Blightline August 20, 2013

No additional late blight has been reported in our area. Late blight severity values have generally remained stable at all sites, and conditions have not been 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
