Hi folks.
Just back from 2.5 weeks in London and southern Italy...wonderful trip. Lots of family, etc.
Get back to find roses on our balcony (haven't gotten down to the garden yet) have some kind of
blight. There's a white powdery stuff on the new growth and a couple of little green hoppers in
residence. The specimen in the photo something called "Orange Drift".

This is on a balcony about 300 feet in the air. The young woman who was dog sitting did water these roses.
But that is all I know about the conditions in the last couple of weeks. Any ideas?

I'll also vote for aphids and spider mites ... but the aphids look like they might already be dead. I'd wash the daylights out of those roses with water.

I asked the ugly green thing to pose for me. Here is his (or her) overhead shot.

And here is a rather demure side shot.

Anybody recognize him or her? Do you recommend any lethal weapons? Vinegar? (White? Sherry? Malt?)

By the time I took the pictures and sent them on to you folks, my spouse had drenched the entire bush with something from Bonide.
Thanks, I'll let you know.

The white ones were already dead.

I would call that an aphid.

Which means that water could have disposed of it.
