Hi Jacki, please describe your fungicide regimen. If you're okay with spraying weekly, none of your roses should have BS including Tropicana. Perhaps the product you're using is ineffective or perhaps your spray technique needs improvement.

Thanks cecily for your quick response. I may have mispoke (or mistyped in this case) I started the first of April to spray, but I did miss last week, and havent sprayed today so I have only sprayed a total of TWICE. Once with Ortho RosePride disease control, and once with Ferti-lome Systemic Fungicide. I know nothing about either product, just picked them up a couple of years ago when buying other roses. I don't even know the shelf life of those type products.

I mixed both according to the lable and sprayed the front and back of the leaves. I picked off all infected leaves and discarded. (hauled away from property)The only thing I did not do was sterilize my pruning shears with bleach. Frankly, until this very moment I completely forgot to do so. Now that I think about it I suppose I should sterize my gloves to? Awwww, i hate to bleach my pretty blue gloves! LOL

Your Tropicana did not cause the blackspot on the other roses. Blackspot spores are everywhere in the air around us. Either wet, humid, or both conditions will cause the spores to germinate. Once it becomes established it's difficult to control.
Your Ferti-lome product contains the same active ingredient as Banner Maxx, a very good preventative if used regularly. Unfortunately it will not kill existing blackspot.
Go on-line to a rose speciality place such as Rosemania or see if a local garden center carries Mancozeb or Manzate. These products will kill/cure blackspot although the spots will remain. Spraying every three days for three intervals should have your blackspot under control. After that get a good preventative fungicide such as Banner Maxx, Funginex, Immunox, Clearys 3336, Bayer Disease Control, Compass, or Daconil, and use regularly as directed all season long beginning at leaf out. Follow your sanitation procedure regarding fallen diseased leaves.
Sterlizing your pruners will not stop the spread of blackspot. It's not spread by the tranfer of sap from one infected bush to another. I'd not worry about the gloves spreading the disease either. Remember the spores are all around us.
If your Tropicana is healthy otherwise, you shouldn't have to shovel prune it.

Just to add my 2 cents' worth. I agree with the advice above. I have no experience with Compass, though I here great things. But you may experience some sticker shock with some of the on-line products. I can say in the case of Banner Max, I bought a pint years ago for $70 and still have most of it. It lasts almost forever, because you only use 1/3 teaspoon per gallon of water and use it only bi-weekly for maintenance prevention. Works great for prevention. I agree with Karl about Manzate for curative power. And its fairly cheap. The only down sides are that it washes off in rain and leaves an obvious visible residue on leaves.
My recommendation if you're battling existing severe batch of blackspot is to use Bayer Disease Control (tebuconozole is the active ingredient). It can be purchased at Lowe's Garden Centers. I've never seen it at Home Depot or Walmart, though those places sell Bayer All-In-One with the same active ingredient. It's worth it to go to Lowe's and seek out the Disease Control formulation because it will last you much longer for the same money, and because the insecticides and fertilizer in the All-In-One are overkill. I've managed to chemical burn my roses from using that on top of other fertilizer I already had on the roses. Oops.

The Immunox and Ortho (Triforine) mentioned are fine products, but they have to be used twice as frequently for the same effect and in the case of Ortho is more toxic. Plus, Bayer has some curative power that the other two don't. It's not only preventive.

The only other advice that comes to mind is to watch your sprayers closely as you use it. Make sure the spray stays well-atomized as you spray. I use a cheap simple pump sprayer, and I find the tip often clogs slightly as I use it --probably because I seldom thoroughly rinse it out when I'm don using it. Anyway, Turning the spray adjust knob as I spray keeps it clear and keeps the force and pressure of the spray more or less where I want it. You want to make sure to get good coverage, of course.

OK, I'm done stating the obvious. Good luck with that sentimental Tropicana. It certainly is an eye-catching color and strongly fragrant. I had a Peace rose years ago that I initially thought was a hopeless blackspot magnet, but with changes in my spray routine after the first couple years, I never had a significant problem again. Cheers!

The Fertilome fungicide has the same active ingredient as BannerMaxx, so you don't have to run out to get another systemic fungicide. But, you will have to apply the Fertilome on a regular basis, every 10 - 14 days.

Thank you all so much for your assistance. I'm going to try very hard to fight this this year. We have had such heavy rainfall this year I'm sure that has contributed to it.

I really appreciate those of you who took the time to respond! I sprayed yesterday and will keep a keen eye on things.
