FORECAST SUMMARY: Monday, May 14:
*** Disease Update - 11 May *** We have a blue mold report from NC. Tom Melton reports that blue mold was discovered in a field in southern Nash County, near the town of Bailey. Infected plants were scattered near adjacent corners of two small fields. No sporulation was observed and the grower will apply Acrobat immediately. This is very weak source. Since the reports from eastern Wake, southern Franklin, and now southern Nash Counties are so close to one another (within 20 miles), we will continue to use Rolesville as a launch point for the forecast trajectories.
*** Moderate Threat for central NC on Tuesday; Low Threat otherwise *** High pressure governs the weather over the southern U.S. on Monday and Tuesday. Sunny, dry weather is expected for most areas both days. The lone exception will occur on Tuesday, when a front will form over northern sections of the Southeast. Skies will be cloudy in much of NC, with a chance of showers Tuesday and Tuesday night. Low Risk for all commercial crops on Monday. On Tuesday, Moderate Risk for central NC; Low Risk for all other areas.

***** 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. Please consult the Extension Service personnel in your area if you have concerns about these matters! *****
