Under the authority of the Pest Control Products Act, Health Canada’s Pest Management Regulatory Agency (PMRA) is proposing to revise the established maximum residue limit (MRL) for fludioxonil on mangoes to permit the import and sale of foods containing such residues.
Fludioxonil is a fungicide currently registered in Canada for use on various commodities.
The PMRA must determine the quantity of residues that are likely to remain in or on the imported food commodities when fludioxonil is used according to label directions in the exporting country, and that such residues will not be a concern to human health. This quantity is then legally established as an MRL on the corresponding imported commodity. 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.
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 fludioxonil, is as follows.
|Residue Definition||MRL (ppm)Footnote 1||Food Commodity|
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
The MRL proposed for fludioxonil in Canada is the same as the corresponding Codex MRLFootnote 1. A listing of established Codex MRLs is available on the Codex Alimentarius Pesticide Index webpage, by pesticide or commodity.
Table 2 compares the MRL proposed for fludioxonil in Canada with the corresponding American tolerance. The American tolerance is listed in the Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide.
|Food Commodity||Canadian MRL (ppm)||American Tolerance (ppm)|
The PMRA invites the public to submit written comments on the proposed MRL for fludioxonil 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 they are entered into the Maximum Residue Limit Database.
Summary of Field Trial Data Used to Support the Proposed Maximum Residue Limit
Residue data for fludioxonil in mangoes were submitted to support the maximum residue limit on imported mangoes.
Maximum Residue Limit
The recommendation for a maximum residue limit (MRL) for fludioxonil was based upon the residues observed in mangoes treated according to label directions in the exporting countries, and the guidance provided in the OECD MRL Calculator. Table A1 summarizes the residue data used to calculate the proposed MRL for imported mangoes.
|Commodity||Application Method/ Total Application Rate||Post-harvest Treatment Interval (days)||Minimum Field Trial Residue (ppm)||Maximum Field Trial Residue (ppm)|
|Mango – whole fruit||Post-harvest dip application / 29.6-34.5 g a.i./100L waterFootnote 1||0||0.26||1.23|
- Footnote 1
g a.i./100 L = grams of active ingredient per 100 litres of water
Following the review of all available data, the MRL as proposed in Table 1 is recommended to cover residues of fludioxonil. Residues of fludioxonil in this imported crop commodity at the proposed MRL will not pose an unacceptable risk to any segment of the population, including infants, children, adults and seniors.

The Codex Alimentarius Commission is an international organization under the auspices of the United Nations that develops international food standards, including MRLs.
