Dwarf yellow apple tree diseased--HELP

[Addie]

Our 20 year old dwarf apple is very sick--can anyone tell me what this is? It doesn't exactly look like a rust
or fire blight. The diseased leaves are falling off the tree. There is fruit on the tree this year, actually it's
covered in 1-2" apples for the first time in years. Can anyone identify this & suggest treatment?
We planted this on our daughter's first birthday, I am sick at the thought of losing it. Thank you.

There are numerous viral and fungal diseases that have these same similar symptoms. All are very serious. You should get in touch with a local expert such as your county extension agent or an arborist who specializes in fruit trees. It would be a disservice to you to try to guess what is happening to your tree for a problem as serious as this appears to be.
