What kind of spray do you have?
virginiarose said: You said before that you rotate your sprays and you have picked out three different kinds, right?
I use 3 kinds---- 2 systemic and 1 contact

I assumed if it does not say it is susceptible then it must be ok, but maybe not. Maybe it means they do not know! LOL.
Either hybridizers spray everything on a regular schedule and don't now the plants have rust or they don't have the right conditions for a plant to show rust. To my knowledge only 2 actually say anything about rust on their sites. I may be wrong so I apologize in advance but I only remember 2. I have bought from rust free gardens in the north and as soon as it gets to my climate it breaks out. Now these are not their plants and they initially bought them somewhere else, but rust can lay in wait until the right circumstances are there for it to show up. The plant was not here long enough to have gotten it here before it broke out so I know it had it already.
Since it is the end of the season you could cut those plants all the way back and then spray them with what you have. The rust lives in any visible green on the plant so if you feel comfortable cutting it way down then you could cut it all the way down to about 2-3 inches ( where the fan starts turning white near the base).
