Blightline July 31, 2017
Late blight has been confirmed in a commercial potato field in Pembina County, ND. The genotype is US23. Additional late blight has been reported in Walsh County, ND and Nelson County, ND. Because of the widespread findings of late blight, we recommend that all potato fields in northeastern ND should be thoroughly scouted for the presence of late blight. Growers in areas where late blight is present should apply a specialty fungicide with strong activity against late blight, such as Orondis, Revus Top or Ranman, Omega or Gavel.
