Summary

The purpose of this Re-evaluation Decision Document (RRD) is to notify registrants, pesticide regulatory officials and the Canadian public that Health Canada's Pest Management Regulatory Agency (PMRA) has re-evaluated the active ingredient paraquat dichloride and its associated uses as an herbicide to control many grasses and broad-leaved weeds on a variety of fruit, vegetable, and other field crops, nursery crops, shelterbelts and non-food aquatic sites.

On 22 October 2004, Proposed Acceptability for Continuing Registration (PACR) document PACR2004-41, Re-evaluation of Paraquat Dichloride, was published for consultation. The PMRA has reviewed the comments received and provides a response in Appendix I of this RRD. These comments did not result in any changes to the regulatory decision as described in PACR2004-41.

The PMRA has determined that this active ingredient is acceptable for continued registration. Mitigation measures to further protect workers and the environment are specified in Appendix II of this RRD. The registrants have been informed by letter of the specific requirements affecting their product registrations and the regulatory options available to comply with this decision.
