Bulldog is most likely on the money.These are extremely tough bushes and don't get "sick easily so either too much (as in too frequent) watering/rain combined with poor drainage would be my first suspicion. This would lead to things like chlorosis.
Since it is one branch it may also be spider mites or "age" setting in. Sometimes the bush will seem to need more sever cutting back before it will send up new and stronger shoots and there are no other explanantions but "age." If age is the case, pruning the branch right down to the base of the bush if you can will help encourage newer growth. If it is mites a miticide that is absorbed through the roots may help. While normally I would recommend products that are greener or organic to spray for mites the butterfly bush is a special case because you could wind up killing or making ill all the "good" insects, butterflies and hummingbirds attracted to the bush. "Systemics" like Bayer '3 in 1' or 2 in 1' or Bonide's 'Systemic Drench' will work by being absorbed through the roots into the leaves and chewing bugs like the mites will eat it there. Of the two choices mentioned Bonide would work better since the butterfly bush usually does not like heavy fertilization and fertilizer comes with the Bayer products. There are other systemics out there if you check with your local garden store.

I have a severe leaf yellowing problem on the old wood on my black raspberry canes. The new canes look healthy thus far. Should I use these same recommended treatments as the above poster or something else. They appear to be done fruiting this Spring. Since I only planted them in the early Spring I don't know that I'll get a second crop.

Have checked to see if you have Blackberry chlorotic ringspot virus or yellow vein?
I suspect you have a fungal infection that requires cultural and chemical teatment.
What you describe dosen't sound like an insect or nutrient problem
