Blightline August 12, 2013
No additional late blight has been found or reported in our area since the single find in central MN near St. Cloud. The abnormally cool weather has resulted in morning dews, and these conditions are very favorable for late blight infection and spread. It remains important to scout fields for the presence of late blight and continue protectant fungicide applications until the end of the growing season. Concentrate scouting on low areas and along tree lines that stay wetter longer. It takes only 12 hours of wetness for late blight spores to infect.
