Blue mold was confirmed Monday, July 14 in Washington County, VA near the town of Glade Spring at the Southwest VA Agricultural Research and Extension Center. Approximately 40% of a 4.5 acre field of burley tobacco is showing symptoms. Lesions were found scattered through this approx. 2-acre area; there were as many as 30 lesions on 6-8 leaves on some plants. Active sporulation is occurring. The worse symptoms were observed in a block of late-planted tobacco (June 11) which is now about knee-high. It is uncertain when symptoms first appeared. Other nearby plots are being checked for disease. The tobacco at the research station will be sprayed as soon as possible. Our thanks to Chuck Johnson for this report.
