My chicago peace rose has black spot. I have removed the leaves but the canes are almost bare. Should i prune the bush back or not. Will new leaves come back before it blooms again

Remove and clean up all diseased leaves and remove diseased canes where possible.
Rake and discard all fallen leaves because they are the main source of spores in the spring. Also prune and discard any obviously infected canes. Several fungicides are effective protectants against infection. Spray every 1-2 weeks depending on the weather with: Cleary's 3336, Funginex, Kocide, or Zyban.
Sure, new leaves will come back before it bloom again

From rosarians I know - the best thing to do it prune it way down - about 1 ft. from the ground - remove all the infected leave (rake them up). The rose will bounce back with new vigor.
