Proposed Maximum Residue Limit: Clethodim (PMRL2023-05)

The objective of the notified document PMRL2023-05 is to consult on the listed maximum residue limits (MRLs) for clethodim that have been proposed by Health Canada’s Pest Management Regulatory Agency (PMRA).MRL (ppm)1  Raw Agricultural Commodity (RAC) and/or Processed Commodity3.0                    Napa Chinese cabbages2.0                    Green onions (crop subgroup 3-07B)20.6                    Leaf petioles vegetables (crop subgroup 22B)0.3                    Buckwheat0.09                 Celeriac tops3, rutabaga tops31 ppm = parts per million2 The current established MRL for “Onions” at 0.2 ppm will be revised to “Dry bulb onions” at the same MRL value to reflect current terminology.3 Celeriac and rutabaga roots are excluded from this MRL action as an MRL of 0.3 ppm is already established on these commodities.The commodities included in the listed crop groups/subgroups can be found on the Residue Chemistry Crop Groups webpage (https://www.canada.ca/en/health-canada/services/consumer-product-safety/pesticides-pest-management/public/protecting-your-health-environment/pesticides-food/residue-chemistry-crop-groups.html) in the Pesticides section of the Canada.ca website.
