Old tree injections practice?

[Gary Prentice]

I think a member of AT, called Scottie, works for Bartletts and is involved in PHC. You could try to contact him.

 

Is this question to do with the Special Trees unit, on the L6?

[Mikula]

Could you give me the email of Bartletts, Scottie or whoever works there?

There has been a real resurgence in interest in the US in tree injection of systemic chemical treatments for pest and disease control. The Tree Care Industry Association (TCIA) of the US hosted a series of "Tree Injection Summits" across the country over the last year. Those sessions gave treatment developers and vendors a chance to interact with the community of arborists engaged in injection, or considering injection as a treatment tool. I was on all of the presentation programs to speak about my concerns about the response of trees to injection injury.

All of that being said, no one spoke of differences in large trees vs. small trees or old trees vs. young trees. We did speak of big differences with respect to tree vigor and amounts of available sapwood and the importance to inject under environmental conditions that favored good uptake and distribution of chemical treatments.

So I am somewhat cool towards systemic injection, but they can have a place as a legitimate treatment. Injection tools probably should not be the first tool out of the toolbox, though!

Sorry, it sounded like an assignment on the Level 6, Diploma in Arboriculture. Special trees is the unit/module on veteran type trees.

 

Don't know if this will work,

There has been...

Thank you for the concern. We'll take that into acount.

[Mikula]

Well, I'd like to add a note to my question.

 

What we actually need is somebody's experince in injecting OLD trees (> 60 cm in diameter). All right, age might be no difference. But there's been a lot of all kind of injections in the whole world so far, - probably, some of them were performed on OLD trees. I'm only looking for that experience published, nothing more.

[KTSmith]

Thanks for the additional detail. I reckon your interest is not so much historical but predictive to help guide current or near-future treatments.

That poses some challenges in that most big/old tree injections that I've worked on from the wound response perspective did not involve the currently available injection technology or chemical formulations. So it's hard to make "apples to apples" comparisons!

[Mikula]

Yes, our interest is now purely practical: we'd simply like to read of anyone doing the same (injecting old trees). We work mostly on old park trees, not on fruit ones. And injections - is a new topic for us. So we are looking for any experience of the kind published somewhere.
