Registration Decision StatementFootnote 1 for Mandipropamid

Health Canada's Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act and Regulations, is granting full registration for the sale and use of Mandipropamid Technical Fungicide and Revus Fungicide, containing the technical grade active ingredient mandipropamid, as a seed treatment on potato seed pieces to control late blight.

This decision is consistent with the Proposed Registration Decision PRD2016-20, Mandipropamid, which contains a detailed evaluation of the information submitted in support of this registration. The evaluation found that, under the approved conditions of use, the products have value and do not present an unacceptable risk to human health or the environment. See Appendix I for a summary of comments received during the consultation process as well as the PMRA's response to these comments.

Other Information

The relevant test data on which the decision is based (as referenced in PRD2016-20, Mandipropamid) are available for public inspection, upon application, in the PMRA's Reading Room (located in Ottawa). For more information, please contact the PMRA's Pest Management Information Service by phone (1-800-267-6315) or by e-mail (

Appendix I Comments and Responses


A comment was received seeking clarification on the reasons for the differences between the current MRL of 0.01ppm set in 2010 for the foliar use of mandipropamid and the USA's new mandipropamid tolerances of 0.09 ppm for potato and 0.15 ppm for wet peel.


Consultation on the revised mandipropamid MRL of 0.09 ppm for tuberous and corm vegetables (crop subgroup 1C which includes potatoes) was conducted via the Proposed Registration Decision document (PRD2016-20, Mandipropamid). Information regarding the proposed revised MRL can be found in Sections 3.3.4 and 7.1. Supporting field trial residue data are provided in Appendix I, Table 7.

Further to this, and as captured in Appendix II, Table 1 of the PRD, the proposed MRL of 0.09 ppm is the same as the corresponding American tolerance but differs from the Codex MRL of 0.01 ppm which is based on a foliar use.

In Canada, MRLs are specified under the Pest Control Products Act for the purposes of adulteration provision of the Food and Drugs Act. For this reason, PMRA does not establish MRLs for livestock feed items (i.e., wet peel).

Consultation on the proposed revised MRL of 0.09 ppm will also be conducted via a proposed Maximum Residue Limit (PMRL) document and by notifying the World Trade Organization, as coordinated by Canada's Notification Authority and Enquiry Point, to comply with Canada's international trade obligations.

Written comments on the proposed MRL for mandipropamid will also be accepted up to 75 days from the date of publication of the PMRL document.
