I have a customer who has this in her tree and it is dying off quick. It is a silver maple about 30 - 35 ft tall. Can anyone tell me what it is?

Wow. it looks bad. At first, I thought it looked like Anthracnose, in which you would be fine in time, but this looks much worse. Do some research and don't waste time.

anthracnose is also what I thought at first, but am not sure. Most of the leaves are turning the black color in the pic and falling off, but the two small ones have that creamy pink looking fungus on the back, so does that raise the possibilty of 2 diseases or different stages of the same one? What is best to do with anthracnose? Will it come out of it? It is spreading pretty fast.

Bump...........:confused:

Patience... It generally takes more than 25 minutes to elicit a lucid, informative answer to such a question as yours... myself, I've got no friggin' clue...

I belive it is ANTHRACNOSE. It is a fungus.

You need only post once. I answered that I thought it was anthracnose also. Let it go and you might loose the tree. My moms S/O had it in his silver map Last year. we caught it in time but the tree still has not made a decent come back. reduced storage for the winter months will kill the tree.

I get the same thing with my ouarge trees. It's a leaf miner I believe? They feed between the leaf and make zig zag lines ever where. Spray the tree with insect killer,that takes care of mine. If thats what it is?

Could be a fungus? Spray it with liquid copper and mix in the insect killer.

Chimmygew.

Looked up possable diseases for silver maple in "diseases of trees and shrubs" by sinclair, lyon, johnson and I believe it is Anthracnose. This disease happens in cooler wet springs. It will NOT kill the tree, just looks bad. Here in New Jersey we see this a LOT in Sycamore and Ash. I am Mauget certified, and I use Fungisol Microinjection per companys recommendations, in September right before leaves begin to turn their fall colors. The Fungicide is now in the tree, and when spring comes, the fungicide is in the leaf to protect from this disease. I am getting 2 years control, from each treatment.

But before you consider any treatment, you must take some of those leaves to your counties Cooperative Extension Office to confirm, this is indeed the problem. Also pricing info in case you are not certified to do microinjections. Here it's about $20 per inch DBH (dia Breast Height) + stop fee. You may just want to have an expert make the application properly, as placement of the feeder tubes is key. OR the "old way" of spraying the tree every year when leaves are almost fully expanded. I find microinjection to be better IMO.

Get the Diagnosis first...don't panic.

Can you take some better pics? Those are difficult to see right. It could be quite a few different problems. Not Leaf miner . I don't see Anthracnose there either.

A quickie diag. w/o a magnifier is Anthracnose. If you've got the gear, do a foliar treatment. Your application is curative at this point and injection will take far too long to get an immediate benefit. Sorry if this opinion annoys anyone. Injections are good for trees in public areas or too tall to hit with a spray.

Thanks to everyone who helped. I told the customer that I believed it was anthracnose as you all have suggested. I am not certified to treat trees, only lawns, so I put her in touch with a nursery in hopes they could help her find someone to treat the problem.
