Consultation on Chondrostereum purpureum strain PFC2139 and its associated end-use products, Proposed Re-evaluation Decision PRVD2022-03

Health Canada is consulting Canadians on the proposal to continue registration of Chondrostereum purpureum strain PFC2139 and all associated end-use products registered for sale and use in Canada. To meet current standards, label amendments are proposed.

Chondrostereum purpureum strain PFC2139 is a naturally-occurring biological herbicide registered for use in Canada for inhibiting resprouting and regrowth from cut stumps of certain deciduous trees in rights-of-way and for forest vegetation management.

These products are shown to have value in providing a pest management solution. When the label directions are followed, potential risks to human health from occupational, dietary, and bystander exposure and to the environment are acceptable. In order to meet current standards, label updates for products containing C. purpureum strain PFC2139 are proposed.

For a full list of products containing Chondrostereum purpureum strain PFC2139 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".
