FORECAST DISCUSSION: Friday, June 9: *** Blue mold has been reported in Tennessee *** Darrell Hensley reports that a field source of blue mold has been discovered in Grainger County in eastern TN, near the town of Rutledge. Lesions are fresh with active sporulation. Some systemic lesions are present also. This is moderate strength source. In addition, disease samples were brought in this morning from Sevier County, and it appears that blue mold may be present in that area. A new source is being added for Rutledge, TN. The southernmost of the three sources in southern GA / northern FL, Alachua, is being dropped. The remaining trajetory sites in south-central and southeast GA will represent any airborne spores coming from this region.
*** The 2000 bluemold county disease map is now available. Follow the link below or from our Homepage ***
*** Disease Update from NC *** Tom Melton informs us that blue mold has now been reported from 14 counties in eastern NC. Heavy sporulation is present in some cases. All counties in eastern NC have probably been exposed.
*** The weather in the Southeast, the southern Appalachian Mountains, and the lower mid-Atlantic states will be unfavorable for disease development this weekend. *** A broad area of high pressure at the surface and in the upper levels of the atmosphere will control the weather for the next 3 days. Skies will be sunny to partly cloudy and no rain is expected near the known sources or along the forecast pathways. All sources are Low Threats Friday through Sunday, with Low Risk to growers. Dry, hot weather is expected to persist through Tuesday.

***** 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.
