Notes on Downy Mildews – Cucurbits and Basil

Downy mildew on cantaloupe

Downy mildew has been reported in several Northern Ohio counties: on cucumbers in Huron, Medina, Sandusky, Seneca, and Wayne counties, and also on cantaloupe in Sandusky County. There have been also several reports of bacterial diseases in cucumbers (angular leaf spot) and pumpkins (bacterial spot) – these diseases can be mistaken for downy mildew. You can find information on cucurbit downy mildew management in my post here.
