigation measures are in place.

The only comment received during the consultation period was from a technical grade active ingredient registrant, supporting the proposal and mitigation measures. Therefore, this decision document is consistent with the proposed re-evaluation decision stated in PRVD2021-04. A complete reference list of all information used in this final re-evaluation decision is included in the PRVD2021-04.

This document (Re-evaluation Decision RVD2021-09, Cymoxanil and Its Associated End-use Products) presents the final re-evaluation decision Footnote 2 for the re-evaluation of cymoxanil, including the required amendments (risk mitigation measures) to protect human health and the environment, as well as label amendments required to bring labels to current standards. All products containing cymoxanil that are registered in Canada are subject to this re-evaluation decision.

Health Canada has completed the re-evaluation of cymoxanil. Under the authority of the Pest Control Products Act, Health Canada has determined that continued registration of products containing cymoxanil is acceptable. An evaluation of available scientific information found that cymoxanil products meet current standards for protection of human health and the environment and have acceptable value when used according to revised conditions of registration which includes new mitigation measures. The required risk mitigation measures are summarized below and listed in Appendix II of RVD2021-09.

Risk mitigation measures
