Consultation on Streptomyces strain K61 and Its Associated End-use Product, Proposed Re evaluation Decision PRVD2019-08

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue all uses of Streptomyces strain K61. Streptomyces strain K61 is a biological fungicide used in the product Mycostop Biofungicide to suppress effects such as damping-off, root and crown rot, and wilt caused by pathogenic fungi on greenhouse plants.

Following a re-evaluation by Health Canada's Pest Management Regulatory Agency, no additional risk mitigation measures are proposed to product labels. To meet current labelling standards, Health Canada proposes labels clarify that the products are for greenhouse use only as well as update statements on personal protective equipment and the restricted-entry interval.

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