Once I find soybean rust in one of my fields, do I need to be worried about spreading it to other fields while scouting?

When soybean rust moves into an area, it is possible that not all fields will initially be infected. It will not hurt to take extra precautions when moving from potentially infected fields to fields of undetermined infection. However, the amount of spores carried in person will be negligible compared to those in the air. – Daren Mueller
