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.
Streptomyces strain K61 is a bacterium that is used as a microbial pest control agent for the suppression of damping-off, root and crown rot, and wilt in various greenhouse ornamentals, vegetables, and herbs caused by common pathogenic fungi. The commercial end-use product is formulated as a wettable powder and is applied as a water suspension directly to the root zone/growing media of greenhouse plants. It can also be used as a seed treatment and is applied as a powder directly to seeds.
This consultation is open for comment from 25 July 2019 to 23 October 2019 (90 calendar days).
