Interpretive Summary:

Technical Abstract: The tomato late blight pandemic of 2009 made late blight into a household term in much of the Eastern United States. Many home gardeners and organic producers lost most if not all of their tomato crop, and their experiences were reported in the mainstream press. Some CSAs (Community Supported Agriculture) could not provide tomatoes to their members. This article reviews and documents the emergence of the 2009 pandemic, addressing several important questions: How did it happen? What was unusual about this event compared to previous late blight epidemics? What is the current situation in 2012, and what can be done?
