Ok, took my brugs into the IMP Homeowner Specialist at the U of GA here in Griffin. I was with her while she dissected it, and put in dishes to grow--she should know more Thursday.
She asked me questions, that I must ask you.
We looked for "SB" to no avail, in her books and on the web.
She did find a "wheat stem rot" with SB in the name.
Does anyone know the scientific name of SB?
What she sees is "Phytophthora" right now, does anyone know how this differs?
Edited to add:
Oopps! She also mentioned "Pythium".
Remember she's needing the scientific name of SB.

My visit to U of Ga Ag Dept
I think Phytophthora is right on.
I've seen it spelled differently too, stengle, stangle, stengel, stangel, la la la la la!
This is a good page too
http://ohioline.osu.edu/hyg-fact/3000/3116.html
This is from the German google search. Im sure Monika will be able to help also. I think what you did was great Vi!!!

Phytophthora and Pythium were not found in my plants. Phytophthora infestans causes a stem and foliage rot in tomatos and potatos.
Monika is there another word that might help us identify the bacteria that causes stangelbrand?
Sue, all I was told, that they have found a Fusarium spec. organism, which has not previously been found in Brugmansia before. Puzzling for all of us including the researchers was, that mainly yellow Multis were affected by it.
I keep coming back to Rye diseases when searching. Is it known to effect Rye crops in Germany? "Urocystis occulta" or stem smut in rye is one that came up.
Halmbruchkrankheiten look similar to SB. We had a excellent systemic fungicide I sprayed my plants with and also tried several other fungicides. None of them had any effect either in preventing or healing.
Thank God for you Monika!!!! Your hands on experience on having lived thru this infection is so valuable to us. We do not have to reinvent the wheel with our own trials and errors.
Wouldn't it be grand if our agri. dept. had a cure! LOL.
And regardless what Vi finds out, anyone who has it should bring their suspect plant to theirs. We have been talking about this resource on ABADS. It sure can't hurt and we may learn a lot about it!
I sent an e-mail to the horticulture expert at my county extension agency, hopefully he will be interested in seeing my infected plants (which seem to be happy as can be in their little plastic bags!) They do charge $40 to look at them, though-dang!
What?? Not in Georgia! Did you ask as a homeowner or a business? They asked me that question--but nothing about $$--shoot, I thought that's their job?
Maybe we can find Hummer_nut to answer this.
From what I could fine, stanglebrand is a kind of fusarium. I found that on a google search some time back. Fungicides are not effective against fusarium stem rot. It is a big problem with tomato, potato and pepper farmers. Some lose half their crops to it every year.
Phytophthora, Pythium, fusarium, are all listed as preventable and with "some curative action" in Cleary's 3336. I use this with SubdueMaxx as a drench as precaution, but ultimately I throw bad looking plants away. After everything that has transpired here in the last few days, and after talking with Susie tonight, you can definately say good-bye to all the Suaveolon genes I have here, except anything I have grown from a seed, and Gloria's last babies which will be quarentined till further growing prove healthy. Dr. Seuss which I have had forever and looks good will now multiply and be my early warning system so to speak. I am anxious to see what you find out VI, lets us know as soon as you can, and thanks!
For those of us who are not so knowledgable, could you please explaine a little more. What is Cleary's 3336, and how do you do a SubdueMax drench? I've looked at all of my cuttings and everything in the gh. All the trunks look fine, I do have some curled leaves. Have been fighting mites inside but things improve when I spray them down and move to gh where it is more humid and cooler. I do have some slug action going on out there and need to put out more slug killer.
Is there a list somewhere of Suaveolens'? I would like to see how many I have, and what Im tossing. I refuse to take any chance.
Cleary's and SubdueMaxx are both fungicides, both require a applicators license in MO and may where you are, but you should be able to obtain through your Ag-extension, it is usually free and you have to watch a video, even farmers have to have these for chemicals. A drench is just what it sounds like you drench (soak) the soil,with a solution based on the instructions with the chemical about mixing, I find that for small applications a hose-on adapter 1:16 works just fine, many people already use those for fertilzing at home. Frannie had a picture of one somewhere. I also do this if a stem breaks, or gets rubbed badly, just as a prevention. I really DO NOT think this will cure stangelbrand, but hopefully help prevent some disease. There is another fungicide Alice (Abutilon) was talking about the other day, hopefully she will buzz by here and give us the name again. I think Shirley has looked these up on line too, she may know where you can find them and the cost for smaller amounts. I think though Monika has the right idea of staying away from disease prone varieties. So when my plans come out this year from their winter sleep, many will not get to wake-up :(
Well, I for one just grew an incredible white suaveolens last year and I am keeping it! LOL
And if I were to get rid of aLL my Frosties, my yard would be naked!!!
Also one of my favorite blooms last year was Tropical Sunset.
SB is going to have to come here and drag them out screaming and kicking!
I will not give up my Suaves,first to bloom,last to bloom,and all in between.
I'd say we need to work on getting the SB weak genes out.IMHO.
I'm with you Root and Kell. I don't think I could live without Monster Brug as well as many others in my yard. Hope nothing bad happens to any of our brugs. That would be so devistating
I'd like a list of which ones are Suaveolens types also, so I can pay more attention to them.
Trouble is... there are many hybrids that have suaveolens genes in their history. The plant may look like an aurea or versicolor but might have a suaveolens grandparent. The disease can also infect non-suave plants if proper sanitation hasn't been followed.
okay, thanks PoppySue!
this is what it says on the Oregon State University extension service website:
"If you bring a sample of a diseased plant to a county office of the Oregon State University Extension Service....
The Master Gardeners or county horticulture agent will try to diagnose the problem. If it "stumps" them, they will send your specimen into the OSU Plant Disease Clinic, along with the information you provided. You will charged a fee (usually $40). Results are sent back to the local county office and an OSU Master Gardener volunteer will call you with the results."
I'd also have to take at least half a day off work to go there!!
Carena, maybe you could mail the plant directly to the OSU clinic. The fee still seems pretty steep to me.
http://plant-disease.ippc.orst.edu/clinic.cfm
Carena, do not worry! Others will bring theirs in I am sure. I would not miss work to do this unless I had a terrible attack of it.
Vi, I can't wait to hear what your AG department says. Though if it stumped the German experts, it must be a hard one!
Me too! I've been taking excerpts from this thread and emailing them to her. I also sent the nice write up you did on SB. (Hope that's ok)
She said it was the "most interesting case" she's had in awhile, I just hope she does see something growing to identify or pass along.
I will check out the Ag departments here tomorrow,I think this is the best route for us.
Sure Vi, I wrote that to help us all. I am going to post it here also in a little while. If we all learn how to recognize this, we will get control of it hopefully!
I know Monika said in Europe it came on with such force in 1995. It took a few years to figure out what was going on. She said lots of the brug fanciers would not talk about it openly, just whispers and that made it spread even faster. They did not want to admit they had it. At least here we are all talking about it and we are aware.
I just hope no one feels like they can't admit they have it or ask if they have it. We really need to track it and identify the carrier brugs if there are any.
I hope no one is defensive about it. If people act insulted when someone lets them know a cutting they gave out has SB, we will get nowhere! Please tell the giver, it will help protect their brug collection as well as others.
This is a time we really must act together for the sake of our brugs.
Well said, Kell.
lolol.. i have always been very open about mine... i have had everything somewhere, sometime.... the wilt, nematodes, mites, leaf fungus.....
I've lost a lot of brug cuttings this Winter, but I think the SB at my house that's causing the problem is me (Sylvia Ball). lol

Oh Sylvia -- you are too funny! I think its because you just didn't have a warm enough place to put them due to your DH... Did you get all your stuff planted???
hehehe, that was good Sylvia.
I still don't have it all planted. Our son came to visit for 4 days, and by the time he left Monday morning I was pooped. The weather yesterday, and so far today, has been yukky for planting, so most of them are still sitting on the covered patio looking a little tired of sitting there. lol
Sylvia! Too funny! It can be hard to over winter little cuttings. How it works for me is I keep them so dry so they do not rot. But sadly, I lost a few also.
Sylvia: I know its a terrible day outside, but one of the things I learned in my class is the best time to transplant plants is on a rainy/overcast day. Maybe if the wind will die down... I got some shrubs planted yesterday, but I'm still afraid of a frost to plant anything tender yet.
So, Gretchen, you are telling me to get off my bfb and get out there and plant those little darlings. lol I won't move any of the brugs out for another couple of weeks.
Kell, I think that at first I was keeping them too wet. Sadly, I didn't learn to keep them dry until it was too late. Next year, hopefully, I will know better, thanks to all the good advice I've gotten here.
