Peronospora hyoscyami f.sp. tabacina is a plant pathogen infecting tobacco that causes blue mold. It is an oomycete (a fungus-like organism) that is highly destructive toward seed plants. It is very prevalent in humid farming zones, like the southeastern and eastern U.S., Canada, and countries bordering the Caribbean. The disease was first identified in 1921 in Florida and Georgia. Ten years later the same disease was found once again in the same region of the U.S. The disease began to spread into Virginia, Maryland, and North Carolina. A few years later, the disease reached Kentucky and Tennessee. In 1960, a blue mold epidemic spread in approximately eleven countries. There was approximately twenty five million dollars in losses which is nearly thirty percent of tobacco plants at the time

dbo:abstract
  • Der Tabakblauschimmel (Peronospora hyoscyami f. sp. tabacina, häufig auch noch unter dem Synonym Peronospora tabacina bekannt) ist eine Form der Falschen Mehltaue (Peronospora) und gilt als eine der wirtschaftlich bedeutendsten Krankheiten der Tabakpflanze. Der Eipilz stammt ursprünglich aus Nordamerika oder Australien und wurde interkontinental verschleppt, woraufhin er in den Jahren 1959 bis 1961 eine folgenreiche Epidemie in Europa und im Orient verursachte. Tabakblauschimmel ist in Deutschland und vielen anderen Ländern eine meldepflichtige Krankheit, die an den unteren Blättern beginnt und sich nach oben fortsetzt. Er braucht für seine Entwicklung eine hohe Feuchtigkeit und mittlere Temperaturen – wegen Resistenzgefahr wird die Wirksamkeit der eingesetzten Fungizide (z. B. Metalaxyl) in Deutschland überwacht.

Each year, Peronospora hyoscyami is introduced as blue mold as windblown spores from outside the region by infected transplants. (en)
