Blightline August 20, 2018

No late blight is reported in ND or MN or MB. Late blight is reported in commercial fields in Adams and Marquette counties in Wisconsin. Conditions remain not favorable for late blight the past few days. Continue to apply protectant fungicides on a seven-day schedule for irrigated fields and a 7 to 10 day schedule for non-irrigated fields. Scout fields for late blight until vine kill and harvest.
