Downy mildew was confirmed on cucumber on the eastern shore of Maryland last week. No new reports of downy mildew have been received. However, continue to spray cucumber with downy mildew specific materials and spray other cucurbits with protectant fungicides. Most importantly, scout the fields aggressively for symptoms.
