It's relatively safe to prune large cuts sometime in mid-summer and
December/January. Those are the times the pathogen vector is alive and carrying
the oak wilt to open wounds.

To be completely safe, I would wait till winter. If you have oak wilt anywhere
within five miles of your house, wait, if you can. Small cuts which are poking
your eyes out when you mow or walk by can be made, but I'd clean the sequiturs
with lysed in between each cut regardless how small.

IMO

Check with Texas A&M for a positive answer.
