Recent changes to the Plant Protection Regulations monitoring Japanese barberry will see restrictions lifted on the importation and domestic movement of certain varieties of Japanese barberry (Berberis thunbergii).

     Subject to a control program administered by the Canadian Food Inspection Agency (CFIA), this amendment will allow for the importation and domestic movement of 11 rust-resistant varieties of Japanese barberry.

     The amendments to the Plant Protection Regulations mean that the following cultivars of Berberis thunbergii are now eligible for import, propagation and distribution in Canada: Aurea Nana, ‘Monomb’ Cherry Bomb, Concorde, ‘Tara’ Emerald Carousel, ‘Monlers’ Golden Nugget, ‘Bail­green’ Jade Carousel, Rose Glow, ‘Gentry’ Royal Burgundy, Royal Cloak, ‘Bailone’ Ruby Carousel and ‘Monry’ Sunsation.

     This control program will provide safeguards to prevent the introduction and propagation of wild barberry plants, and reduce the risk of black stem rust in Canada’s cereal growing areas.

     The CFIA will closely monitor the importation and propagation of approved barberry plants within Canada through ongoing requirements for plant protection import permits and foreign phytosanitary certificates as well as through regular inspection programs. Japanese barberry was previously prohibited because many varieties are susceptible to black stem rust disease, which can be a threat to cereal production. However, a number of rust-resistant varieties have been developed and marketed in the U.S. over the past 30 years.
