Blightline August 12

No late blight has been reported or confirmed in our region of ND, MN or MB. We have not even had a suspicious sample submitted. Late blight has been reported in potatoes in Box Butte County, NE. The recent hot and dry weather has resulted in conditions unfavorable for late blight. Growers are encouraged to continue to apply protective fungicides for early and late blight control, as weather conditions can change quickly. Morning fog and dew are beginning to appear, and these can contribute to free moisture need for late blight infection. Continue to scout fields for late blight, concentrating in areas that are wet longer such as low areas, near shelterbelts or around pivot wells.
