The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has confirmed the detection of Ralstonia solanacearum race 3 biovar 2 (RSr3b2) in a single variety of geranium plants located in a Michigan greenhouse. This particular type of Ralstonia can cause a wilt disease in several important agricultural crops such as potatoes, tomatoes, peppers and eggplant. This is the first confirmed case of RSr3b2 in a U.S. greenhouse since 2004. APHIS has taken immediate action to contain and eradicate the disease from the Michigan facility.
