What is wrong with my Burr Oak?

Hanna City, IL

Hello All,

Having difficulty identifying the cause of the brown spots on the leaves of the young burr oak in the picture. Any help with disease/infestation identification would be much appreciated.

Hello,

After some research, I believe it's is Tubakia leaf spot. It's a form of leaf spot that burr oaks get. Please see this information:

And please see this for the control, which has to be applied next spring if you choose to take action:

With some love, it seems your tree will be fine.
