Under the authority of the Pest Control Products Act, Health Canada’s Pest Management Regulatory Agency (PMRA) has concluded that the addition of new uses on stone fruits (Crop Group 12-09) and caneberries (Crop Group 13-07A) to the product label of Sivanto™ Prime Insecticide, containing technical grade flupyradifurone, is acceptable. The specific uses approved in Canada are detailed on the label of Sivanto™ Prime Insecticide, Pest Control Products Act Registration Number 31452.
The evaluation of this flupyradifurone application indicated that the end-use product has value and the human health and environmental risks associated with the new uses are acceptable.
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 established 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.
Consultation on the proposed MRLs for flupyradifurone is being conducted via this document (see Next Steps, the last section of this document). A summary of the field trial data used to support the proposed MRLs can be found in Appendix I.
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 the Canada’s Notification Authority and Enquiry Point.
The proposed MRLs, to be added to the MRLs already established for flupyradifurone, are as follows.
|Common Name||Residue Definition||MRL (ppm)Table 1 footnote 1||Food Commodity|
|Flupyradifurone||4-[[(6-chloro-3-pyridinyl)methyl](2,2-difluoroethyl)amino]-2(5H)-furanone||5.0||Caneberries (crop subgroup 13-07A)|
|1.5||Stone fruits (crop group 12-09)|
MRLs are proposed for each commodity included in the listed crop groupings in accordance with the Residue Chemistry Crop Groups webpage in the Pesticides and Pest Management section of Health Canada’s 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
The MRLs proposed for fluoxastrobin 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 fluoxastrobin in or on any commodity on the Codex Alimentarius Pesticide Residues in Food and Feed webpage.
The PMRA invites the public to submit written comments on the proposed MRLs for flupyradifurone 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 flupyradifurone in cherries, peaches, plums, raspberries, and blackberries were submitted to support the domestic use of Sivanto™ Prime Insecticide on stone fruits and caneberries. In addition, a processing study in treated plums was reviewed to determine the potential for concentration of residues of flupyradifurone into processed commodities.
Maximum Residue Limits
The recommendation for maximum residue limits (MRLs) for fluoxastrobin was based upon the residues observed in crops 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 crops.
|Commodity||Application Method / Total Application Rate (g a.i./ha)Table 1 footnote 1||Preharvest Interval (days)||Lowest Average Field Trial Residues (ppm)||Highest Average Field Trial Residues(ppm)||Experimental Processing Factor|
(Sweet and Tart)
|Plums||Foliar/410-420||13-15||0.028||0.169||5.3 (dried plums)|
|Raspberries and blackberries||Foliar/404-424||0||0.787||2.548||NA|
Following the review of all available data, MRLs as proposed in Table 1 are recommended to cover residues of flupyradifurone. Residues of flupyradifurone in these crop commodities at the proposed MRLs will not pose an unacceptable risk to any segment of the population, including infants, children, adults and seniors.
