There are two new reports of cucurbit downy mildew in locations north of us in Hamilton, Ontario and Holmes County, Ohio. These sites will be threatening eastern Ohio and western PA in the next few days. There have also been two more counties in NC infected. Growers need to stay alert. Delmarva is at minimal risk at the present time. Be sure to check the CDM ipm PIPE Website for more info http://cdm.ipmpipe.org/.
