[summer rose]

Hi everyone,
I was wondering if anyone out there can advise me as to what the problem of orange spots on my raspberry canes (leaves) could be and how I can best treat it.  I wonder if it could be a fungus of some sort and if so would a fungus spray be beneficial??

I have had it on my rasps for a few years now but still get good crops.
