Blightline August 15

Late blight has still not been reported in ND or MN despite very favorable conditions. Late blight severity values in our area continue to increase and conditions remain favorable for late blight because of the wet conditions and spotty showers. All sites except Linton, Mandan and Williston have exceeded the threshold value of 15. Severity values are high in all other locations and conditions have been favorable in southeastern ND and southwestern MN the past two days.
