In a post that went up on Tues this week, I erroneously stated that an Additional Declaration was required for roses being exported to the U.S. from Canada. Please note that you do NOT need an A.D. under the GCP program for roses. It is up to each country to determine if RS R3bv2 is present.

Additionally, a specific pest module for RS R3bv2 is NOT required under the Greenhouse Certification Program (GCP), as roses are asymptomatic for this disease. You can read the UDSDA-APHIS and CFIA notification surrounding this issue here.

Read on for the full blog post about RS R3bv2 and the new export regulations that came into effect in May 2026.

In the efforts to prevent a quarantinable strain of Ralstonia from entering the United States, USDA-APHIS has changed importation rules for rose material for planting. This includes rose material coming from Canada. Under the new federal order, roses (Rosa spp.) grown in Canada must now have been grown entirely within Canada or the U.S.. This includes root stock and graft material.

This is to reduce a potential pathway for Ralstonia solanacearum Race 3 biovar 2 (Rs R3bv2) into the U.S., which can devastate solanaceous crops such as potato and tomato, as well as geraniums.

Note that as of September 16th 2026, UDSDA-APHIS and CFIA have released a notification that a specific pest module for RS R3bv2 is NOT required under the Greenhouse Certification Program (GCP), as roses are asymptomatic for this disease. Similarly, an Additional Declaration (AD) is NOT required by facilities under the GCP program. It is up to each country to determine if RS R3bv2 is present.
