Definitely herbicide damage. Culprit was left on the scene. Awaiting confirmation from USDA labs who are taking their sweet time with things. What's your guess on the tree?
Neither of those. Finally got the lab report back today after a month of waiting. UGA had to send it to a USDA lab that took their sweet time. Positive for Mohave. Lawn guy was using it for weeds in the mulch beds. Killed most of the oaks on the property. Homeowner is wondering g if they will come back. Don't think so.
Idiot landscapers use it on paver drives and walks without knowing what "soil mobile systemic herbicide and soil sterilant" really means. Thats assuming someone actually read the label...
