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 cereal grains (Crop Group 15; see Appendix I) to the product labels of Quilt Fungicide and Tilt 250E Fungicide, containing technical grade propiconazole, is acceptable. The specific uses approved in Canada are detailed on the labels of Quilt Fungicide and Tilt 250E Fungicide, Pest Control Products Act Registration Number 28328 and 19346, respectively.
The evaluation of these propiconazole applications indicated that the end-use products have merit and value and that the human health and environmental risks associated with the new uses are acceptable. Details regarding the registrations can be found in the corresponding Evaluation Reports that are available in the Pesticides and Pest Management section of Health Canada's website, under Public Registry, Pesticide Product Information Database.1
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.
In addition, the PMRA is consulting on proposed MRLs for propiconazole on commodities previously registered in Canada for which MRL consultations were not conducted. These MRLs are included in Table 1 and are supported by the summary residue data captured in Appendix II of this PMRL.
Consultation on the proposed MRLs for propiconazole is being conducted via this document (see Next Steps, the last section of this document).
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 Standards Council of Canada.
The proposed MRLs for propiconazole in Canada in or on food, to replace or be added to those MRLs already legally established, are as follows.
| Common Name | Residue Definition | MRL (ppm) | Food Commodity |
|---|---|---|---|
| Propiconazole | 1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole, including all metabolites containing the 2,4-dichlorophenyl-1-methyl substituted moiety | 0.25* | Edible-podded legume vegetables (Crop Subgroup 6A) |
| 0.2 * | Dry soybeans | ||
| 0.1* | Dried shelled pea and bean, except soybean (Crop Subgroup 6C)**, liver of poultry | ||
| 0.05*** | Buckwheat, field corn, pearl millet, popcorn grain, proso millet, rice, rye, sorghum, sweet corn kernels plus cob with husks removed, teosinte, triticale, wild rice | ||
| 0.05 * | Succulent shelled pea and bean (Crop Subgroup 6B); eggs; meat and meat byproducts (except liver) of poultry; meat and meat byproducts (except liver and kidney) of cattle | ||
| 0.01 * | Milk |
* The proposed MRLs are for previously registered commodities, which are supported by data attached under Appendix II.
** The proposed MRL is to replace the currently established MRL of 0.05 ppm for a number of dry beans and include all subgroup commodities.
*** The cereal grains barley, oats and wheat are not listed given that MRLs of 0.05 ppm are already established.
MRLs are proposed for each commodity included in the listed crop groupings in accordance with Appendix I.
A complete list of all MRLs established in Canada can be found on the Maximum Residue Limits for Pesticides webpage in the Pesticides and Pest Management section of Health Canada's website.
International Situation and Trade Implications
MRLs may vary from one country to another for a number of reasons, including differences in pesticide use patterns and the locations of the field crop trials used to generate residue chemistry data. For livestock commodities, differences in MRLs can also be due to different livestock feed items and practices. Table 2 identifies the differences between the MRLs proposed for propiconazole in Canada, the corresponding tolerances established in the United States (tolerances are listed in the Electronic Code of Federal Regulations,
40 CFR Part 180, by pesticide) and Codex MRLs.2 A listing of Codex MRLs is available on the Codex Alimentarius Pesticide Residues in Food website.

Next Steps
The PMRA invites the public to submit written comments on the proposed MRLs for propiconazole up to 75 days from the date of publication of this document. Please forward your comments to Publications (see the contact information on the cover page of this document). The PMRA will consider all comments received before making a final decision on the proposed MRLs for propiconazole and posting a corresponding Established Maximum Residue Limit document in the Pesticides and Pest Management section of Health Canada's website.

Basis for MRLs Proposed for Livestock Commodities
The proposed MRLs for livestock commodities result from the consumption of previously registered feed item uses. However, as there is no expectation of quantifiable residues in livestock matrices as a result of such consumption, MRLs for these commodities are based on the limit of quantitation (LOQ) of the corresponding analytical methodology used to determine residues.
| Food Commodity | Analytical Method LOQ (ppm) |
Recommended MRL |
|---|---|---|
| Liver of poultry | 0.1 | 0.1 ppm |
| Eggs, meat and meat byproducts (except liver) of poultry | 0.05 | 0.05 ppm |
| Meat and meat byproducts (except liver and kidney) of cattle | 0.05 | 0.05 ppm |
| Milk | 0.01 | 0.01 ppm |
