seilMI said:I have to agree with Rosemary. There's no sign of the hyper-thorniness of RRD, Nor are the canes larger than the ones they are stemming from. What ever this is I do not think it is RRD. Could be RoundUp or any herbicide damage. I would cut off the affected canes and see what grows back.
