I found many leaves like this on an Azalea I have since 9
years
this is the first time I see such a stuff
could someone tell me what it is a how to cure it?
the leaves are dark green and specked with round paler
green dots ,
it is not chlorosis some stains are 1 mm diameters others 3
mm
diameters sometimes separated sometimes united in clusters
Thanks

It is hard to tell from that picture, Theo. As Alan says if you
can get a macro view of the leaves it will help.

If the leaves are DISTORTED (raised bumps, like blisters), you
may have azalea leaf gall. It is harmless. Just remove the
leaves.

Check the undersides. You may have scale. Use an alcohol-based
pyrethrin spray, or rub them off.

Or, it could simply be old leaves. Are they mostly INSIDE
leaves? If so, they're last year's spring crop and will just
fall off.

The link wouldn't work for me for some reason, but judging by
the
description it could possibly be azalea lace but.
Check under the leaves and if you see small "fly" type insects,
whose wings
look almost like lacework (and seethrough) that would be lace
bug.
If so you can spray with a systemic insecticide. I know Rogor
is one here in
Australia, you may have it over there. If not ask at a nursery.
Just watch
it as it is pretty potent to humans. The leaves will not
recover if it's
lace bug, and it may loose affected foliage, but it will come
back.
Good luck

That's rather drastic treatment for lacebug. A soap spray or a
pyrethrin spray (with or without soap) will do just as well and
at a lot less risk.

Well, whatever it is -- and I suspect it is a sucking insect
(whitefly, lacebug, etc.) damage -- you don't have a serious
infection. If you see the insects, spray them (soap, pyrethrin
or a combination). Otherwise, remove the leaves.

The leaves look very healthy, otherwise.

Yeah, maybe it is on a bonsai, drastic that is. Perhaps I should have typed
post a little better. The treatment I suggested will not hurt the plant, or
cause foliage to drop. The foliage will drop due to the lace bug. It's just
at work when our Azaleas are infected by lace bug the only treatment that
seems to work is rogor (or similar/equivalent). Our Azaleas may be unlucky
to get lace bug once a year max. The problem is we have used organic sprays,
and were actually a test area for them, and if you did not get the spray to
contact every bug reinfestation occured shortly after. Same happened with
the Aphids. Then again, being a bonsai, ie small, it would be a lot easier
to get all the bugs. Sorry, it wasn't something I thought of till now.
For the original poster it's not lace bug, as the second link worked for me
and I saw the bug. Looks to be a aphid. They could have caused the dots,
that I'm not sure about. Certainly the bug is not scale, as scale are
usually hidden under a coating of some sort (sometimes wax).
If you really want to go organic, and this will work, introduce predatory
wasps or the good ladybirds to get rid of them. You would have to buy them
from somewhere in your local area.

Good luck with it.
