Orange Rust on Heritage Raspberries

Posted by rosalinda Z5b/6a NY (My Page) on

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

RE: Orange Rust on Heritage Raspberries

Be certain to remove *all* affected plant debris. Don't wait.

Excerpt from management info from Oregon State University:
Cultural control
- Scout for the disease during summer.
- Quickly remove and destroy infected plants.
- Establish new plantings from a clean source or from tissue-cultured plants.

Chemical control
- None will cure existing infections.
