Last week I reported that downy mildew on cucumber was confirmed in Dorchester County, MD. Since that time it has been found in Bridgeville, DE and Caroline County MD. Yesterday it was also reported in Salem County, New Jersey on cucumber. All cucumbers grown in Delaware are at risk and preventative fungicides should be applied.
