Thousand Canker Disease

[TreeFellar]

Hey, I just wanted to spread the word about Thousand Canker Disease. It is a fungal disease that kills primarily Black Walnut(Juglans Nigra). I just wanted to see if a lot of people on here are having to deal with this. I'm sorry if this has already been a thread. Post your opinions/concerns/experiences in relation to TCD.

We have this in Oregon in the Willamette valley. some huge trees are starting to go... freaking me out.

There has been a ban on moving hardwood firewood in Bucks County Pa, because the disease was found.. No one knows where it came from.. Guess its just a matter of time before it gets out to everywhere... Scary stuff!

That is some fast-moving stuff! "Researchers report that the disease may be suppressed by soil applications of imidacloprid if they are applied before the disease has become well established in the tree;"

Time to schedule preventives?

so it has an insect vector?

The insect that carries the disease is called the Walnut Twig Beetle according to the Colorado State University's PDF file on the disease.

Dr. Jenny Juzwik of my research unit is pretty engaged in TCD research. A couple of links are below:

I wouldn't think that an insecticide would prevent the disease from being transmitted. The beetles will have to consume the treated tissue to be killed and by then the fungal disease would be transmitted.
I've asked several pathologists if they knew if Arbotect was being looked at as a preventative treatment as it is with Dutch Elm Disease. You could certainly incorporate an insecticide with this but it seems to me that it's the fungus that kills the tree and thats what you want to stop.

I've seen it work on Walnuts here. Very serious threat folks.
