Continental epidemics of downy mildew plant diseases spread across the Carribean, Latin America, the United States and Canada each year. Fungal sporangiospores produced in infected fields are transported via the atmospheric boundary layer to distant healthy crops. The North American Plant Disease Forecast Center in Raleigh, NC provides farmers and the agricultural industry with timely documentation of new outbreaks. In addition, 48-hour geographic risk of further spread are issued daily for the pathogens Peronospora tabacina and Pseudoperonospora cubensis.
