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

Downy mildew was confirmed on cucumber in Sussex County, Delaware this week. It was also confirmed on cucumber in the New Castle County CDM sentinel plot in Newark on Friday, June 22.  Continue with a good preventative program. The hotter weather is not as conducive to disease development.
