Under the authority of the Pest Control Products Act, Health Canada’s Pest Management Regulatory Agency (PMRA) is proposing to establish maximum residue limits (MRLs) for flutolanil on potatoes and peanuts to permit the import and sale of foods containing such residues.
Flutolanil is a fungicide not currently registered for use in Canada.
The PMRA must determine the quantity of residues that are likely to remain in or on the imported food commodities when flutolanil 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 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 flutolanil are as follows:
|Common Name||Residue Definition||MRL (ppm)Footnote 1||Food Commodity|
|Flutolanil||N-[3-(1-methylethoxy)phenyl]-2-(trifluoromethyl)benzamide and metabolites converted to [2-(trifluoromethyl)benzoic acid], expressed as flutolanil equivalents||0.5||Peanuts|
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 MRLs proposed for flutolanil in Canada are the same as corresponding American tolerances as listed in the Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide. Currently, there are no Codex MRLsFootnote 1 listed for flutolanil on potatoes and peanuts on the Codex Alimentarius Pesticide Index webpage.
The PMRA invites the public to submit written comments on the proposed MRLs for flutolanil 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.
Summary of Field Trial Data Used to Support the Proposed Maximum Residue Limits
Residue data for flutolanil in potatoes and peanuts were submitted to support the maximum residue limits on imported potatoes and peanuts. In addition, processing studies in treated potato and peanut were reviewed to determine the potential for concentration of residues of flutolanil into processed commodities.
Maximum Residue Limits
The recommendation for maximum residue limits (MRLs) for flutolanil was based upon the residues observed in crop commodities treated according to label directions in the exporting country, and the guidance provided in the OECD MRL Calculator. Table A1 summarizes the residue data used to calculate the proposed MRLs for imported potatoes and peanuts.
|Commodity||Application Method/ Total Application Rate||Preharvest Interval (days)||Minimum Field Trial Residues
|Maximum Field Trial Residues
|Experimental Processing Factor|
|Potatoes||Potato seed piece treatment/6.8-7.1 g a.i./45 kg seed pieceFootnote 1||Not applicable||<0.05||0.110||No concentration in processed fractions|
|Peanuts||Broadcast spray application/2.24 kg a.i./haFootnote 2||40||0.10||0.24||No concentration in processed fractions|
Following the review of all available data, MRLs as proposed in Table 1 are recommended to cover residues of flutolanil. Residues of flutolanil in these imported crop commodities at the proposed MRLs will not pose an unacceptable risk to any segment of the population, including infants, children, adults and seniors.
