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 greenhouse eggplant to the product label of Decree 50 WDG Fungicide, containing technical grade fenhexamid, is acceptable. The specific uses approved in Canada are detailed on the label of Decree 50 WDG Fungicide, Pest Control Products Act Registration #26132.

The evaluation of this fenhexamid 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 MRL for fenhexamid is being conducted via this document (see Next Steps). A summary of the field trial data used to support the proposed MRL can be found in Appendix I.
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 fenhexamid, is as follows:

Table 1 Proposed Maximum Residue Limit for Fenhexamid
Common Name Residue Definition MRL (ppm)Footnote 1 Food Commodity
Fenhexamid N-(2,3-dichloro-4-hydroxyphenyl)-1-methylcyclohexanecarboxamide 2.0 Eggplants

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 MRL proposed for fenhexamid in Canada is the same as corresponding American tolerance and Codex MRL. American tolerances are listed in the Electronic Code of Federal Regulations, 40 CFR Part 180, by pesticide. A listing of established Codex MRLs is available on the Codex Alimentarius Pesticide Index webpage, by pesticide or commodity.

Next Steps

The PMRA invites the public to submit written comments on the proposed MRL for fenhexamid 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.

Appendix I

Summary of Field Trial Data Used to Support the Proposed Maximum Residue Limit

Previously reviewed residue data from field trials conducted on greenhouse peppers were reassessed in the framework of this petition.

Maximum Residue Limit

The recommendation for the maximum residue limit (MRL) for fenhexamid was based upon the field trial data on file, and the guidance provided in the OECD MRL Calculator. Table A1 summarizes the residue data used to calculate the proposed MRL for eggplants.

Table A1 Summary of Field Trial Data Used to Support the MRL

Application Method/Total Application Rate
(g a.i./ha)Footnote 2
Preharvest Interval (days) Lowest Average Field Trial Residues
Highest Average Field Trial Residues
Greenhouse peppers Foliar application/ 2150-2274 1 0.20 0.42

Following the review of all available data, the MRL as proposed in Table 1 is recommended to cover residues of fenhexamid. Residues of fenhexamid in this crop commodity at the proposed MRL will not pose an unacceptable risk to any segment of the population, including infants, children, adults and seniors.
