FORECAST SUMMARY: Wednesday, July 30:
***** Disease Update - 30 July ***** Blue mold is spreading throughout the Ohio Valley. Numerous reports of blue mold have been received in the past week to 10 days. Some infections are weeks old but have only been recently discovered, while other infections are new. Disease activity levels vary. In general, the strongest activity is occurring from the Lake Cumberland area in south-central KY northward through northern KY and southeast IN. A second trajectory starting point has been added along the IN / KY border at Madison, IN. 36 counties in KY now report blue mold.... 4 in southeast IN... 3 in southern OH... and 4 in central TN. Recent weather has been favorable for disease development in the Ohio Valley. There is still significant potential for blue mold development in this region. Our thanks to Bill Nesmith in Kentucky for his excellent reporting and updates.
