areas are the entire State of Mississippi with the exception of Biloxi; 

 the entire State of Alabama except a small locality near Muscogee, 

 Fla. ; the entire State of Georgia except Grady County; and all parts 

 of Florida other than those indicated in figure 4.

 grown with safety. The two small infested areas in Alabama and
