Consultation on Dimethomorph and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2019-03

Notice to the reader:

The online consultation is now closed.

Dimethomorph is a commercial fungicide used to manage disease in some vegetable and fruit crops, ginseng, and ornamentals grown in fields and greenhouses. It is important for the management of potato late blight tuber rot, and sudden oak death, on many high value plants in nurseries and landscape plantings. Health Canada is proposing that products containing dimethomorph are acceptable for continued registration in Canada, provided that required label updates are made to further protect human health and the environment.

Those updates include:

  • Updates to personal protective equipment statements, restricted-entry intervals, and a label restriction against mist or fog applications to protect workers
  • Updates to best management practices to minimize bystander exposure
  • Label statements to mitigate dimethomorph entering aquatic environments and groundwater

Labels for dimethomorph products Forum, Zampro, and Acrobat can be found in the Pesticide Label Search database.

For more information on the proposed decision open the “Proposed Re-evaluation Decision”.
