Consultation on Uniconazole-P and Its Associated End-use Products, Proposed Re evaluation Decision PRVD2019-09

Notice to the reader:

The online consultation is now closed.

Health Canada is proposing that products containing uniconazole-P are acceptable for continued registration in Canada, provided that the additional proposed risk mitigation measures are in place.

Uniconazole-P is used in the greenhouse ornamental industry and tomato transplant seedling production in greenhouses. For a list of products, consult Appendix I in the PRVD or visit the Pesticide Label Search database.

With respect to human health, dietary risks and risks to workers from most uses are considered to be acceptable under the current conditions of use. However, risks are not considered to be acceptable for workers conducting postapplication activities for greenhouse ornamentals grown for cut flowers. Therefore, the use on greenhouse ornamentals grown for cut flowers is proposed for cancellation. In addition, label updates are proposed to meet the current labelling standard and to improve clarity.

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