Ralstonia Webinar: What You Need to Know

HRI Research • May 27, 2020

Ralstonia solancearum race 3 biovar 2 (R3B2), a federal quarantine pest, was recently confirmed in a single geranium variety in a greenhouse in Michigan, the first confirmed case in the US since 2004. Diseased geraniums planted in the landscape can potentially infect other plants, including tomatoes, potatoes, peppers, and eggplant and must be destroyed.



Since the detection was confirmed, AmericanHort has collaborated with the importer of the geranium and with USDA APHIS toward the goal of a rapid, targeted, and effective response that minimizes unnecessary interruption. HRI is proud to join this effort and host a webinar on the basics of R3B2, such as how it spreads and prevention strategies, to help educate the green industry. APHIS will be on hand to discuss the recent action plan, and Ball Horticultural Co will share their story.
