The attached spreadsheet lists the current residue chemistry crop groups used by the Health Canada PMRA, as well as the revisions to the crop groups. As a member of the ICGCC, Canada is updating the 20 residue chemistry crop groups currently listed in Section 9 of Regulatory Directive DIR98-02. The International Crop Grouping Consulting Committee (ICGCC) was subsequently established to update the crop groups to incorporate crops not already assigned to an existing crop group, to develop new crop groups, and to simplify the commodity terminology for the establishment of MRLs. In 2002, the International Crop Grouping Symposium recommended that the existing crop groups be updated to incorporate crops which were not currently members of a crop group. These crop groups, which are based on revisions in 1995, contain approximately 500 crops and correspond to those used by the United States Environmental Protection Agency The residue chemistry crop groups used by the PMRA are listed in Directive 98-02 Residue Chemistry Guidelines. Crop groups can also contain smaller and more closely related crop subgroups. Crop groups simplify the establishment of MRLs by using residue data for crops that are representative of the whole group to extend to all crops within the crop group. Individual crops are allocated to a crop group (CG) based on botanical and taxonomic criteria as well as on cultivation practices. To facilitate the establishment of Maximum Residue Limits (MRLs), the Health Canada Pest Management Regulatory Agency (PMRA) uses crop groups. ![]()
