Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has added a new use for cucurbit vegetables (Crop Group 9; 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 11 April 2008, Proposed Maximum Residue Limit PMRL2008 04, 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 MRLs 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 commodities completing the cucurbit crop group 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)
