Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has established maximum residue limits (MRLs) for the chemicals and commodities captured below.

These MRLs were proposed in the consultation document published on 18 February 2009, Proposed Maximum Residue Limit PMRL2009-06, Addendum to the document: Transitioning the Legal Establishment of Maximum Residue Limits (MRL) for Pesticides from the Food and Drugs Act to the Pest Control Products Act: Consultation on Proposed MRLs. The PMRA received no comments in response to this consultation.

To comply with Canada's international trade obligations, consultation on the proposed MRLs was also conducted internationally by notifying the World Trade Organization, as coordinated by the Standards Council of Canada. Appendix II summarizes the comment received during the World Trade Organization consultation and provides the PMRA's response to this comment. The comment received had no impact on the MRLs for fosetyl-aluminum, which are established as proposed in PMRL2009-06.

The following MRLs take legal effect as of the publication date of this document and are in addition to the MRLs already established for each chemical.

Appendix II - Comment and Response

Comment

The United States Government requested that Canada consider revising its proposed 0.05 ppm MRL for fosetyl-aluminum in or on ginseng and caneberries to 0.1 ppm, the level currently enforced in Mexico and the United States, to promote the free trade of agricultural products and minimize trade irritants.

Response

The supervised crop field trials, which formed the basis of the proposed MRL of 0.05 ppm for fosetyl-aluminum in/on caneberries and ginseng, were conducted according to the United States approved label rate (20 lbs product/acre/season for caneberries and 45 lbs product/acre/season for ginseng). When sampled according to the labelled preharvest interval, residues of fosetyl-aluminum did not exceed the validated 0.05 ppm limit of quantitation of the analytical method. Therefore, there is no scientific justification to revise the MRL for fosetyl-aluminum from 0.05 ppm to 0.1 ppm for either of the commodities.

Although the MRL/tolerances may be numerically different, there is no expectation that, if used according to the registered American label, the residues of fosetyl-aluminum will exceed the maximum level of 0.05 ppm (method limit of quantitation) reported in the trials.
