Branches on the back side of the tree have died in the past two years. It has pink flowers and red berries. It has nice leaves and flowers beautifully this spring. Another branch is affected and the leaves all turned orange at once without falling off. The remaining part of the branch changed in two days. The tree has many red uneffected berries including the dying branch. I have enclosed some photos. What disease does it have? Can it be saved? If not can I plant another ornamental crab in it's place? We have had the tree for about 15 years. A few leaves look like the one attached.

The pictures are not clear enough for me to determine the health of your tree. Please go to the following site and compare your leaves. Trees do not tolerate defoliation if it occurs year after year. http://www.extension.umn.edu/garden/diagnose/plant/deciduous/crabapple/leavesspots.html
