OK. I will get some. Now how would it go into my spray rotation. I normally use Bayer once a month and Honor Guard once a month leaving a two week interval between the two.
I do have some that have had sick leaves for a long time, but I have a new Quietness that I noticed this morning is starting to get the tiny yellow triangle at the tip. It hasn't got the ugly brown part yet. Until you had posted that it was a fungus I thought it was probably insects, due to the fact I was already using two types of fungicides.
Thanks for the info. It is always appreciated.
I haven't noticed the chevron symptom on Quietness. Maybe it is something else.
Remember, I'm not giving you a firm diagnosis. That would need to come from a path lab. Actually insects (leafhoppers) cause the chevrons on some plants by damaging the midrib on the underside. I have looked for this bite damage on rose leaflets and not seen it. Also suggestive of fungus is it being confined to certain varieties, usually tending to be glossy-leaved and blackspot-resistant.
I think you could tank-mix Daconil with the conazole fungicide if the weather is not extremely hot. Both are chemically rather stable.
Nice photos, Jacquie! I like the Liatris behind the roses. For me, in my zone 5 Nebraska garden, The Generous Gardener is a floppy biggish bush that might only be 4 feet high but the canes reach out 6-8 feet to the side for something to climb on. Mine happens to be at the bottom of an arch with real climbers behind it, so I tuck the canes of TGG into the arch to keep them out of the way but put them horizontal so it'll bloom more on laterals (hopefully). Mine is about 6 years old and at best it has maybe 2 or 3 flushes a year. It has quite notable winter dieback - the canes don't look cankered but are dark brown inside - and it's a bit slow to come back from regrowing. The pictures below are a section of the bush this week that show a fairly lackluster bloom cycle.
In a really mild winter like we had before 2013, and TGG had surviving cane, it did want to climb. Here it is on the arch looking white among a variety of other climbers (the white on the tripod in front of it isn't TGG - it's Crown Princess Margaretha). That's the best it's ever looked, as well as the biggest, and I don't think it rebloomed at all that year.
I think your plan to have a tripod over it sounds good given its growth habit. In most zone 5 years, it wouldn't cover an arch like the photo above, but it would appreciate something to hang on. It's a nice enough rose, but I would put it behind other roses so it can shine when it's nice and not be annoying when it just sits there.

Asclepias incarnata is the one that does well up here.
Diane... I was raised on a farm and the day was you could always see milkweed on the fence rows and ditches. Those days are gone. When I mentioned the farmer that was spraying. Later that night on the local news they mentioned the farmers were spraying a mix of liquid ammonium and a herbicide. Every house and yard in the block east of the field was getting hit with it.
It certainly won't do much good to plant it if they hit it with herbicides
I have never grown any, but have observed several climbing hybrid teas and other climbing sports of modern bush roses.. The general view is that most do not repeat as well as the better climbers and should be expected to give little or no repeat bloom. A further drawback that some have is blooming on long, 2-foot laterals that are good for cutting but look awkward on a climber. I hope someone can give information about the varieties you mention.
Haven't grown the climbing sports of Blue Girl or Tiffany - though I'd like to. Do grow Talisman, Climbing, the Western Rose Company 1930 sport of the HT. The current one's from Angel Gardens & only 2 years old. A previous one from Rogue Valley some years back perished from unintentional neglect when it was young & I was ill, but its beauty & fragrance prompted me to replace it. This one's given 2 flushes already this season at only 3' tall, so quite promising. http://www.helpmefind.com/rose/l.php?l=2.22066&tab=1
Same here as altorama. Lots of little sprouts, easy to pull up, that must have escaped from someone else's garden. They are a minor pain, but don't threaten anything. I have LOTS worse things to deal with. Like 101 today when things were starting to look a little better. Phooey. However in Jackie's case the year round mild climate may have created a mint monster (plus being ignored for years helped, too.) Diane
Thanks for the kind comments everyone. Holly, I just went outside to check scent and didn't smell all that much. If OR means own roots then no, mine is grafted. I posted an earlier photo of Mohave and was told the colors reminded her of a desert sunset when there is smoke in the air. I think that a neat description. Again, thanks everyone.
Wish newscasts would help. We've had at least one recently, but the two heart shaped knock out rose planting at LoveField airport are severely infected and have been so for about 2 years. No blooms this year, just the ugly diseased foliage and they just keep shearing them back. Similar plantings across the street became diseased and were removed. Not sure what the delay is in ripping them out. Here, it's an epidemic.
There are not many rose gardeners around, we need all the help we can get. Some newscasts might help to educate public. Someone from my rose club has RRD landed on the wild roses on his property (about half acre of wide roses). He couldn't take care of them by himself, called county, but got no help from them. I tried to get him to call the TV stations.
