Hello, 

Thanks for reaching out! I have a few questions based on the photos you sent: 

1. Have you noticed any impact to the fruit? (is it shriveled? is it any different color? are there any rotten spots?)

2. Do you notice any symptoms on the bark? Perhaps oozing drops found along the infected branches, or is the bark cracked or peeling? 

3. It is difficult to tell exactly from the photos -- do you notice any spots on the green leaves? 

Thank you for getting back to me. I'm attaching a couple more photos that I'm hoping will clear things up. No oozing of the bark - it seems to start at the end of the branch and goes in.

Thanks for the pictures.  Your tree most likely has fire blight.  It can be difficult to treat.  It is usually not recommended to prune at this stage because it can spread the disease.  However you can mark the branches for pruning in the dormant season/winter.  It is also important to remove all leaves and fruit and fallen branches in the fall.  Compare what you are seeing with the following websites.

Well, heck. I think it's fire blight, also.Thank you, I appreciate the help!

You are welcome.  Good luck.
