Let it live! I see it often here as well but generally it is not visually affecting the crown.

 

[NickfromWI]

Removal isn't one of the options here. I Wouldn't even consider it! Tree only appears slightly chlorotic. Enough that a passing tree guy would notice, but not enough that some lady walking her dog would ever notice.

I'm wondering what treatments, if any, yall would apply

There has to be some sort of treatment.

 

[rskybiz]

In honesty this is more a ipm thing as much as I want to know all about it it really seems to be a whole field in and of itself. I might add that Guy seems to be on top of these things maybe he might chime in.

Clean the wounds, for starters. Remove all dead and infectious material, scrub and rinse with water, then rinse with hydrogen peroxide 1:1 with water, then cauterise wound with blowtorch.

"“Streaks can be stubborn. The 5X plan
is: Excavate, Expose, Examine, Excise, and
Extract. A hole within the streak suggests
insect infestation, no hole suggests disease
infection. Damage living tissue only if justified,
such as cutting out margins for disinfection
or analysis. Lesions can be treated
with trunk drenches, injections, and/or
cauterization. For risk, look first to the flare
and the forks. Improving tree health is a
universal treatment.”

After all those "E"'s I can only say one thing....Excellent.

Good info, Guy.

 

[rskybiz]

Thank you Guy😁

 

[MasterBlaster]

Damn straight.

Awesome post!

Beer for everyone!!!

 

[pantheraba]

Make mine a sweet tea.

...Lesions can be treated with trunk drenches, injections, ...

What types of solutions would you consider? I'm considering trunk injections of one of two products....

 

[sotc]

Agri-fos has worked well for us, and it's a trunk spray, not injection.

Pull a soil analysis, around here I've often found these to be nitrogen deficient.

 

[DMc]

Have you tested for Verticillium Wilt?

Pull a soil analysis, around here I've often found these to be nitrogen deficient.

Unless you have just fertilized, that will be the finding everywhere in most cases. Many labs will not even report on surface nitrogen due to its mobility and volatility. At a bio-ag symposium my wife attended, filled with crop consultants, it was advised by a keynote speaker to ignore all fertilizer recommendations but learn to interpret the soil analysis report for correct site requirements.

 

[sotc]

That's interesting, we've had pretty good results from our analyses. Magnolia has been about the only consistent tree to report low nitrogen.
Obviously you need to look at the report as a whole but what is the point if you ignore parts?

 

[sotc]

Simplot has been our tester fwiw. Not sure how they rate in that industry

 

[DMc]

..Obviously you need to look at the report as a whole but what is the point if you ignore parts?

My point was to read and understand the actual whole report to confirm what may be needed. The labs recommendations are often not accurate and they haven't a clue about what is best for trees.

 

[sotc]

I see, and agree. Often they make good recommendations but often too aggressive. I think mostly because they are used to dealing with annuals

 

[treelooker]

Nick just clean the gunk out and rinse, for starters.

+1 on using soil tests.
