I have Oak Wilt. Had 3 tree companies out. Plan is to trench, remove lost causes, and inject potential 'savables' with Alamo.
Only Red oaks have succumed. The Burr oaks seem fine.

I was told:

1. Reds & Burrs don't root graft between the species. The only way the Burrs could get it is via beetles, etc.
2. 2 Companies say I don't have to inject the Burrs with Alamo. 1 Company wants to do it.
3. We are talking 3 Majestic-sized burrs & 1 smaller one. The cost is astronomical.

We are more than willing to sink alot of cash into saving our trees, but we are by no means wealthy. Estimated cost on the burrs alone is $1350.00. I just hate to toss away money needlessly and I don't know what to do here & who to listen to. I will NOT let money be the guide here. As I said, we are willing to do what it takes! I just don't want to get ripped off. Don't know if the burrs need Alamo or not. Don't know.

Because of the severe nature of Oak Wilt, I don't have much time to gather more estimates, opinions. I've tried searching the net & can't find specific advice on if I should inject the burrs or not. I'm going to call the Morton Arboretum Plant Clinic when they open for advice & also have an email to the U of I Plant Clinic.

If there are any knowledgeable tree people with Oak Wilt. I'd appreciate your advice on this matter. I have to make a quick decision here.
