As far as I know, they have retired.... don't know if someone else has the business. I found them easy to contact and was really happy with their service..... perhaps you have tried to contact them since they retired.... it is too bad they are gone! I tried to propagate Island pearl from cuttings.... in a very slap happy fashion, and so far one is all that is left!
I know this is an older post, but thought I would respond anyway. I just bought an Island Pearl Rose from Milner Gardens. They have an ongoing plant sale of unique, high-quality plants.

seil, how long was your Actinovate trial, and did you start before blackspot appeared?
The one Actinovate label that I found listed mildew but not blackspot for roses.

I had a JFK that I shovel pruned after 4 years. it was always soooo promising. excelent growth, long canes, no black spot (only mildew when the damp ocean air sticks around too long), and HUGE HUGE HUGE flower buds which never opened all the way because I think it is too moist and/or cool so close to the ocean.
I gave up and swore off white roses. :)
Follow the dead cane downward and you will find something wrong near the base. It is broken, or has been bored hollow by an insect larva, or the bark has been girdled by a canker fungus (patch of black or brownish bark). Cut the dead cane out.

I had this happen on my Baby Blanket rose tree a few years ago. Do what Michael suggests and find the point where there's some kind of injury and cut it off below that. It took a year or so to fill back out but my tree recovered just fine afterwards.
I did go to helpmefind, but everyone on their list seems to be out of this rose at this time...
Thank you deervssteve, I'll try rosesofyesterday...
I really wouldn't want anything shipped until Fall, so will keep my eye out for this rose, it sounds great for our area!
Oops...here he is.

I used the edit function. Hopefully it should work now.

The leaves show some minor early infection of blackspot. They also have some whitefly damage and it looks like a rose slug larvae may also have been chewing on some of the leaves. None of it terribly serious.
You should have just left the foilage on the plant as even damaged leaves still provide energy to the rose. It will shed them itself when the leaf is no longer viable.
Those are really pretty flowers. Some rose bushes hold their flowers longer than others, and this one may be just a bush that lets its flowers go pretty quick after they open.
The only thing to do now is wait and see how it does after losing so many leaves. I think it will come back, but keep an eye on it for new growth. Keep it watered, how much depends on whether it is in direct sun or not and your daily temps. Roses do best in direct sun.
Not sure about that wire holding it up. If it's an important wire, you might want to get a narrow trellis to support the bush and get it away from the wire.
Good luck.
All the Knock Out roses are "shrub" roses--they grow about 4 ft tall and 3.5 ft wide--but depending on what region you live in (and which Knock Out rose you select) they might be bigger or smaller than that.
About all you need to do with Knock Out roses is dig a nice hole--(you can mix some humus in, if you wish), plant it about the same depth it is in the nursery container, and water in well--as in very, very well. There--now you are ready to go. If the weather gets dry, water it--otherwise let nature water it.
Don't worry about feeding it the first couple months, or even for the first growing season. Next spring, feed it with something like Rose-Tone (or Plant-Tone).
You might want to put a couple inches of mulch around it, keeping it back several inches from the main stem.
Now, enjoy the bright color Knock Out brings to the garden.

In my z4 area, I plant grafted roses with the bud union (graft point between the root stock & the above ground branches) 3-4" underground. Own root roses, which is how Morden Sunrise is usually sold, I planted 1-2" deeper than the soil depth in the pot they came in.
Thank you, Henry. I was also told by a nursery that I should prune my roses to avoid the disease. He said that it takes more time for the mite to travel inside the rose than they previously had thought, and it usually enters high on the rose since it floats in the wind. I good deterrent is to prune hard in the winter.
I appreciate your links on this disease, and am pleased that the site here in Oklahoma, at least, is asking for samples to be tested.

What's your general location & growning zone?
Are you sure they are dead?
A pic would really help us...
Were they big or small Ko's?
Maybe rabbits ate them?
Our young knockouts were eaten to ground last winter but look great now...
