Under the authority of the  Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has concluded that the addition of new uses on triticaleto the product label of Twinline Fungicide, containing technical grade metconazole and pyraclostrobin, is acceptable. The specific uses approved in Canada are detailed on the label of Twinline Fungicide, Pest Control Products Act Registration Number 30337.

The evaluation of this application indicated that the end-use product has merit and value and the human health and environmental risks associated with the new uses are acceptable. Details regarding the registration can be found in the corresponding Evaluation Report available in the Pesticides and Pest Management section of Health Canada's website, under Public Registry, Pesticide Product Information Database.^{Footnote 1}

Before registering a pesticide for food use in Canada, the PMRA must determine the quantity of residues that are likely to remain in or on the food when the pesticide is used according to label directions and that such residues will not be a concern to human health. This quantity is then legally established as a maximum residue limits (MRL). An MRL applies to the identified raw agricultural food commodity as well as to any processed food product that contains it, except where separate MRLs are specified for the raw agricultural commodity and a processed product made from it.

Consultation on the proposed MRL for metconazole is being conducted via this document (see Next Steps, the last section of this document). An MRL for pyraclostrobin is being promulgated under a separate MRL action.

To comply with Canada's international trade obligations, consultation on the proposed MRL is also being conducted internationally by notifying the  World Trade Organization, as coordinated by the  Standards Council of Canada.

The proposed MRL for metconazole in Canada in or on food is as follows.

A complete list of all pesticide MRLs established in Canada, as of the date indicated, can be found on the Maximum Residue Limits for Pesticides webpage in the Pesticides and Pest Management section of Health Canada's website.

International Situation and Trade Implications

MRLs may vary from one country to another for a number of reasons, including differences in pesticide use patterns and the locations of the field crop trials used to generate residue chemistry data. The proposed MRL for metconazole in Canada differs from the corresponding tolerance established in the United States (tolerances are listed in the  Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide). Currently, there are no Codex MRLs^{Footnote 2} listed for metconazole in or on any commodity on the Codex Alimentarius  Pesticide Residues in Food website.

Next Steps

The PMRA invites the public to submit written comments on the proposed MRL for metconazole up to 75 days from the date of publication of this document. Please forward your comments to Publications. The PMRA will consider all comments received before making a final decision on the proposed MRL for metconazole and posting a corresponding Established Maximum Residue Limit document in the Pesticides and Pest Management section of Health Canada's website.
