Thank you, Maureen, for the suggestion. What lice shampoo do you use?
Do you suppose the flea and tick shampoo I use on my dogs would work on
irises and not hurt them?
I have decided that the pests are really mealy bugs, not scale at all,
but the remedies should work about the same.

Hi Francelle,
I battle scale insects on my indoor plants. The classic remedy is to
spray
with a 50% alcohol solution. However, I found that I needed to spray
once a
week for three or four weeks if I didn't catch the infestation early.
Then I found a better solution. I was using a solution of the lice
shampoo
for thrips and figured since I had it made up, I'd try it on the scale.
It
works like a charm -- even better than for thrips. Just put one
teaspoon
into one quart of lukewarm water and spray all the surfaces of the
leaves.
I only needed to spray once on my indoor plants.
Good luck.

Hello, Iris-talkers,
This year I have discovered a new parasitic pest in my irises. It is
some
kind of scale. The tiny, pink, soft bodied insects live in the hollow
part
of the leaves. They leave a white residue in the creases of the fans.
Inside the leaves they create a moist, dirty mess that can facilitate
rot.
Ants are always present when a clump is infested. I imagine they have
the
same simbiotic relationship that ants and aphids do.
I have been fighting this scale all summer. Not wanting to spray
liquids on
my irises in this heat, I first used a garden insect powder. It slowed
the
ants down for a very short time; then they were back and I'm not sure
the
scale ever left. Next I tried spraying with insecticidal soap, which
specifically states that it's for scale. That worked better in that it
can
penetrate the leaves and overcome the protective coating on the scale.
It
didn't faze that ants a bit. Every iris rhizome I'm digging is getting
a
bath in the Clorox solution, because that really seems to do them in.
Have any of you ever seen this problem? If so what do you do about it.?
