Currently there is no downy mildew reported in Delaware or Maryland, and sprays for this disease are not warranted. The risk in the region remains low. Downy mildew of cucumber was reported in North Carolina and Georgia this past week. For updates on where the disease has been reported and on which cucurbits, go to http://cdm.ipmpipe.org/
