"Blitecast" Potato Early Blight P-Day values

Early Blight P-Day values accumulate between the temperatures of 45°F to 75°F. The maximum of 10 P-Day values shows up if the temperature is a stable 70°F for a 24 hour period. These values reflect growth of potatoes, which occurs fastest at 70°F.

This model says that early blight will not develop until 300 P-Day values have been accumulated. Please note that this has not been tested in Oregon.
 

No early blight P-Day values for 2004

There will be no early blight P-Day values for 2004 due to lack of funding. Thank you to the Oregon Potato Commission for their support in the past few years.
