Research findings could help farmers stop potato, tomato disease

A University of Florida scientist has pinpointed Mexico as the origin of the pathogen that caused the 1840s Irish Potato Famine, a finding that may help researchers solve the $6 billion-a-year disease that continues to evolve and torment potato and tomato growers around the world. A disease called “late blight” killed most of Ireland’s potatoes, while today it costs Florida tomato farmers millions each year in lost yield, unmarketable crop and control expenses. For more than a century, scientists thought the pathogen that caused late blight originated in Mexico. But a 2007 study contradicted earlier findings, concluding it came from the South American Andes.
