Blightline July 8, 2014
No late blight has been reported in our region. Late blight severity values continue to accumulate, particularly in the northeastern quarter of ND. All stations in this have reached the late blight threshold of 15 and conditions are favorable for late blight to develop if inoculum is present. Application of a protectant fungicide such as mancozeb or chlorothalonil is recommended. A protectant fungicide should be applied just before row closure or when late blight severity values reach 15.
