I sprayed daylilies with some soap that is supose to help rust, honestly, I dont know how it works, but I have never, and I mean never, had such a sudden and huge outbreak, as I have on the plants I sprayed. Luckily it just seems to be on those fans tho, not spreading.
I've used the 3/1 organic soap and that did seem to kill rust, but it is necessary to check almost daily.
But it is a joke to growers using the fungicides you have to suit up to apply.
Some plants catch every rust spore that flies by and run with it.
Heavy nitrogen makes plant leaves more rust prone; raising the potash level a bit can help deflect rust.
Soil minerals in rock dusts and seaweed make plants stronger.
Having rust tolerant plants from the get-go helps too.
When temperature increases past the rust ideal zone, rust takes a break.
Rust likes cool and wet, but not freezing or hot.
