NOTIFICATION  
 
1. Member to Agreement notifying:   CANADA  
If applicable, name of local government involved: 
2. Agency responsible:   Pest Management Regulatory Agency (PMRA), Department of 
Health 
3. Products covered (provide tariff item numbe r(s) as specified in national schedules 
deposited with the WTO; ICS numbers should be provided in addition, where applicable):  Difenoconazole (ICS: 65.100.30, 67.060) 
4. Regions or countries likely to be affected, to the extent relevant or practicable:  Not 
stated. 
5. Title, language and number of pages of the notified document:   Proposed Amendment to 
the Food and Drug Regulations (1412 — Di fenoconazole) (available in English and 
French; pages 3189-3192) 
6. Description of content:  Difenoconazole is registered under the Pest Control Products Act  
as a fungicide for the control of a wide variety of fungi on barley, mustard, rapeseed 
(canola) and wheat as a seed treatment. Maximum Residue Limits (MRLs) have been 
established under the Food and Drugs Act  for residues of difenoconazole resulting from 
this use at 0.1 parts per million (p.p.m.) in wheat, 0.05 p.p.m. in mustard seed, 0.03 p.p.m. in rapeseed (canola) and 0.01 p.p.m. in barley . MRLs have also been established at 0.05 
p.p.m. in eggs and in meat and meat by-pr oducts of cattle, goats, hogs, poultry and sheep, 
and 0.01 p.p.m. in milk to cover residues in food derived from animals fed with crops 
treated with difenoconazole. By virtue of subsection B.15.002(1) of the Food and Drug 
Regulations , the MRL for other foods is 0.1 p.p.m.  
The Pest Management Regulatory Agency (PMRA) of Health Canada has recently 
approved an application to amend the registra tion of difenoconazole in order to allow its 
use for the control of 3-leaf dieback on field corn and sweet corn as a seed treatment. This 
proposed regulatory amendment would establis h an MRL for residues of difenoconazole 
resulting from this use in field corn grain (the kernels of field corn) and sweet corn kernel 
plus cob with husks removed, in order to permit the sale of food containing these residues.  
After the review of all available data, the PMRA has determined that an MRL for 
difenoconazole of 0.01 p.p.m. in field corn grai n and sweet corn kernel plus cob with husks 
removed would not pose an unacceptable health risk to the public.
