Downy Mildew on Watermelon and Pumpkin

Kate Everts, Vegetable Pathologist, University of Delaware and University of Maryland; keverts@umd.edu

Downy mildew has been confirmed on watermelon in Wicomico County and pumpkin in Wicomico and Sussex counties this past week. All watermelon and pumpkin fields on the shore are at risk and should be treated for downy mildew. This disease is very aggressive on both hosts.
