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 soybeans to the product label of Stratego 250EC Fungicide, containing technical grade trifloxystrobin and propiconazole, is acceptable. The specific uses approved in Canada are detailed on the label of Stratego 250EC Fungicide, Pest Control Products Act Registration Number 27528.

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 that is available in the Pesticides and Pest Management section of Health Canada's Web site, 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 limit (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 trifloxystrobin is being conducted via this document (see Next Steps, the last section of this document).

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 trifloxystrobin in Canada in or on food, to replace the corresponding MRL already legally established, is as follows.

Table 1 - Proposed Maximum Residue Limit for Trifloxystrobin

Common Name	Residue Definition	MRL (ppm)	Food Commodity
ppm = parts per million The current residue definition for dry soybeans reflects parent chemical only but is proposed for revision in accordance with Table 1 above. Proposed to replace the currently established 0.02 ppm MRL.
Trifloxystrobin	methyl (α,E)-α-(methoxyimino)-2-[[[(E)-[1-[3- (trifluoromethyl)phenyl]ethylidene]amino]oxy] methyl]benzene acetate, including the metabolite (α,E)-α-(methyoxyimino)-2-[[[(E)-[1-[3- (trifluromethyl)phenyl]ethylidene]amino]oxy] methyl benzene acetic acid, expressed as trifloxystrobin	0.08	Dry soybeans

A complete list of all pesticide MRLs established in Canada can be found on the Maximum Residue Limits for Pesticides Web page in the Pesticides and Pest Management section of Health Canada's Web site.

International Situation and Trade Implications

The proposed MRL for trifloxystrobin in Canada is the same as 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, a Codex Alimentarius MRL ^{Footnote 2} has not been established for trifloxystrobin in or on soybeans. A listing of all established Codex MRLs is available on the Codex Alimentarius  Pesticide Residues in Food Web site.

Next Steps

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