Daylilydude, folks are going to need a bit more information. If you could describe the 'rust' in a bit more detail, that might be helpful. And where are you seeing the problem -- on the tops or bottoms of leaves (or both)? Is it concentrated towards the base/bottom of the plant, mainly on the top leaves of the plant, or pretty much spread throughout?

Also, have you looked at the tomato problem solver yet? That might be a good place to start in trying to narrow your problem down.

More likely than not, your problem is fungal. But it could also be bacterial.
