Honey on Oak Root

[treeseer]

Jon, there is variability in advice from pathologists. That extension bulletin is typical in the US; it was the same in NC before I took Independent Study with my old path. prof. and reviewed Schwarze's Fungal Strategies book. That didn't change things enough, but it showed me how backward the US is in ecological matters in general.

 

Pathologists from Bartlett Labs have taught their field guys to treat Armillaria-infected trees with Trichoderma. When dealing with your client's trees, you might look to that more than to an extension guy who spends about .oo1% of his time with arboriculture. His primary audience is nurserymen, so his advice does not fit arboriculture. Though it can make a speedy sale for Basil Kutz.

I thought I'd share this study on the affects of temperature on A. mellea in invitro settings with you guys.

 

I found it somewhat astonishing that heat at 39 degrees Celsius was lethal to the fungus, at least in an invitro setting.

Interesting read (well, quick scan through) Jon, surprised that Trichoderma was being studied as a bio antagonist way back in the seventies. Had thought the more recent studies on the species were relatively novel.

 

Guess this wheel just keeps on turning.

Yeah, the first thing that went through my simplistic mind after reading the study?

 

Visions of portable generators powering electric blankets wrapped about an infected tree's base and roots for 72 hrs!

 

But like Tony says, a bit unrealistic!
