Cucumber Downy Mildew (CDM) has been confirmed on cucumber plants in our sentinel plot in Waynesville, NC (Haywood County). Approximately 50% of the plants were infected, but at a low severity (~5% leaf area is affected). Leaves showed symptoms typical of CDM: angular, chlorotic or yellow lesions on the upper surface of the leaves with gray to black spores on the underside of the leaf.
