Blightline August 3, 2017
Late blight has been confirmed in two commercial potato fields southeast of Perham in Ottertail County, MN. Late blight has also been reported near Veseleyville in Walsh County. We recommend that all potato fields in these areas 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. Curzate is recommended after a rain because it will kill late blight infections that are less than two days old.
