Removed that tree(first post) last year.
Here is another tree. I believe both have/had nectria canker.
Is there anything at all labeled to treat this?
I thot Phospho jet might stand a chance(small) of helping....maybe..
"Nectria canker produces large lesions on the magnolia tree's branches and trunk. The cankers eventually spread to girdle the entire branch or trunk of the tree, which eventually results in its death. The fungus afflicts trees in the spring and fall. Branches and stems stricken with Nectria canker will wilt or fail to produce foliage. Prune any areas that show signs of canker and dispose of the branch. Quickly eliminating the diseased areas and helping the tree to regain its health will often halt the spread of the canker."
Or maybe someone has another opinion...??
