Blightline July 11, 2014
No late blight has been reported in our region. Late blight severity values have generally stabilized, especially the non-irrigated sites. The cool weather forecast for next week is favorable for late blight. If severity values in your area have accumulated to 15, application of a protectant fungicide such as mancozeb or chlorothalonil is recommended. Many sites have reached this threshold. Late blight has not been found in MI as reported on Tuesday, but just across the border in Indiana. Late blight has been found in Cumberland County, Maine.
