FORECAST DISCUSSION: Monday, June 28: *** Blue Mold Update *** Tom Melton reports that blue mold has now been discovered in Pender and Robeson Counties in southeast NC. Heavy sporulation is present in some areas. There are now six counties in that region with reported blue mold. Steve Bost in Tennesssee indicates there are three more confirmed cases of blue mold. One is an active field source in Montgomery County. Another is an active greenhouse source discovered last week in adjoining Robertson County. The third is a field source resulting from transplants taken from the Robertson County greenhouse. The greenhouse plants have since been destroyed.
