Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has granted conditional registration to technical grade spiromesifen and the end-use product Forbid 240 SC Insecticide/Miticide for use in Canada on tuberous and corm vegetables (Crop Subgroup 1C), leafy vegetables (Crop Groups 4 and 5), fruiting vegetables (Crop Group 8), cucurbit vegetables (Crop Group 9), field corn, greenhouse vegetables (cucumbers, peppers and tomatoes) and strawberries. The specific uses approved in Canada are detailed on the Forbid 240 SC Insecticide/Miticide, Pest Control Products Act Registration Number 28590.

Corresponding maximum residue limits (MRLs) were proposed in the consultation document published on 20 December 2007, Proposed Maximum Residue Limit PMRL2007-15, Spiromesifen. The PMRA received no comments in response to this consultation.

To comply with Canada's international trade obligations, consultation on the proposed MRLs 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.
