Consultation on Ancymidol and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2021-10

Health Canada is consulting Canadians on the proposal to continue registration of ancymidol and all associated end-use products registered for sale and use in Canada, provided proposed updates to label directions are put in place.

As a result of the re-evaluation of ancymidol, these products were shown to have value as a plant growth regulator, used for height control of container-grown lilies, poinsettias and chrysanthemums. When the current label directions are followed, potential risks to human health (occupational, dietary, residential and bystander) and the environment (aquatic and terrestrial organisms and their habitats) are considered to be acceptable. However, label updates are proposed to meet the current labelling standards.

For a full list of products containing ancymidol, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.

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