Yellow Rust on Raspberries

[banksy]

Hi all,

I have just come back from watering the plot, and whilst there I noticed what I believe is Yellow Rust on my newly(last November) planted raspberries... I think it is only on the summer fruiting plants, but cannot be sure as was in a hurry.

What can I do? Remove affected leaves?

Will the raspberry crop be affected?

This is our first full year on the plot and we were really looking forward to the raspberries more than anything else, if we lose all of our canes this will be devastating.  :(

Thanks in advance for any advice you can offer.
