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 edible-podded legume vegetables (crop subgroup 6A) and succulent shelled pea and bean (crop subgroup 6B) to the product label of Acapela Fungicide containing technical grade picoxystrobin, is acceptable. The specific uses approved in Canada are detailed on the label of Acapela Fungicide, Pest Control Products Act Registration Number 30470.
The evaluation of this picoxystrobin 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 picoxystrobin is being conducted via this document (see Next steps). 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 picoxystrobin, are as follows.
| Common name | Residue definition | MRL (ppm)Table 1 Footnote 1 | Food commodity |
|---|---|---|---|
| Picoxystrobin | Methyl (αE)-α-(methoxymethylene)-2-[[[6-(trifluoromethyl)-2-pyridinyl]oxy]methyl]benzeneacetate | 2.0 | Edible-podded legume vegetables (crop subgroup 6A) |
| 0.9 | Succulent shelled pea and bean (crop subgroup 6B) | ||
|
|||
An MRL is 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 the Canada.ca 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 picoxystrobin 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 picoxystrobin in or on the petitioned commodities on the Codex Alimentarius Pesticide Index webpage.
Next steps
The PMRA invites the public to submit written comments on the proposed MRLs for picoxystrobin 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.
Appendix I
Summary of field trial data used to support the proposed maximum residue limits
Residue data for picoxystrobin were submitted to support the use of Acapela Fungicide on edible-podded legume vegetables (crop subgroup 6A) and succulent shelled pea and bean (crop subgroup 6B).
Maximum residue limits
The recommendation for maximum residue limits (MRLs) for picoxystrobin was based upon the submitted field trial data, and the guidance provided in the OECD MRL Calculator. Table A1 summarizes the residue data used to calculate the proposed MRLs for edible-podded legume vegetables (crop subgroup 6A) and succulent shelled pea and bean (crop subgroup 6B).
| Commodity | Application method/ Total application rate (g a.i./ha)Table A1 Footnote 1 | Preharvest interval (days) | Lowest average field trial residues (ppm) | Highest average field trial residues (ppm) |
|---|---|---|---|---|
| Edible-podded beans | Foliar Broadcast/440 | 0 | 0.107Table A1 Footnote 2 | 0.433Table A1 Footnote 2 |
| Edible-podded peas | Foliar Broadcast/440 | 0 | 0.293Table A1 Footnote 2 | 0.789Table A1 Footnote 2 |
| Succulent shelled beans | Foliar Broadcast/440 | 0 | <0.01Table A1 Footnote 2 | 0.817Table A1 Footnote 2 |
| Succulent shelled peas | Foliar Broadcast/440 | 0 | <0.01Table A1 Footnote 2 | 0.031Table A1 Footnote 2 |

Following the review of all available data, MRLs as proposed in Table 1 are recommended to cover residues of picoxystrobin. Residues of picoxystrobin 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.
