Under the authority of the Pest Control Products Act, Health Canada’s Pest Management Regulatory Agency (PMRA) has received applications to register technical grade inpyrfluxam and the end-use products Excalia and Zeltera Fungicides for use in Canada on various commodities.

The evaluation of these inpyrfluxam applications indicated that the end-use products have value, and the human health and environmental risks associated with their proposed uses are acceptable. Details regarding these applications can be found in Proposed Registration Decision PRD2020-10, Inpyrfluxam, Excalia Fungicide and Zeltera Fungicide, posted to the website on 23 June 2020.

Before registering a pesticide for food use in Canada, the PMRA must determine the quantity of residues that are likely to remain in or on the food when the pesticide is used according to label directions and that such residues will not be a concern to human health. This quantity is then legally specified as a maximum residue limit (MRL). An MRL applies to the identified raw agricultural food commodity as well as to any processed food product that contains it, except where separate MRLs are specified for the raw agricultural commodity and a processed product made from it.

In addition, the PMRA is proposing to specify MRLs for inpyrfluxam on various commodities to permit the import and sale of food containing such residues. The PMRA has determined the quantity of residues that are likely to remain in or on the imported commodities when inpyrfluxam is used according to label directions in the exporting country, and that such residues will not be a concern to human health. Details regarding the proposed MRLs on imported commodities can also be found in PRD2020-10.

Consultation on the proposed MRLs for inpyrfluxam is being conducted via PRD2020-10. Information regarding the proposed MRLs can be found in Sections 3.5. and 7.1. Supporting field trial residue data are also provided in the PRD. The PMRA invites the public to submit written comments on the proposed MRLs for inpyrfluxam in accordance with the guidance found in PRD2020-10.

To comply with Canada’s international trade obligations, consultation on the proposed MRLs is also being conducted internationally by notifying the World Trade Organization, as coordinated by Canada’s Notification Authority and Enquiry Point.

The proposed MRLs for inpyrfluxam are as follows.

Inpyrfluxam 3-(Difluoromethyl)-N-[(3R)-2,3-dihydro-1,1,3-trimethyl-1H-inden-4-yl]-1-methyl-1H-pyrazole-4-carboxamide 0.01 Legume vegetables (succulent or dried) (crop group 6); cereal grains (crop group 15); rapeseeds (crop subgroup 20A) (revised); apples; eggs; fat, meat and meat byproducts of cattle, goats, hogs, horses, poultry and sheep; milk; peanuts; sugar beet roots

MRLs are proposed for each commodity included in the listed crop groupings in accordance with the Residue Chemistry Crop Groups webpage in the Pesticides section of the website.

MRLs established in Canada may be found using the Maximum Residue Limit Database on the Maximum Residue Limits for Pesticides webpage. The database allows users to search for established MRLs, regulated under the Pest Control Products Act, both for pesticides or for food commodities.

International situation and trade implications

Inpyrfluxam is a new active ingredient that is concurrently being registered in Canada and the United States. The MRLs proposed for inpyrfluxam in Canada are the same as corresponding tolerances to be promulgated in the United States, as shown in Table 2, except in some cases where American tolerances will not be established because there is no expectation of residues (as described under DIR2003-02 for seed treatment regulatory framework for Canada and the United States).

Once established, the American tolerances for inpyrfluxam will be listed inthe Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide.

Currently, there are no Codex MRLsFootnote 1 listed for inpyrfluxam in or on any commodity on the Codex Alimentarius Pesticide Index webpage.

Table 2 - Comparison of Canadian MRLs, American Tolerances and Codex MRLs (where different)
Food Commodity Canadian MRL (ppm) American Tolerance
Codex MRL
Legume vegetables (succulent or dried)(crop group 6) 0.01 0.01 (soybeans only) Not established
Cereal grains (crop group 15) 0.01 0.01 (corn: sweet, field and pop; rice grain) Not established
Rapeseeds (crop subgroup 20A) (revised) 0.01 Not established Not established

Next steps

The PMRA invites the public to submit written comments on the proposed MRLs for inpyrfluxam up to 75 days from the date of publication of this document. Please forward your comments to Publications. The PMRA will consider all comments received before making a final decision on the proposed MRLs. Comments received will be addressed in a separate document linked to this PMRL. The established MRLs will be legally in effect as of the date that they are entered into the Maximum Residue Limit Database.
