They might come back next year if the problem isn't root rot. Does your problem extend to the protocanes than grew this year?

It does not look like it but to be honest I dont know which are which...It does seem like just a segment are dying..There are others that seem to be doing ok and are starting to produce. I am just waiting to see what happens with them.

Thanks

It could be raspberry cane borer. Do you know how to identify the signs of this insect that leaves rings around canes and kills the top of them?

Could also be raspberry crown borers.
