NOTIFICATION
1. Member to Agreement notifying:  CANADA
If applicable, name of local government involved:           
2. Agency responsible:  Department of Health
3. Products covered (provide tariff item number(s) as specified in national schedules
deposited with the WTO; ICS numbers may be provided in addition, where
applicable).  Regions or countries likely to be affected, to the extent relevant or
practicable: Diflufenzopyr
4. Title and number of pages of the notified document:  Proposed Amendment to the Food
and Drug Regulations (1194 –Diflufenzopyr) (pages 2955-2957)
5.Description of content: Under authority of the Pest Control Products Act , the Pest
Management Regulatory Agency (PMRA), of Health Canada, has approved an application
for the registration of the pest control product (pesticide) diflufenzopyr, as a herbicide for
the control of many annual and perennial broadleaf weed species in field corn, as a post-
emergent treatment. This proposed regulatory amendment would establish a Maximum
Residue Limit (MRL) under the Food and Drugs Act  for residues of diflufenzopyr and its
metabolite M1 resulting from this use in corn, 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
diflufenzopyr, including its metabolite M1, of 0.05 parts per million (p.p.m.) in corn would
not pose an unacceptable health risk to the public. This new MRL harmonizes with that
established by the United States Environmental Protection Agency.
6. Objective and rationale: [  X ] food safety,  [     ] animal health,  [     ] plant protection,
[    ] protect humans from animal/plant pest or disease,
[    ] protect territory from other damage from pests           
7. An international standard, guideline or recommendation does not exist [  X ].
If an international standard, guideline or recommendation exists, give the appropriate
reference and briefly identify deviations: The proposed Canada MRL of 0.05 p.p.m. on
corn will harmonize with the U.S.
