Something Foreign on my Pecan Tree #817036

Asked November 29, 2022, 2:31 PM EST

While picking up pecans today I noticed that there is something foreign appearing around the trunk of the tree. It almost looks like mud but is appearing as high as three feet up the trunk. See pictures attached. What is it? Should I be alarmed, and how do I get rid of it? Thanks, Bruce Smith

Bruce, you appear to have Bacterial Wetwood or Slime Flux in your pecan tree.  I am attaching a link that will give you information concerning this disease.

Thank you so much for the information!

Other than cutting off a large branch that was damaged by the wind, I don't know of any additional stress the tree can be under.

I don't see any real action I should take at this time. Please confirm?

Thanks again,
Bruce Smith

Yes, no real action. The bacterium will take its course. The best recommendation is to keep the tree as healthy as possible and keep an eye on it for further weakening.
