More than 500 infected climbing roses at the Four Season Resort (which have been removed)
At my house: lots of them in the past two years. All removed and trashed.
Varieties I can remember:
DUCHESS DE BRABANT
... a lot more and I don' remember
A neighbor: Pink Knock Out Roses (at least 20 of them). She just cut down the infected branches ... disease came back.
My neighbor had 20 roses all infected badly. I know she buys only at Home Depot and Lowe's, while I don't. She removed and trashed all her roses.
I know this is an old thread, but I wanted to add my experience from two different states.
