Blightline June 3
No late blight has been reported in ND or MN. Late blight severity values are beginning to accumulate in northern and eastern ND and northwestern MN. Late has been reported in Walla Walla County in southern Washington on June 1.
It is not too early to remind the potato community to prepare for late blight. We did have late bight in central MN last year, and infected seed could from other areas could act as a source of inoculum for our region. Continuing wet weather will provide conditions favorable for late blight if inoculum is present.
