What you are seeing is called Rust, it doesn't hurt the plant, it just make the leaves turn yellow. You can use Bayer 3 in 1 spray to kill it, but you must keep spraying every time you see it show up. It is very common is high humidity areas.
There are commercial product to help prevent Rust, Bayleton 50 and Strike 50 by Bayer are a couple of the better ones.
