FORECAST DISCUSSION: Monday, May 22: *** 19 May Disease Update *** Tom Melton in North Carolina provides the following information...... Blue mold is present in Moore, Lenoir, Johnston, Durham/Wake, and probably Beaufort Counties. The number of infected greenhouses in Lenoir County now totals 25. Beaufort County is a new report with few details available. All of the Johnston and Wake/Durham plants have been destroyed or replanted. All of the field cases of NC blue mold have been a result of putting infected plants in the field. Little sporulation has been observed with the field infections.
*** Active weather for Monday and Tuesday in the Mid-Atlantic and Southeast *** One front is moving through the coastal areas early today, and another will approach from the west on Monday night and Tuesday. Skies will be partly to mostly cloudy with a chance of showers or thunderstorms for some areas each day. On Monday.... morning and afternoon showers likely washed out the bulk of any airborne spores released from southern GA or northern FL. Strongly Moderate Risk for southern GA and northern FL. There is Moderate Risk for growers in northeast NC on Monday. Low Risk for other areas. On Tuesday.... sky conditions will be mixed and isolated to scattered showers are possible for many areas. Spores released from the known sources will generally be moving to the northeast. There is Moderate Risk for north-central and eastern NC, eastern VA, Maryland, southeast PA, and southern New England.

***** NOTE: These forecasts/outlooks only apply to disease development from airborne transport of spores!!! We do not have the capability to ascertain blue mold development by other means, such as transplanting of infected seedlings, nor will we attempt to do so.
