Downy mildew on cucumber continues to spread in North Carolina and is now present in Ohio. There was a new report of downy mildew from Virginia Beach, VA this week. Although the winds are blowing this way, spore survival is not likely and the risk of downy today, Thursday, is low. Be sure to check the forecast at the CDM ipmPIPE website http://cdm.ipmpipe.org for Friday and the weekend.
