Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has received applications to register the technical grade fenpropathrin and the end-use product Danitol EC Spray for use in Canada on various commodities.

The evaluation of these fenpropathrin applications indicated that the end-use product has value, and the human health and environmental risks associated with their proposed uses are acceptable. Details regarding these applications can be found in the Proposed Registration Decision PRD2020-05, Fenpropathrin and Danitol EC Spray, posted to the website on 8 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 limits (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.

MRLs have been previously established for all the commodities listed in PRD2020-05. One of these MRLs is being proposed for revision through the current fenpropathrin applications.

Consultation on the proposed revised MRL for fenpropathrin is being conducted via PRD2020-05. Information regarding the established and 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 revised MRL for fenpropathrin in accordance with the guidance found in PRD2020-05.

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

The proposed MRL, to replace the MRL already established for fenpropathrin, is as follows.

Table 1 Proposed Maximum Residue Limit for Fenpropathrin
Common Name Residue Definition MRL (ppm)Footnote 1 Food Commodity
Fenpropathrin cyano(3-phenoxyphenyl)methyl 2,2,3,3-tetramethylcyclopropanecarboxylate 0.15Footnote 2 Tree nuts (crop group 14-11)
Footnote 1

ppm = parts per million

Footnote 2

The MRL is proposed to replace the currently established MRL of 0.10 ppm for crop group 14.

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

MRLs may vary from one country to another for a number of reasons, including differences in pesticide use patterns and the locations of the crop field trials used to generate residue chemistry data.

Table 2 compares the MRL proposed for fenpropathrin in Canada with the corresponding American tolerance and Codex MRL.Footnote 1 American tolerances are listed inthe Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide. A listing of established Codex MRLs is available on the Codex Alimentarius Pesticide Index webpage, by pesticide or commodity.

Food Commodity Canadian MRL (ppm) American Tolerance
Codex MRL
Tree nuts (crop group 14-11) 0.15 0.10 (crop group 14) 0.15 (Tree nuts)

Next steps

The PMRA invites the public to submit written comments on the proposed MRL for fenpropathrin 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 MRL. Comments received will be addressed in a separate document linked to this PMRL. The established MRL will be legally in effect as of the date that it is entered into the Maximum Residue Limit Database.
