Proposed Maximum Residue Limit: Metaldehyde (PMRL2025-06)

The objective of the notified document PMRL2025-06 is to consult on the listed maximum residue limit (MRL) for metaldehyde that has been proposed by Health Canada’s Pest Management Regulatory Agency (PMRA).MRL (ppm)1,2 Raw Agricultural Commodity (RAC) and/or Processed Commodity0.15           Bushberries (crop subgroup 13-07B, except lingonberries and lowbush blueberries)1 ppm = parts per million2 Lingonberries and lowbush blueberries are not included in this crop subgroup MRL since they are also part of crop subgroup 13-07G (low growing berries) and there is already a registered use for metaldehyde on crop subgroup 13-07G. MRLs are currently established at 0.15 ppm in/on lingonberries and lowbush blueberries.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.
