Late blight has been confirmed on potato in a field in North Carolina on May 2, 2012. Growers in Maryland and Delaware should scout their fields and apply a preventative fungicide such as chlorothalonil, mancozeb or Polyram. If the disease spreads north to Virginia, be prepared to apply a more targeted fungicide.
