I noticed that, They seem pretty close together. It always bothers me doing a tight line of holes on a stressed tree.

I took down some red oaks where they did Arbotech on dead ones. The wood was stained blue t months later.

I agree completely. Very limited storage with all the discolored (dead) wood and to get any blockage of access to carbs prob added to the straw that broke the camel's back.
 
Wouldnt know an injection site if it bit me on the derriere. I understand the issue of close grouping though.

Could you edit the photo and mark the sites?

Or is it the dark dots on the basal flare immediately below the nozzle of the blower?

It is the discolored (again...dead tissue) specks through the sapwood (light colored wood on the perimeter). Couple of them just above his hand on the blower. If you still need me to circle some I will.
 
they just cut some huge elms down in Suffield CT.

end of 2009.i believe they were the third largest in the state.that is what i was told by the locals anyway.

You can see them in the heartwood too, you get a cylindrical discoloration above and below the injection site, I've done a few huge trees and like to use a higher water ratio, and have added some nutrients. I was testing the seaweed sauce, highly dilute, around ten years ago. Uptake was good, but i was not able to follow the trees.
 
Here is an interesting read on the subject of DED and injections...

http://na.fs.fed.us/spfo/pubs/misc/ded/ded.htm

There are risks to tree health in injecting trees. A long-term preventive injection program may cause significant stem damage to a valuable elm. Consider whether early detection (and thus opportunity for therapeutic treatment) is likely for a high value elm. Consider whether bark beetle and DED fungal populations are high in the surrounding area. As with any resource management decision, it is important to weigh the risks against the benefits.

I like the recurrent theme of "management plan", so many forgett that you cannot just do the macrofusion, you need a watering plan and probably soil remediation. The latter is much more then just dumping wood chips around the base of the tree
