Please follow the link below for an update on disease threshold/forecast values. We are not yet at threshold for either late blight or early blight but weather in WI looks to be generally favorable for disease for the upcoming few days. The DSVS for earlier planted potatoes in some locations could reach threshold by later in the week. These values are posted to our UW Vegetable Pathology website 2X a week. Typically on Tuesdays and Fridays.
