Pete, when you mention it looks like BS but isn't...my Heirloom has BS badly but also some yellow leaves?? Not the veiny pattern type of yellow leaves.

Sometimes I'm not sure if it is BS unless it is a really obvious BS pattern. How can you decipher?

redsox, the blackspot spots are matte and roundish with fringy edges. On some non-HT roses the margins are more firm-edged but notchy, or else more diffuse and spidery than typical blackspots. Spot diseases other than blackspot have smoother, more definite outlines than blackspots, often more purplish color.

In mid and late season, some leaves will just turn mottled or yellow and die without a disease being involved.

I kept Double Delight for many years and found it no worse than average for blackspot.

Mandi: My Angle Face is open in the middle also. In
fact it's so open I only have about 5 leaves left on the whole plant. And they have bs on them.

John

"Angel Face" is presently defoliated from blackspot, and I hope it dies soon.
Luxrosa

There are only a very few of roses I have ever had any bs or pm on so long as I stay up with my spray routine.
Crystalline--BS very rarely and minor if not sprayed.
Smoky--BS my most fungal inclined by far-hard to keep clean.
Lagerfeld--BS when I first got it, but now is clean.
Nightingale--PM only when behind in spraying.
Stainless Steel--SP'd. This was a terrible rose for me.
Cheshire--An awful rose that got SP'd quick.
My Lagerfeld and Smoky had BS when I bought them but it was eradicated very quickly and it has never come back yet unless I get behind spraying which rarely happens. I really have very little BS or PM at all, and only if I get behind spraying. I usually have none whatsoever. My spray is a combination of Mancozeb mixed with a rotation of Funginex, Daconil, and Honor Guard. I rotate to try and ensure I don't end up with a resistant strain of blackspot to contend with.

As mentioned above, it all depends on where you live.

I lived in S. CA for 25 years and Angel Face was a delight. And so where others listed here.

But out of that Mediterranean climate, as Molineux says most roses BS.

Perhaps the new line of supposedly BS free roses introduced by Kordes recently may be the exception. I need to try some.

Not only does disease resistance/susceptibility depend on where you live, the rose in question, the particular circumstances surrounding that rose in your garden BUT also the particular circumstances dictated by a PARTICULAR SEASON, meaning what was the spring/summer/fall/winter like this year. It all varies. There is not a single rose I know of that at one time or another is not susceptible to BS. I agree with Olga, much easier to list the ones that RARELY get BS.

Barbara

I have 3 roses, I need to know, what to do for black spot...I am just starting out and would like to know.....please help if possible. What kind of spray, do I need to get and when to spray........

I can take Angel Face off my list. My DW SP'd it
last night. Thats the second and last time for
that one.

I get a VERY SHORT season - but ABSOLUTELY CLEAN roses and no insect pests. I'd take my situation any day! :) So y'all come move on up here!

bbinpa--

You should probably start a separate thread for your question. Or use the search function at the top of the page to locate the many threads that have been devoted to that subject.

(The short answer is: Bayer Advanced Garden Disease Control--every 2-4 weeks.)

: )

My absolute worst is Blaze, my climber. It's going bye-bye before next spring.

I think that the "depends" clause is always appropriate, but Angel Face seems to be very prone to B.S. no matter where you live. I loved mine but after the garden renovation and it came time to replace them I opted NOT to. Same with Rise N' Shine (minis), Regensberg (floribunda) and Amber Queen. I did keep my Magic Carousel as it's one of my most disease free roses, but I see that someone is having problems with it. So I guess it depends.....

Looks like Angel Face and Peace are winning. I have some
and I'm making a list. I will start spraying as soon as they get leaves next spring. I usually started when I saw the first BS. Not again. If that does't work I will use them as starter wood in my patio fireplace. Wonder how
they would work in the BBQ? Just a thought.

John

I'll mention Paul Shirville, sometimes described as disease resistant, but one of the worst for spotting that I've grown. With some roses, it depends on what races of blackspot are in your garden.

I treated problem roses (purple tiger and angelface) with a systemic ( 1/2 what they said to use) in early June and I have no blackspot at all. I Even angel face who came home with BS was sprayed once and treated has no BS.

I have never had any BS on Double Delight and she has not been treated.

All of my roses have great circulation and I do pay attention to watering early. I have 21 different varieties.

I completely STOPPED spraying, and have actually had better results. When I was spraying like crazy I was getting thrips, aphids up the wazzoo, powdery mildew... nightmare.

We've recently gotten a decent population of lynx spiders and they're doing a good job with aphid control.

I finally cut every thing waaaaay back because I was sick of the ugly leaves.

The Angel face I've been very careful with since it's so notorious for bad luck. To the degree of pinching back blooms and pulling everything that even came close to touching. It is a perfectly square bush with four main canes going out in quarters. (sheer luck of the bud eye) I prune every branch that even threatens to take a turn towards the inside of the plant.

I still get the rogue spotty leaf that has to be removed, but so far no full scale takeovers.

Angel face is a little diva, but so far has been worth it.

Right now my biggest headache is leaf cutter bees.

When I gardened up north and was diligent about spraying I could keep even Angel Face spot free. But I wasn't always religious about spraying. There were a handful of roses that spotted no matter WHAT I did: Single's Better, Miss Flippins, Rise n' Shine, Tropicana and Dublin. When I got lazy Sunsprite was one of the few modern roses I had that DIDN'T get spots. I'm seriously considering getting it again.

Down here I grow mostly old teas and chinas plus SDLM. Only Lady Hillingdon shows any signs of spots but they are few and far between and I manually remove them as they appear. It is wonderful not to bother with the one big chore I dreaded (spraying with fungicides) when I gardened in Wisconsin. :-)

Peggy, Sunsprite is one of those roses that is immune in some gardens and highly susceptible in others, depending on the races of blackspot present. Mine were immune for ten years and then suddenly terrible. Some others like that are Rio Samba, Baby Love, Hawkeye Belle, and Colette.

Mr. Lincoln is my worst. If I so much as think about skipping a spray, he breaks out. I've had quite good luck this year without spraying on Double Delight, Pope John Paul (both with only minor spotting), and Tropicana (100% clean). Abraham Darby was doing well w/o spraying, but has recently given up in a big way.

* Rise-N-Shine
* Any other miniature rose I've ever grown
* Paul Neyron
* Marie Pavie

On a more positive note, every antique china rose I've ever grown has been almost IMMUNE to blackspot in my garden. Your mileage may vary.

Randy

Dublin Bay, I believe your message was intended for ang 1947. And I agree. Ang 1947-start a new thread.

Barbara (bbinpa)

Oops! So sorry, Barbara (bbinpa). What can I plead except heat exhaustion in our 100 degree heat!

Or maybe it was temporary insanity. Or maybe I need to get my glasses checked.

At any rate, I'm redfaced, Barbara. My apologies.

Kate : (

Kate, no apology necessary.

Barbara

I would like to thank everyone for your input. It's clear that modern roses are not very resistant to blackspot without regular spraying. Thanks again your responses have been very helpful.

"It's clear that modern roses are not very resistant to blackspot without regular spraying."

I don't think that you can arrive to this conclusion from the various answers posted above.

There are several old garden roses that are very blackspot prone in my yard, worse than most moderns (Baronne Prevost, Rose de Recht, Comte de Chambord are just three examples) while I do grow several moderns that are clean and were never sprayed and even more modern roses that are clean most of the time but if and when they get blackspot they can handle it very well.

I don't know about rose classifications, so I don't know if this is considered a "modern" rose, but I had an awful, awful time with Blue Girl getting covered in Black Spot. (We ended up calling her the "Black & Blue Rose"!!) Grew her at 2 different houses and SP'd her both places and will never plant her again.

Blue girl definitely should be classified as modern rose.

Distant Drums, Heirloom, Purple Tiger, Intrigue, Tamora, the Prince, country Dancer, Denver's Dream, Gingersnap, lavender crystal, and hundreds more...

Mine was MR Lincoln as well. My problem rose has been a new Touch of Class I bought this year. It just seems to be a weak rose. Maybe I bought a Dud. Moonstone also seems to be getting alot of blackspot.

In my experience, every modern rose will blackspot in Florida if unsprayed. That said, a few of the worst offenders:

Paradise
Peace
Angel Face

Keep in mind that I spray religiously. All of these guys are clean right now. But I know that if I miss one week....BAM. No leaves.

Yes , I have Bs on Intrugue and Paradise even with spraying .

Golden Celebration, worst one in garden

Carla

There is one notable flaw in this so-called survey. What seems to be the BS leader for you, in your local environment may be entirely different for someone else. I think it will be very hard to nail something like this down, and am really amazed at how some people assume that roses grow and BS all the same everywhere in the country. It's what goes on in your garden, your own little world that is important, not what happens to a grower in California, who may grow a rose or two that I can't get here. I care about what happens in my garden. Let's get realistic about this, OK? It would be much better to ask us what are the top ten BS roses in our gardens.

Thank you for the reminder, roseman, to always check the gardening zone on posts. However, I still think lists like this are useful. There are some roses I would not have known to look at or avoid if I had not seen them on someone's list. But I never take just one person's word for most things I do. If I'm really interested in a mentioned rose, I'll also check HMF and probably google it to see what others have to say also. Just because a rose appears on someone's list doesn't mean that readers instantly become hypnotized zombies with no will power or independent judgment. These lists can be a helpful STARTING point, and I enjoy looking at the pros and cons that get covered by different posters.

Besides, if I asked only for info. from gardeners in my immediate region, I would probably get NO feedback. As far as I know, I am the only person posting from my immediate region.

Showbiz (It has had no leaves for weeks. It's history.)
Rosarium Uettersen (it's new this spring. Hopefully, it will get better with age.)
Sherry

I wondered why everyone was saying Peace had blackspot when it doesn't here. So I went out there and took a peek.

Well there are non-circular brown splotches on the leaves, which could be a particular strain of blackspot, but I don't find it as offensive as the black with yellow polka-dots, and so Peace gets to stay...

I cannot say I have a no-spray rose garden, because I use Bayer imidocloprid (sp?) systemic granules for insects. I confess I treated my dormant roses with bordeaux mix and dormant oil last winter. And twice this summer I have sprayed with Serenade (an organic fungal control containing a close relative of Bacillus thurigensis bacteria). But that is all.
All my roses have some blackspot. But none have completely defoliated. Most still look great. The Serenade seemed to make the BS worse at first, and then seemed to improved it, so I do not know whether the weather just changed, or that Serenade really helped. Truthfully, and unscientifically, cornmeal (chicken feed) within the dripline seems to help the most.
Here's my roses: Ripples, Trumpeter, Cherry Parfait, Francis Dubrueil, Morning Has Broken, Winter Sunset, Ducher, Duchesse de Brabant, Monsieur Tillier, Reine des Violettes, Belinda's Dream, Shreveport, Love, Tiffany, Gold Medal, Tineke, Charles de Gaulle, and Don Juan.
Don Juan and Charles de Gaulle have the worst cases of BS right now, followed by Morning Has Broken and Cherry Parfait. Still, only Charles de Gaulle is on the chopping block right now; not only because of BS. It has not thrived (thriven ?) this first year even though it is grafted, and the much-vaunted blooms seem too little to me for an HT. Heck, I'll probably give it a one-more-year chance. I might SP Reine this winter, but not for BS - she is just too shy a bloomer for me. May be Hybrid but only a Victorian used-buggy salesman would call it Perpetual!
Oh - best for blackspot resistance: Shreveport, Belinda's Dream, Duchesse de Brabant and Tineke. I love all four.

Anything lavender/purple--except Distant Drums in my garden! Apricots/oranges a close second-- except Livin' Easy and Easy Going. Yellows-- I've been lucky with Sunsprite and Baby Love, constantly picking yucky leaves off Peace. Golden Celebration hasn't been too bad. Oh! a good word for Marie Pavie, she's clean for me too. I have a new garden composed of the most resistant roses I could identify-- and it's a sea of pink and white roses! No surprise, huh?

In deference to roseman,the top ten BS roses in MY gardens in no particular order:
Purple Tiger
Intrigue
Angelface
Peace &Chicago Peace
Inkspots
Scentimental
Margaret Merrill
Disneyland
Misbehavin'
Kordes Perfecta
Regardless of what zone one is in, I do think many rose gardeners experience bs in a lot of the same roses if your region is bs prone. Just my 2c. ~bb

Purple Tiger
Intrigue
Heirloom
Distant Drums
Gingersnap
Route 66
Denver's Dream
The Prince

If I didn't spray I'd have to get rid of:

Double Delight
Peace
Ballerina
Don Juan
Barbra Streisand
Mr. Lincoln
Fragrant Cloud
Fabulous
Iceberg
QE
Golden Showers
All of my Austins.

I'd only be left with teas. Which wouldn't be terrible.

MDE Pierre Oger Bourbon

Worst of the lot, all of my modern roses can get blackspot, but im not in a heavy pressure areas like some, usually my entire first flush is clean, then it comes on in degrees, the listed bourbon above is by far the worst, though I dont grow nearly as many roses as some of you. She also is by far the worst attractor of bugs... Its a wonder why I keep her at all =)...

I do not spray, not out of defrence to our enviroment (which I probable should be) but becuase I have young children and they do not understand about chemicals, they get the concept not to eat plants, but when you tell them its ok to smell flowers, then all of a sudden tell them, NO you cant smell that one its too hard for them to grasp, its easier just to live with the blackspot for me... I am gradually starting to plant more Once bloomers for me though, they are much more resistent to blackspot than many of the modern roses... But again, My garden is clean for a month and half, its only when things get too dry and the humidity starts up in the latter half of summer.

Silverkelt

BTW Pierre Oger below it really is pretty flower despite everything else...

{{gwi:261175}}

I have a micro mini called Elginglo that gets blackspot. It's so cute to see all those dots on leaves smaller than most spots on the normal rose leaves

Angel Face and Peace. I still grow Angel Face because the flower and the fragrance is worth it, but I have such bad memories of peace, you couldn't pay me to grow it!

Scott

Rose foetida and the reason many of the yellows are such blackspot magnets, it's in their genes via rose foetida. There was just not enough antifungal in Wal-Mart or Lowe's to slow the blackspot on Soleil d'Or in my garden.

'Kordes Robusta'
all centifolia roses
'Roseraie de L'Haÿ'

Down here OGR's will defoliate completely--worst offenders are Bourbons Mme. Isaac Pereire, Mme. Pierre Oger, La Reine Victoria. (Maggie does much better than these). Even polyantha Little White Pet defoliates about 50% (the Fairy does better). The past president of the local rose club is frequently quoted as saying "all modern roses get blackspot. Period. YOU MUST SPRAY!"

Worst offender is Golden Celebration if not sprayed, although it is clean with spraying.
Tamora and its Sport Lovely Child, and The Black Prince, and Yolande D'Aragon get BS with spraying here in Chicagoland

I've been growing "Angel Face" in my gardens for 4 years now and have hardly any problem with Bs and it's very floriferous...truly varies from zone to zone...so please keep that in mind...I am a no-spray gardener...Jeanne
