USDA Declares Ralstonia Eradicated
On June 11, USDA’s Animal and Plant Health Inspection Service (APHIS) announced the successful completion of actions taken by federal and state plant health officials to eliminate Ralstonia solanacearum race 3 biovar 2 from U.S. greenhouses. This announcement comes just two months after the pathogen was first detected on geranium (Pelargonium) in a Michigan greenhouse in April.
AmericanHort worked closely with APHIS and state officials toward the goal of a successful eradication effort with the least possible disruption of the industry during a Spring season that was already challenging due to COVID-19 pandemic-related market disruptions. In total, the response involved more than 650 facilities in 44 States. However, only a handful of operations were actually confirmed to have limited numbers of plants confirmed with the pathogen.
R. solanacearum race 3 biovar 2 can cause a wilt disease in several important agricultural crops such as potatoes, tomatoes, peppers, and eggplant. This was the first confirmed case of this pathogen in U.S. greenhouses since 2004.
