A Newsletter for Commercial Potato and Vegetable Growers Prepared by the University of Wisconsin Madison Vegetable Research and Extension Specialists
I write to share that cucumber downy mildew has been confirmed in Hancock, WI. Please see the attached newsletter for more information on management. Because this is on cucumber (so far only known host crop), I suspect that this is Clade 2 and I recommend use of the fungicides listed below for best prevention.
Please contact me if you have questions or concerns regarding this disease.
