Maple tree bark diesease

dariusf · 21st May 2009, 12:34 PM

Hi, we have a 1.5 year old Autumn maple tree that was doing fine last year. This year we see that while many new leaves came out, there is a big part of the center of the tree with branches with no trees. After closer investigation I can see many strange growth on the bark of the effected branches as well as the trunk. Searching the web I can't find anything like it. There are actually a couple types of growth or fungus on the bark. We are in Chicago suburbs. I have uploaded a few pictures to help with identification.

Maple

Thank you very much for your help
Regards
Darius

Looks like some sort of scale crap ... try hort oil (white oil).

The oil coats the buggers and they suffocate, gently hose off a few days after.

Just read the label on the stuff.

Thank you much for such a quick reply. Should I consider the effected leafless benches as dead and cut them off or is there a chance they will still produce leafs? The few I trimmed, still looked alive inside.

Thank you
Darius

Not yet, some might resprout.

Just kill the bugs at this stage, it'll take a few months to see what lives and dies as far as the tree's canopy is concerned.

So these would be bugs under the growth spots? I was thinking it was bugs right under the thin layer of the bark.

Thank you

Hi, I have a product called Triple Action Plus from ferti-lome

it contains mostly Hydrophobic Extract of Neem Oil

Triple Action Plus : Ferti-lome

Would this do the trick?

Thank you

I did some more google and found a very informative page on scales. Perhaps it will help someone else.

Never questioned your wisdom

I guess the little white powder stuff in the 3rd picture was the hatched larvae or some other thing
