It was announced earlier today that  Southern corn rust is wide spread in the Coastal Plain of Georgia at this time.  This is very early in the year for an outbreak.   Spraying a fungicide to prevent Southern rust may be a little premature at this time, but consider the amount of acreage you may have to cover.  You may be need to start early to be timely.  Please consult the Ag Chem Manual for rates and fungicides.   We have a good crop at this point that needs to be protected from Southern rust.  So at the very least check your equipment and be prepared to make a fungicide application.  The current status of Southern  rust in the U.S. can found at http://sbr.ipmpipe.org/cgi-bin/sbr/public.cgi.
