While seedlings are less resistant to rust, probably not all (or any) would die from it.
I use Green Magic spray (4 oz to 1 gallon) and that works fine, and any new plant coming in that might be suspect
gets soaked for 2 minutes in this solution too.
On seedlings without a bunch of leaves even the 3 in 1 organic spray will slow rust down or even kill it off if spraying is kept up.
Bayer make a systemic spray that works fine too, and I sometimes use that in rotation.
