Rust Fungus Disease on Shenandoah Switch Grass

At first I couldn't tell if this was rust on the switch grass or if it was just the Shenandoah variety turning red. Ok, it's obviously diseased with some type of rust fungus and that's probably why it was on sale in the $1 bin. However, after about a week I noticed these new shoots coming up on the sides. It's not a goner! I just need to let these shoots grow without getting infected themselves. I cut all the rusty leaves off and hopefully these new shoots won't catch it.

It doesn't look pretty, but if this thing grows in next year it will have saved be about $12.

Fungus disease called rust for obvious reasons growing on Shenandoah Switch Grass

New rust-free shoots are growing - I decided to cut everything else back to prevent the spread of the disease (hopefully) and these new shoots still have half a summer to grow
