Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has concluded that the addition of a new use on caraway to the product label of Lance WDG Fungicide, containing technical grade boscalid, is acceptable. The specific uses approved in Canada are detailed on the label of Lance WDG Fungicide, Pest Control Products Act Registration Number 27495.
The evaluation of this boscalid 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.
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 the Canada's Notification Authority and Enquiry Point.
The proposed MRL, to be added to the MRLs already established for boscalid, is as follows.
|Common name||Residue definition||MRL
(ppm)Table 1 Footnote 1
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
Currently, there are no American tolerances for boscalid in or on the petitioned commodity listed in the Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide, nor are there Codex MRLsFootnote 1 listed for boscalid in or on the petitioned commodity on the Codex Alimentarius Pesticide Index webpage.
The PMRA invites the public to submit written comments on the proposed MRL for boscalid 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 it is entered into the Maximum Residue Limit Database.
Summary of field trial data used to support the proposed maximum residue limits
Residue data for boscalid in caraway were submitted to support the domestic use of Lance WDG Fungicide on caraway.
Maximum residue limits
The recommendation for the maximum residue limit (MRL) for boscalid 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 MRL for caraway seeds.
|Commodity||Application method/Total application rate
(g a.i./ha)Table A1 Footnote 1
|Lowest average field trial residues
|Highest average field trial residues
Following the review of all available data, the MRL as proposed in Table 1 is recommended to cover residues of boscalid. Residues of boscalid in caraway seeds at the proposed MRL will not pose an unacceptable risk to any segment of the population, including infants, children, adults and seniors.
