Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has added new uses on cucurbit vegetables (Crop Group 9; see Appendix I) to the product label of Bravo 500 Agricultural Fungicide, containing technical grade chlorothalonil. The specific uses approved in Canada are detailed on the label of Bravo 500 Agricultural Fungicide, Pest Control Products Act Registration Number 15723.

Corresponding maximum residue limits (MRLs) were proposed for cucurbit vegetables without existing MRLs were proposed in the consultation document published on 19 November 2008, Proposed Maximum Residue Limit PMRL2008-29, Chlorothalonil. 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 and are in addition to the MRLs already established for chlorothalonil.
