Disease on walnut tree

Posted by nettleknit (My Page) on

Have recently bought a house and discovered what we believe are several walnut trees on the property. Most of them look ok, however at least two have dead sections (no leaves or anything) with black lumpy stuff growing on the branches. (no idea if that is what caused those parts to die or if it happened after) I haven't had any luck figuring out what this is, or what we should do about it. I'm guessing we should cut out the dead parts? The other parts of the tree look healthy with lots of nuts, so I'd like to try and keep them that way. Any thoughts?
thanks!

It would help us to help you if you posted pictures of the tree as a whole, the dead sections and a close-up of the "black lumpy stuff." Need to zero the sights in a bit because there are a lot of walnut problems from which to choose, and a close view of the problems can help.
Assuming you are refering to black walnut, Juglans nigra. If the "BLS" is occuring on otherwise healthy wood, there is a problem. If the "BLS" is occuring on the dead portions as you say, less worry.
As to the pictures, Photobucket works well for me.
