Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has conditionally registered  technical grade pyrasulfotole and the end-use products AE 0317309 02 SE06 Herbicide and Infinity Herbicide for use in Canada on barley, oats, triticale and wheat. The specific uses approved in Canada are detailed on the product labels of AE 0317309 02 SE06 Herbicide and Infinity Herbicide, Pest Control Products Act Registration Numbers 28736 and 28738, respectively.

Corresponding domestic maximum residue limits (MRLs) were proposed in the consultation document published on 7 May 2008, Proposed Maximum Residue Limit PMRL2008-14, Pyrasulfotole. The PMRL also included an MRL for pyrasulfotole on rye to permit the import and sale of food containing these residues. The PMRA received no comments in response to this consultation.

To comply with Canada's international trade obligations, consultation on the proposed MRL was also conducted internationally by notifying the World Trade Organization, as coordinated by the Standards Council of Canada. No comments were received as a result of the World Trade Organization consultation.

The following MRLs are legally in effect as of the publication date of this document.
