R. solanacearum race 3 biovar 2 can cause a wilt disease in several important agricultural crops such as potatoes, tomatoes, peppers, and eggplant, and several ornamentals. This was the first confirmed case of this pathogen in U.S. greenhouses since 2004.
“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,” says Craig Regelbrugge, Senior Vice President, Advocacy and Research at AmericanHort. “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.”
APHIS continues to strengthen overseas safeguards, improve diagnostics, increase treatment options, and continually assess pathways to better protect American agriculture from this and other high-consequence plant pests and diseases.
