Changes to import requirements for Rosa spp. plants for planting have recently been implemented by both Canada and the United States to address the risk of introduction of Ralstonia solanacearum Race 3 biovar 2 (Rs R3bv2) on this newly identified host.
The United States – Canada Greenhouse-Grown Plant Certification Program (GCP) Technical Requirements currently indicate that a pest module is required when a phytosanitary certificate requires an additional declaration (AD) for the same plants. However, the Animal and Plant Health Inspection Service (APHIS)-CFIA GCP Joint Administrative Group has determined that in this case, a pest module is not required.
The AD required by each country attests to the plants as being considered of United States or Canada origin and that Rs R3bv2 is not known to occur. The facility's list of plants in production provides enough information to demonstrate that the roses (Rosa spp.) are eligible. It is the responsibility of each country's National Plant Protection Organization (NPPO), not the facility, to determine whether Rs R3bv2 is absent in that country. Additionally, Rosa spp. shows no symptoms when infected; therefore, scouting of plants throughout production is not effective to detect this pest in roses.
