Knockout Roses--is this Rose Rosette Disease?

6 years ago

Hello All,

I was just outside watering my knockout rose beds and noticed some rather strange growth on three different bushes. I have a sinking feeling that this is rose rosette disease, but before I go to the unfortunate task of digging them up, I want to be sure. Please note that each of these pictures are from different bushes and the weird looking/possible RRD areas are isolated to one single cane on each rose (except for the last picture.)

That being said, is there any way to salvage these if it is RRD and it is just on these single canes? It makes me sick to my stomach to think of having to dig these rather mature roses up.

Also please disregard the one photo with the copious Japanese beetle damage. Between rain and Japanese beetles, it has been one tough summer.

I'm really at a loss here and would appreciate any input anyone might have. Thank you in advance.
