Consultation on pyriofenone, Proposed Maximum Residue Limit PMRL2023-44

Health Canada is consulting the public and seeking your feedback on a proposed maximum residue limit (MRL) increase due to a new pyriofenone use on greenhouse peppers and eggplants, and an MRL decrease due to a new pyriofenone use on greenhouse tomatoes. MRLs were previously set for peppers/eggplants and tomatoes grown in the field. The proposed revisions would apply to these crops grown in Canada. These new uses have already been approved in the United States and the proposed revisions to the Canadian MRLs are aligned with the established US tolerances for these crops.

An MRL is the highest amount of a specific pesticide residue allowed on a particular food commodity when a pesticide is used according to label directions. Although the MRLs are being revised to allow pyriofenone to be used on greenhouse crops grown in Canada, the MRLs apply to foods imported into Canada or grown in Canada.

Pyriofenone

• Pyriofenone is a fungicide currently registered in Canada for use on various field-grown vegetable commodities.
• Pyriofenone was first registered in Canada in 2016.

What is the proposed MRL decision

This consultation is on the proposed decision to accept the requests to

• Increase the MRL for pyriofenone on peppers/eggplants (crop subgroup 8-09B) from 0.3 ppm to 2.0 ppm;
• Decrease the MRL for pyriofenone on tomatoes (crop subgroup 8-09A) from 0.3 ppm to 0.2 ppm.

To address these requests, Health Canada conducted scientific evaluations to determine the potential impact of the new pyriofenone greenhouse uses in Canada. Results from these evaluations show that the new pyriofenone uses, and the resulting revised MRLs, would continue to meet Health Canada's requirements for the protection of human health.

Reporting to the people of Canada

Health Canada will make the results of this consultation available on this website. Once the decision on pyriofenone is finalized, the established MRLs will be legally in effect as of the date that they are entered into the MRL database. The MRL database is an online application that allows users to search for established MRLs, regulated under the Pest Control Products Act, for pesticides and food commodities.
