Spinosad works on the kind I have (the kind that curl up like a snake) and leaves the beneficials that don't eat the leaves, unless you kill them on contact with it perhaps. Just make sure not to spray when bees are out, and you might cut off any open blooms to be sure. It's toxic to bees until it's dried completely. If the leaf-cutter bees are active, I'd not spray it because I'm afraid it would hurt them even when dry (?).
Squishing is best, but I had so many last year that they ate ALL of the foliage eventually on certain roses, even with my daily squishing. That's just too many!
I also found this interesting. It was a response on how to rejuvenate old rose plants:

I wouldn't move it. What I would do in your case, is BEND very slowly some of the more flexible canes of the blanc double, over a period of a few weeks, and see if you can actually get part of a cane buried, especially an upper part that may have some active growth. If you make a wound in this actively growing part of the cane, like a diagonal cut in the region of a bud, and keep this cracked open, with gently bending pressure with your fingers, and if it is possible to bury this cracked part of the cane 3-4 inches below the soil line, it will sprout roots there. Start the cut closer to the root, and cut upwards in a shallow diagonal, about a third of the way through the cane - the best knife for this is a heavy duty utility knife like an Olfa H1. This is called layering, as opposed to "air layering" which is an adjacent thread in this propagation forum. Or if you're up to the more complicated "air layering" then go for it, as well. Next season, you will find strong new growth coming from the base, where you cracked the stem, and the basal buds will also send up nice canes. By using this method, you do not risk losing the bush due to transplant shock, you have increased the size of your stock, and you now have a young bush that you can devote your training methods. The time to cut out older branches would be in the spring, during spring pruning time, before the bush starts active growth. If you severely prune a bush during active growth, the result is a severe check on growth, which you do not want. Sativa.

I have two of these plants. Both took this winter rather hard and got pruned near to the ground. Last year was hard on them because we got a snowstorm and a freeze here in May. I don't know if you got clobbered in Oklahoma or not with a late freeze, but it didn't do anything any good here.
Fragrant Plum seems to do better in cooler weather, and I can see that because it has a variety called "Blue Nile" in its parentage, that may be why it doesn't care for the heat so much. Fragrant Plum is a pretty rose, but it doesn't always bloom a lot.
I can only make comments generally about standards--the first year or two the trunk is fairly vulnerable to sunburn until it builds up more bark--so if you have sunlight beating down, shade the trunk if you can the first couple of years.
The other thing, the standard always needs support--even when the trunk appears to have grown quite sturdy--a strong wind can still snap it off. Use a metal support rather than a wooden one--the wood supports tend to rot out long before you are ready to give up the standard, and they can be difficult to replace.
I have 'Brass Band' as a shrub. Great rose--somewhat slow to get going, but once established, a very striking plant.
Hope that is somewhat useful.
Here are some that I grow:
R. alabukensis
R. cantabrigiensis
R. foetida 'Persiana'
R. hugonis
R. primula
R. xanthina
And some species crosses:
Harison's Yellow
William's Double Yellow
You can see pictures of them, and others, on HelpMeFind.

Ive never asked a question seil or someone couldnt answer, thats why i come here to learn. I did keep trimming further and further but at a point i decided it was way more than i wanted and just stopped. Im no good with feeling positive about a cane being old or dead. The pith is white but the cambium is tan, not green.. or where there is green under the bark, it looks very dry. So i stopped cutting. I hope im not stuck with only those 4 new gangly canes from last summer...id never be able to train it back to its former glory. Fingers crossed in upstate :) thanks to all.
yes charleney, ive had great luck with this standard. I bundle the graft but have never dug it out. I wrap everything above dr huey.. and hes as green as can be right now.lol. this winter was just brutally cold up here in the mountains. Ill hope for the best . Even though its just a knockout , i really do love it. Say a little prayer for her !
Rosefolly,
Ooooh, enjoy your trip. There's less rain down the south of the country, between Dublin & Cork. I'm in the NW. Here the climate is similar to the PNW back home. We've lovely summers but they can be cool.
My brother in laws are major cyclists. They don't bat an eye at 100+ mile cycling journeys. My partner helps organise the only Cycling Show/Expo in Ireland. Email me if your coming during that time.

Great tips!
