Hello All,

 

Can anybody tell me what is going on with an apple tree?

 

The trunk is about 2” in diameter and part way up the trunk there is a circular, black, sooty spot, 1 ½” in diameter, that appears wet in the center.  It also appears to have run sap at some time in the past.  I have not wiped off the sooty mark yet, but there appears to be no bark damage.

 

What would cause this injury?
