SBR was first detected in the continental United States in the fall
of 2004 in a soybean field near Baton Rouge, LA (60,68). The
disease was observed in eight additional southern states in subsequent
weeks (58). These detections followed the inland track of
Hurricane Ivan, which made landfall on 16 September 2004 near
Gulf Shores, AL. P. pachyrhizi may have been transported to the
United States from the Caribbean or South America in this tropical
weather system
