Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has added a new use for leafy greens (Crop Subgroup 4A; see Appendix I) to the product label of Apron XL LS, containing technical grade metalaxyl-M. The specific use approved in Canada is detailed on the label of Apron XL LS, Pest Control Products Act Registration Number 25585.

Corresponding maximum residue limits (MRLs) were proposed in the consultation document published on 8 May 2008, Proposed Maximum Residue Limit PMRL2008-16, Metalaxyl. Residues of the resolved isomer metalaxyl-M are covered by MRLs established for metalaxyl, the unresolved racemate. The PMRA received no comments in response to this consultation.

To comply with Canada's international trade obligations, consultation on the proposed MRL was also conducted internationally by notifying the World Trade Organization, as coordinated by the Standards Council of Canada. No comments were received as a result of the World Trade Organization consultation.

The following MRLs, for the remaining commodities in the leafy greens crop subgroup, are legally in effect as of the publication date of this document and are in addition to the MRLs already established for metalaxyl.

Established Maximum Residue Limits for Metalaxyl

Common Name: Metalaxyl

Residue Definition: N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-DL-alanine methyl ester, including metabolites that can be converted to the 2,6-dimethylaniline moiety, each expressed as metalaxyl equivalents

Food Commodity* / MRL parts per million (ppm)

Amaranth, arugula, corn salad, dandelion leaves, dock, edible leaved chrysanthemum, endives, fresh chervil leaves, fresh parsley leaves, garden cress, garden purslane, garland chrysanthemum, head lettuce**, leaf lettuce**, orach leaves, radicchio, upland cress, winter purslane / 5.0

* The listed leafy green commodities (Crop Subgroup 4A) do not include New Zealand spinach, spinach or vine spinach as these commodities are already covered by an established MRL of 10 ppm for "spinach".
** The previously established MRL of 5.0 ppm for "lettuce" is replaced by separate entries for "head lettuce" and "leaf lettuce".

A complete list of all MRLs established in Canada can be found on the PMRA's MRL webpage.
