This Asian pear tree was on the property when I bought it, zone 8B; not sure of the variety, the fruit has thin smooth yellow skin with very faint brownish dots, overall smooth texture.

The bark on the trunk looks like it's in poor condition, but may be normal?  Does anyone know if it is diseased or normal?

The rest of the tree looks healthy. It’s not uncommon for trees to start looking like this after a few years. I don’t see any deep fissures or weeping sap. Nor do I see any borer holes. We haven’t had any deep freezes that could injure the tree. I’m no arborists so I could be wrong.

I think this is anthracnose canker.  I get this pretty often in asian pear, certain other pear varieties, and in Betch rootstocks.  One way I've treated it before is to bury the affected area or put a tube around the trunk and fill with soil.  This seems to help a lot -- I don't know a magic spray for it but will follow to see if someone else does.

This will usually doom the tree as years go by - any branch or trunk that gets ringed will soon die.  It is also pretty infectous over a 2-4 foot reach.
