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):  Dimethenamid (ICS: 65.100.20, 67.080) 
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 (1430 — Dimeth enamid) (available in English and French; 
pages 3204-3207) 
6. Description of content:  Dimethenamid is registered under the Pest Control Products Act  
as a herbicide for the control of barnyard gr ass, crabgrass, Eastern black nightshade, fall 
panicum, foxtail, old witchgrass, redroot pigweed, and yellow nutsedge in field corn, 
kidney beans, soybeans, sweet corn, and wh ite beans as a pre-plant incorporated, pre-
emergent or early post-emergent treatment. By  virtue of subsection B.15.002(1) of the 
Food and Drug Regulations , the Maximum Residue Limit (MRL) for residues of 
dimethenamid in any food is 0.1 parts per million (p.p.m.).  
The Pest Management Regulatory Agency (PMRA) of Health Canada has recently 
approved an application to amend the registrati on of dimethenamid in order to allow its use 
for the control of barnyard grass, crabgrass, E astern black nightshade, fall panicum, foxtail, 
old witchgrass, redroot pigweed, and yellow  nutsedge in dry bulb onions as a post-
emergent treatment. This proposed regulat ory amendment would establish an MRL for 
residues of dimethenamid resulting from this use in dry bulb onions, 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 
dimethenamid of 0.01 p.p.m. in dry bulb onions would not pose an unacceptable health risk 
to the public.
