Downy Mildew on symptoms on a cucumber leaf. Image from Inga Meadows, NC State.
Water-soaked lesions on the undersides of leaves were observed with signs of the pathogen — gray to black spores on the underside of the leaf. Very light yellow spots or lesions were observed on the upper sides of leaves. At the moment, downy mildew has not been observed on any other cucurbit in western NC.
