Anyone recognize this. I would like to know if it is a disease or a bug. Trees have been in for 4 to 5 years. This is the first year I really noticed they did not leaf out allot this spring.The Maples have some skelentonising on the leafs that are there, but it starts as light color tracks. The Ash also has a thin canopy, and the leafs that are there are curled and brown tip. These trees are all on the same property, zone 4 Wisconsin, clay soil.

Kiss your Ash goodbye! If it doesn't already have the Emerald Ash Borer, it soon will. As for the maple, it's hard to tell from the picture.

Mike, the boar you refer to has had its ash seen 30 miles south of the Ill. /WI. boarder. That big pond between you and me has kept them out of our state so far. Here is another one of the Maples.

It's in the U.P. of Michigan. Nothing so far (in the last 10 years it's been here has stopped it) other than treating the tree yearly with Merit, which on a large scale, is cost prohibitive. Bozo's carrying firewood have hastened it's spread. Can you get a closer shot of the leaf??

We had similar problems on our nursery with the maples. Couldn't find a damn thing. Our nursery is about 50 miles south of our landscaping business...and about a month later it hit me that the nursery area had gotten two days of hail followed by extreme heat the next day. It poked holes, then burnt the crap out of them. (Not saying this is exactly what happened to you, but, we had the exact same problem with them last year)

This year, maples look perfectly fine. It's the lindens (and ash) I'm worrying about right now :cry:.

Here's a book that's helped me out quite a bit:

looks like anthracnose on the ash....

heres the wording from pirone's tree maintence: anthracnose brown spots occure over large areas of leaves, especially along the leaf veins. in wet seasons, infected leafs drop prematurely.

are there any twig problems or cankers anywhere on the ash?

I do not think its Anthracnose, found this paper and it does not fit my problem, unless I'am dealing with two differant problems. PR http://www.oznet.ksu.edu/path-ext/factSheets/Trees/Anthracnose%20Diseases%20of%20Shade%20Trees.asp
