Northern Ohio counties are falling like dominoes to cucumber downy mildew. The disease was detected today in our sentinel plot on the OSU North Central Agricultural Experiment Station in Fremont, Sandusky County. This is the sixth county in northern Ohio for which we have confirmed reports of cucumber downy mildew. Management information can be found in yesterday’s post and previous posts on this site.
