It causes necrotic spots on the cane near the base of the petiole attachment.[3] Raspberry spur blight can cause a significant reduction in yield, fruit blight, premature leaf drop, and weak bud and cane growth. The magnitude of damage is not clearly understood in the United States, however, studies from Scotland suggest damage to the cane itself is limited.[4] The disease has minor economic impacts by reducing leaves in the summer or killing buds. Major economic damage occurs if the disease manages to kill the entire cane.[3] In the United States, this disease is found in Oregon and Washington.[5]
