- Cucurbit downy mildew has been reported cucumber as far north as Maryland (Carolina Co.) on the Delmarva Peninsula. This is the first report of CDM in the region this growing season. All cucumber growers are encouraged to scout their fields on a regular basis. To track the progress of CDM in the US please visit the CDMpipe forecasting website here.
- There have been no reports of late blight in the region to date. Phytophthora nicotianae was reported on potato on the eastern shore of Virginia last week. Symptoms caused by P. nicotianae look similar to late blight. If you suspect late blight on potato or tomato please contact your county Extension office.
