What is this Disease on this Rose

Cher(6 SW OH)June 2, 2014

Posting a photo for a friend with a Double Knockout. Can you tell me what this disease is and is there any treatment? You can see the black and gouged stems and mega amounts of thorn in clusters. Maybe a spray, pruning, etc? Appreciate any advice. TIA
