Hi Folks,
I seem to have orange rust spots on some of my ripening red raspberry fruits. I don't see any spots on any of the Heritage leaves, just the fruit, and only on the ripe fruit. Any ideas?

I did some research, but haven't been able to find any info. I would appreciate suggestions for treatment whilst keeping it organic.

I am planning on cutting down all the canes once the plants go dormant as I prefer a big fall crop.

Thanks,
Rosalinda
