Google Maps of Phytophthora Infestans
Phytophthora infestans causes the serious potato disease known as late blight or potato blight. The organism can also infect tomatoes. The IPCC Tomato-Potato Smith Late Blight Map shows the current conditions for the disease throughout the United States.
The map uses three colors of map marker to show where there are currently low conditions for the disease, where spores are forming and where infection is possible. The map is updated daily and it is possible to view the daily maps produced going back to 2009.
