oak wilt cut off

Been here much more than a while

Detroit, Mi.
I have been down in North Carolina for the last month. I have a few oaks that I was not able to get to before I left. I will be back in Detroit on the 12th of March. Would I be pushing it to prune those oaks then? I wouldn't be so concerned normally but this winter has seemed awefully warm and Maybe because I am in North Carolina and spring is in full effect I am thinking about calling off those jobs. None of them are critical or hazardous. Yee northerners, what is your take on the oak pruning cut off date.
 
Can't speak for the north, although I miss it terribly.

Here it's a crapshoot. The dates are academic and they don't reflect reality but are in sync with the known vectors captured in small areas at certain times a few years back.

Because of limitations both fiscal and cultural, the insect targeted was the one who provided the spores needed to isolate wilt but hardline eliminated the potential vectors that weren't studied. Because they weren't, it's assumed that no other mobile vectors exist - such are the limitations of knowledge.

Rule of thumb in light of the many suspected transmission possibilities...anytme a bug hits your windshield there are vectors out there. One highly potential movement source is the wind, another mammalian movement, another are ants.

If there are no hazards as you speak of, I'd be of the mind to let it go this year. Just to err on the side of safety and good service.
 
now, if its cold now but in two weeks there will be bugs on the windshield, how long does it take for a tree to stop attracting insects to a wound?
 
I am intimately familiar with live oaks, the focus of our studies here, wish I could offer some advice on northern species. We know that two hours in daylight, with average humidity in warmer temps are sufficient for a cutting wound to become resistant to innoculation by sap-feeding beetles.
 
Oakwilt,

I would be interested to read anything that you are working on. I spent a bit of time with oak wilt in Wisconsin, I was looking at doing my Master's work on it. I am in New England now but still have an interest in the disease.

Thanks,

TMW
 
She's a nasty invader that's for sure. The losses in Wisc. and MN are historical, as are the ten's of thousands of expanding centers in Texas here.

However there are differing opinions on both the fungus, it's tragectories and it's physiology within the tree and also it's host's responses to infection.

I'd be happy to share some of our observations, many of them seemingly off-course from the current advocacies of detection, treatment and prevention. We dig deep here, to the point of connecting environmental changes affecting susceptability and outcome. Man made changes for the most part. With these, we feel, are the studies that aim toward effective management of the epidemic.

You maybe in New England but you are not outside the prediction models, or mutational abilities for wilt to infect every region where any of the species of quercus prosper, sorry to alert.
 
Of the the tens of millions dollars spent, the hundreds of thousands of trees treated in this manner, the years of limited research applied and countless opportunities to study the relationship of environmental changes or nutritional ammending...he's still a dandyman for Rainbow Tree Care Inc. pushing Alamo using the same tired techniques and trying to get rich off it (I say "trying" because of the loss of active interest..thus the article).

It's to me, a renewed sales effort to get Alamo-brand propocanzole back to the top after two other approved off-brand formulations are being pushed in Texas, nothing more, nothing less.

I don't bother spending time attending TCI events because it's akin to a trip to the Mall. That article confirms my beliefs.

Thanks for posting it however, I'm reminded (thru the pictures and hype) that I'm not a good treeman because I don't invest 150K in mini's and 3007 GMC trucks. My sprayer is 1940's era and my main componant supplier is a feed mill and the Cherokee Nation.

[/ QUOTE ]Reed, read p. 54 in that issue and see if you recognize Pink Floyd in there. It's blowing my mind that some contemporaries don't see it.

It's true the trade show is all about shopping, along with some climbing demos, and it's fun bouncing gear and practice ideas off of folks you run into on the floor. The rest of the Expo is about information. Few of the talks I've heard there were infomercials; presentations are made more by working arborists than researchers (and I think most researchers do good ethical science).

i'm looking at doing 2 talks there in November, one on restoration pruning and one on root pruning. No power equipment used or hawked, but if a hand tool mfr

wants to give me a tool to use in a photograph I may be persuaded.

If you want to go to Connecticut Nov 8-9, I'll give you a deal on sharing a room.
 
How about Appel & co's article in the ISA Journal? They seem to have some evidence at last to support painting cuts in oak wilt country. Whereas prior to now all I could find was a suggestion to paint "just in case." Now if we could just get some research on what is the most effective but least harmful wound dressing . . .
 
Neem oil mixed in with the bar oil...1 oz. per gallon. An effective deterrent for both rotting organisms and all insects, suspected or confirmed vectors.

Our own studies, burdon of proof is on the State to discount this method (I'm too ordinary a citizen to write a 1/4million $$ check to the Peterson Lab at A&M for validation).

The leather scabbards for handsaws are also treated for effective residual presense.

24 hour range. Sat up all night on more than a few occassions w/ loupe and flourescent lamps in the middle of some spooky infection centers to confirm it. Even placed captured Nitiduli on wounds, immediate evacuation.

Just my added two cent's worth.

[/ QUOTE ]Man a video of that would be gold. You don't need $250,000.00 to document your work, man, just a camera and a computer. Your light is blazing dude how long I ben tellin ya get it out from under that bushel and dispel some of this darkness out here!!

Tinkering and respecting life post-terminal illness...little things get my attention but still Guy, I talk loud but can't be in the same room with anything more than 4,5 people - that I know. Actually it's not easy being in ANY room with four walls and a ceiling. I totally screwed-up me acceptance speech therefore the residual benefits that come with the Conservation award which has a cascading effect in the years afterward, downward.

I'm not returning most phone calls, my customer base are the same folk year after year, and the formulae we tweeked in '97 was boosted by a chem firm run by hotshot Wash. attorneys. Disease work to pruning/removal ratio is 1:22 last couple years, fine by my standards (working on a bluewater exit from pending cultural doom).

Technologically, which is what you're suggesting, I'm neanderthal...cell phone yes but optics were pawned long ago. I go to hospitals to visit patients and come down with resistant biota.

Grad students could do well by assignment to my passenger seat, spending the day as my left hand and taking notes, but look at the institutions sponsoring them. I've tried believe me. Advocating simplicity doesn't bode well for the industry dependent on sales - or funding research that leads to sales.

When you get here in June for the pow-wow, we'll bang heads a bit and maybe you can inspire me as I need it? Got a story to tell ya that might relieve some of your anxiety on matters diebacks and epidemics, least as it relates to me.

Neem oil...botanical based tools to fix botanical problems. Not much extreme there or complicated as things appear to be necessary for.
 
Great idea. Seems like a good thing to do all the time really. Like doctors wash their hands before going in for surgery. Do you know of a good deal on Neem? I found some organic natural flea medicine for my cat the other day that was just neem oil. Wasnt cheap and I felt like a little bit of a sucker but it seems to have helped control the fleas for now.

Interesting that the normal flea medicine is imidacloprid. I guess there has been some success in useing neem for EAB and the wooly adelgid, consistancy in product has been the main problem. My understaning is that not all Neem is the same, which makes sense to me.

[/ QUOTE ]My view of the U's and the industry are not so bleak. Maybe I see them differently because I'm closer. If simplicity is presented right and passes review then it must be accepted.

Yeah we'll see what happens in June. Maybe you'll cure my interminable naivete'.
 
Didn't mean it to sound so gloomy, sorry - today is different from yesterday, just frustrated at the choices one client made Saturday.

Got to get into this business thing, and my head out from under the clouds of seeing things too ecologically. A homesite that I spent a good day on, selecting which giants would stay and which would die went by the way of a D-9 Caterpiller, all trees gone when I drove by last night.

Building frenzy going on still, the elite that isn't affected by sub-prime mortgages or the price of fuel or war and things going full balls to live in the Hill country and an oak older than the nation is an impediment to the architect's chrome and black leather dreams of what a school girl should dress like and what kind of proposals a tree-hugging fish lover like me can conjure-up.

Think I'll just multiply my treatment prices up by 2,000percent...and they want showmanship, I'll act gay and wear a beret, ride a pink Vespa to work and be taken seriously for a change, this how it works?

Today's better...rain but chainsaw work 'til the chickens come home.

That's gotta hurt, triple if you weren't paid for your consulting.

I'll bet a pound of sugar in the D-9 tank would sweeten the process. Nah, I didn't say that.
