Canada Establishes Maximum Residue Limits for Flutriafol in Hops and Almond Nuts

August 22 2022

MRLs for Flutriafol, proposed by the Pest Control Products Act for food imported to and sold in Canada, have been adopted by the WTO. The MRLs entered into force on July 11, 2022.

MRLs for Flutriafol, proposed by the Pest Control Products Act for food imported to and sold in Canada, have been adopted by the WTO. The MRLs entered into force on July 11, 2022.

Flutriafol is a systemic broad-spectrum fungicide from the triazole group, which is usually used for seed dressing of cereals. Flutriafol is currently registered in Canada for use on apples, grapes, strawberries, and soybeans.

According to the Pest Control Products Act, Health Canada’s Pest Management Regulatory Agency (PMRA) accepted the request to specify maximum residue limits (MRLs) for flutriafol in the imported commodities of hops and almonds, to control or suppress certain fungal diseases. Health Canada has determined the quantity of residues that may remain in, or on, the imported commodities when flutriafol is used according to the label directions in the exporting country, and the residues will not be a concern to human health.

To comply with Canada’s international trade obligations, consultation on the proposed MRLs is also being conducted internationally by notification to the World Trade Organization (WTO), according to the document G/SPS/N/CAN/1433 (dated April 13, 2022) and this was adopted on July 11, 2022. [1]

The proposed MRLs, to be added to the MRLs already established for flutriafol, are summarized in Table 1.

Common Name Residue Definition



Food Commodity
Flutriafol (CAS # 76674-21-0) α-(2-fluorophenyl)-α-(4-fluorophenyl)-1H-1,2,4-triazole-1-ethanol 20 Hops (dried cones)
0.6 Almond nuts

The proposed MRLs of flutriafol were established via entry into the Canadian MRL database [2]. The database allows users to search for established MRLs, regulated under the Pest Control Products Act, both for pesticides and for food commodities.

What do the changes mean?

This update has the potential to impact farms and food producers. The imported commodities of hops and almonds for Canada must not be found with pesticide residues levels that exceed these MRLs. To ensure compliance with food safety regulations, food producers should seek professional advice.
