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
We are more than willing to sink alot of cash into saving our trees,
but we are by no means wealthy and injecting the burrs. 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.
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
I posted this also on "forestry". Can anyone suggest a more
appropriate Google group to post this to? Thank you! I'm freeking
I dont have any advice, but where do you live?
I assume its somewhere in Illinois if you're contacting the UofI. I
didnt think Oak wilt was a big problem outside of California.
I just had a huge Oak die a few years ago. I went and counted tree
rings on the stump and it was over 175 years old. At the time I
thought it was oak wilt but it took several years to die. at the time
I thought it just died of old age.
Come to think of it I see a lot of oak trees dead and dying in
So we have oak wilt, gypsy moths, asian longhorn beetles, ash borers,
dutch elm disease, etc.. its a wonder that we have any forests left...

we do in Canada, and all serious problems are handled by them. Sudden
Oak Death and other serious diseases are dealt with( listed and advised
upon) through them.

I think that there are different diseases being confused here.
Sudden Oak Death is Phytophthora ramorum ( infecting tan oaks and black oaks in
Oak Root Fungus is Armillaria mellea
Oak Wilt is Ceratocystis fagacearum (mainly in the Middle west)

I hate to soundlike a doomsayer, but whoever is treating these trees
should have made it plain there are no guarantees. Once a red oak
show symptoms, it's unlikely to survive. Live oaks are more likely to
benefit from treatment after the signs have appeared.
Trearting the adjacent trees is more likely to make a difference. If
trees have been infected but haven't shown symptoms, you may avert
disaster by treatment (but still no guarantee). For trees that are
nearby but not infected, injections are preventative and, in that
capacity, temporary. Retreatment is probably a good idea, but you
might could get away with treating the trees that were closest to the
worst case. This is assuming you remove any trees and branches that
may die in a timely fashion. Once they're gone, the roots will harbor
the pathogen for awhile, and that's why you should treat the adjacent
trees (the disease spreads by root graft, if I haven't mentioned
that). But how long it will be a threat there is debateable, AFAIK.
I welcome any evidence to the contrary.
If you haven't looked at a third-party description of the problem, go
to the Texas A&M link:
You may also be able to find a similar link at a university or
extension office web site closer to you geographically.
