***** Disease Update - 5 September ***** Two more sources of downy mildew have been reported. Gerald Holmes reports a serious outbreak on winter squash in Lenoir County in eastern NC. This has occurred in test plots at the Cunningham Research Center. He also states that it should be safe to assume that downy mildew is widespread in the NC coastal plains. Users should refer to the Eastern NC forecast for details. Dan Egel informs us that a moderately serious outbreak of DM is occurring on research plots in Knox County, IN near the town of Vincennes. Infections on pumpkins have been present for at least a week. This source is being added to the forecasts.
