Sounds like whiteflies. They are tiny, almost like a bit of lint, and fly
off en masse when disturbed. I squish them like aphids.

So far, no need to spray insecticides, and am expecting the Japanese Beetle
invasion any day now. I did set down some Milky Spore, and maybe the bt will
have an effect too, perhaps? I take a daily walk through the rose beds, and
squish any colonies of sphids I might find, and sprinkle a bit of Sevin dust
as needed, and I figure that'll deter the whiteflies as well.

Nope! Not white or small enough!

I know about MIlky Spore, but can you tell me more about BT?

Does Sevin kill JBs? I know it can be used on edibles, so I imagine it
is not too terribly toxic, or at least not as bad as my standby
Orthenex.

Like aphids, only more mobile. Funny, I've never heard of them
attacking roses. They like tomato plants though.

Whiteflies are easy-beats, Shiva. Anything systemic will wipe them out.

What you originally described didn't sound like whitefly to me but if
that's what you have, they are more of a nusance than anything and
should be killed by your Orthenex. Sevin will work on them, too. There
are also some more enviro-friendly controls:

Yes, Sevin (carbaryl) does kill Japanese Beetles and is often the
recommended insecticide for them. But remember that it is not a
systemic - it is not absorbed by the plant. Beetles (and other
insects) have to ingest it directly off the leaves (or absorb it through
direct contact (i.e. be present when you spray so they get hit with
it). Anything more than a light rain will wash much of it off. It is
not nearly as toxic to vertebrates as Orthenex (WARNING - handle
according to the directions on the label!).

Here's Cornell's profile of carbaryl:
http://pmep.cce.cornell.edu/profiles...baryl-ext.html

Also, it will do damage to Boston Ivy, Virginia Creeper and Maidenhair
Ferns and early in the season to Virginia and Sand Pines so if you have
any of those around, use extra care.

Because the name Sevin is a registered trademark, you'll have to look at
the active ingredient of insecticides to see it this is what they use.
Ortho, for instance, has carbaryl packaged under the name "Bug-B-Gon (R)
Lawn & Soil Insect Killer with Grub Control" but other Bug-B-Gon (R)
products use other active ingredients (Esfenvalerate or Permethrin
mostly). Again, read the entire label of whatever you buy.

Just as soon as I sprayed today it rained--and the sky was not even

to rain every day this week EXCEPT today.

I was surprised to see Sevin mentioned here, because it was one of the

Well, now I wonder if that is what I have. They cluster around the
base of the bud or just below, very snowy white, look like lint.

Aha! Now then, we just need a systemic that will work if applied
while it is raining, and work while it is raining, until it is applied
once again in the rain! Arrgghh! At least the JBs are soggy and
miserable.

The first thing that came to mind is a woolly psyllid which is a sort of
cicada like insect but much smaller. They are jumpers and have a white,
cottony, powdery substance on them. there are also a few woolly aphids
(Paraprociphilus or Prociphilus species). Whitefly don't so much jump
as take wing and fly. Psyllids jump somewhat like leafhoppers (although
they fly after jumping). It's hard to tell by a short description so if
you've found pictures that look like what you have, I'll let it go at
that. Whitefly have a white powdery substance on them but nothing like
what these others have. Not what I'd describe as "snowy fuzz."

I hate it when that happens. We've gone a week without rain here
(although it rained 20 minutes from here last Friday). The roses are
enjoying life, actually. Auguste Renoir is having its second flush.
When you consider that NOT ONE BLOOM opened on the first flush, you'll
understand how much that means. Pat Austin and Johann Strauss are
getting ready, Linda Campbell is putting on lots of growth which means
the flowers are coming. Of course, there's plenty of black spot to go
around. Sprayed Saturday. Will again this weekend (weather permitting).

Sevin will work on them, too.

Well, I suppose it is worse than some things, better than others. Must
have been before I started reading the newsgroup. I'll do a Google
search and see what was said.

Yeah, me too. These are all designed to kill things. They are all
toxic to a greater or lesser extent to humans. Precautions are warranted.

We've got some whiteflies as well here in San Jose. They seem to like the
tomato and zucchini plants, far more then they like the roses. Spray
pesticide doesn't work very well, because they tend to hide on the underside
of the leafs.

I agree - they can really hit a tomato bush but I've never seen these
things take to roses.

That depends on the spray. A systemic one will enter the plant and
poison the sap, making the insects drink their own death. You CAN use
those sprays on food crops although I'd personally rather not do that.
On roses, systemic is the way to go.

I have a few whiteflies around my Madame Hardy; for some reason they only
like her. I spray them with a hose and that seems to dissuade them from
making themselves permanently at home.

It's an odd season for bugs. This morning I found a tomato hornworm
lolling drunkenly on a fuschia branch. It was a large worm too, about
four inches long. I had no idea they liked fuschias, nor did I see any
evidence of how it got there (it wasn't there for long; I persuaded it to
take a little walk with me to the trash dumpster). I'm hoping it doesn't
have friends who like roses.

A neighbor moved and insisted that I take a bottle of some dry
fertilizer/systemic combo. I'm not into feeding with dry fertilizers and
haven't ever used systemics; this one had a primary ingredient of
disulfoton.

From googling through rgr the relevant wisdom seems to be that disulfoton
has a noxious scent and that the concoction, if used as directed, can't
have much of an effect systemically because not enough of it can be used
in combo with fertilizer and it won't protect new growth. I'm disinclined
to use liquid sprays other than milder things like insecticidal soap, but
the thought occurred to me: is there perhaps a granular systemic that can
be used alone, without fertilizer, reasonably effectively, or is the
liquid route the only solution, so to speak?

IIRC, there are two problems with granular systemic pesticides. One is that
the pesticide does much more damage to the enviroinment when applied to the
soil than as a spray. There is a greater chance of runoff into the water souce
and at a higher concentration. And it's deadly to the living things in the
soil, i.e. earthworms. Second, plants are not able to take up enough of the
ingredient to be truly effective.

I bought a container of that stuff at the same time I bought my first roses.
It's still sitting in the shed. Next time we make a run to the dump I need to
drop it off at the toxic waste station. I don't expect I'll ever use it again.
