Hi All...

If i didn't know better i'd say sooty mould from aphid "droppings" but it's
thr wrong time of year. These plants (4 to 5 feet) have been outside all
year and have sooty black deposits on the leaves. These deposits rub off
with a finger or thumb.

These Ilex Aquifolium are variagated, in pots and we're stumped...

any ideas for what it is and a control?

Thanks for any help... back to google /

Sounds like it indeed. Richard, you should have seen the scale insects
last year and now the mould is living on the honeydew they extracts.
Check this for confirmation. I have a similar problem with an acer.
Every year without fail, if I don't get rid of the scale insects,
everything below that tree is later covered of sooty mould.

Scale insect? Usually what you notice first is the black deposits.
Search for the scale insects under leaves *above* the area of black
deposit.

Even after all the rain over the winter? i thought any exudate from the
insects would have washed off by now...

i'll take a look at the link... thanks for the pointers all!

Bob, La Puce and K... Thank you..

Just been out to the yard (re-potting the prickly buggers as we speak...)
and discovered beautiful brown scale insects hiding under their waxy coats
underneath the leaves and above the sooty mould.

Now... La Puce's link mentioned Provado as a systemic control. Off to find
some (or similar as we're commercial and I still have a whole lot to learn,
as you can tell )

Intercept is the commercial form.

That's great Richard but don't quote me on using chemicals! I'm
totally organic!! I remove my scale insects with washing up liquid and
a tooth brush, or using the back of my gorgeous knife, a Nontron, the
oldest found French knife (but that's another story ;o)

Richard, we get our stuff from Syngenta, if it's of any help to you to look
up their web site.

Found something that deals with the blighters in the "poisons" cupboard. We
have not had to resort to chemicals up here for years!

21 5 foot Ilex Aquifolium may be difficult with a toothbrush ;o)

Thanks Rod (back on home PC now... hence name change..) Will try the gunk
we have on the next calm dry day. If not we will look for that one.. I
hate to use chemicals and wouldn't at home... But my boss is pretty good,
only using as the last resort.
