Sugar maple - interveinal necrosis with little chlorosis

[ATH]

Looked at sugar maple trees that had necrotic tissue between the veins...but there was very little yellowing. Normally when I see this pattern (far more often on Red maple), the is almost no green tissue left - very chlorotic.

Thoughts?



It has been VERY wet here (and I know we are by no means alone!) - so wet that less than 10% of the fields are planted and today was the cut off for corn to be planted for crop insurance...

Found this article, but with no pics: https://www.canr.msu.edu/news/maple_scorch_wilting_and_dieback_remain_a_mystery

Yeah...sugar maple decline has been discussed far and wide for a few years now.

Wet can explain a lot in your situation though.

I'm not ready to call it decline...tree seems to be in good shape. I'll be back on the property in 2 weeks or so and will see if there has been any progression or leaf drop.

I know, just seen many decline over the years here.

Don't think this is the problem I am seeing...but have you seen this about Sugar maple decline?

She spoke at the ODNR-Forestry Forest Health meeting this past spring...

Is that possibly a symptom of V wilt?

That’s funny, y’all are loosing your sugars because it’s too wet?, and we are loosing our bigleafz because it’s too dry

Heat and pollution have also been mentioned I believe.

It can be, yes but looking for streaking is far better diagnostically

Not like i have seen...but not saying it can't be. I didn't slice open a twig because i wasn't looking for verticillium. I'll have a peek when I am back on that property.

What about anthracnose?

ancthracnose usually is more "blobby" - less patterned. I've seen some publications that show it following the veins, but not between the veins. Again, not saying it can't be, but not like I have seen.

Not for the OP but maple decline has been discussed for 50 years or so. Lots out there beside these but applies to more native plants as well.
