More blue mold in Pennsylvania

Blue mold was found in late May in several traditional outdoor plantbeds and also some greenhouse float beds and was carried to several fields.  Since then, the disease has spread to additional fields in at least two counties--Lancaster and Chester--and some fields now have significant sporulating populations. "Most farmers are now aggressively spraying," says Jeff Graybill, Pa. Extension agronomy educator. "It seems to be worse on the burley types but is present at some level on Pennsylvania seedleaf and Southern Maryland as well."
