Active Plant Disease Alerts
AgAlert! Cucumber Downy Mildew and Anthracnose
Cucumber downy mildew (CDM) has now been reported from neighboring states (Virginia, Pennsylvania, Ohio and Kentucky). It is predicted that the disease can be in West Virginia, especially in the counties bordering other states, within a few days (https://cdm.ipmpipe.org/).
This is the best time to take preventative measures against this deadly disease. If cucumber plants are treated with either mancozeb (Manzate, Dithane, Penncozeb, Fore, Roper, etc.) or chlorothalonil (Bravo, Daconil, Fungonil, etc.) on a weekly basis prior to the arrival of the pathogen in your area, it can be effective in delaying the onset of the disease or completely preventing infections.
If you see or suspect a new plant disease outbreak that's not currently reported here, please contact Mahfuz Rahman with the WVU Plant Diagnostic Clinic or your local county Extension agent, immediately.
