Stangelbrand, i belive fusarium fungi...on two plants. pics so you will know what to look for. i do not believe i sent it to anyone as i believe the fungus is soil born and i haven't sent out nasty looking cuttings. from my reading so far, to prevent: good sanitation, control of fungas gnats, prophylactic fungicide.
Did you read this also? Its about soil ph levels and temperatures plus nutrient deficiency and how that make plants susceptible. I hope Susie is around. She know exactly what spray to use :)

Sorry Tonny, I couldn't get any fungicide to work. I got a plant last year(don't ask from whom, I can't remember) that had it and it does spread. Our ag dept just called it "stem rot" and recommended several fungicides. None worked. I tossed the plants. Some stem rots are also caused by bacteria, no fungicide will work on a bacterium.
Susie, i'm tossing the plants. it's strange, they are far apart and both in pots. got rid of one this afternoon, will the other tomorrow. i did get a fungicide to use around the areas where the plants were, that may work on brown spot too. guess i'll find out.
I think this is what I had on my brug last year that I lost. In fact, I lost three or four of them. It didn't seem to move to any of the others, but it was a stem rot right at the soil line. I was a nervous wreck. Everything looks good this year so far. I certainly will be very careful when I take cuttings to send. Might be smart not to send any this year. If I don't see any symptoms, should I be okay?
No, I had root rot, not stem rot. Sorry!!

Brugie, i am so confused. the leaves on these 2 plants don't show signs at all. also, the stem rot is probably kind of like the same thing, when i've been looking this up some call it crown/root rot caused by this. are you talking about the plants you lost last summer after you planted them in the ground?
Brugie, I think if yours are okay this year, they should be fine. I haven't had any new outbreaks either. Did yours seem to be only on the yellow flowered hybrids?
Dark Rosetta had something like this, but not sure if its the same fungus or bacteria causing the trouble in your plant, Arlene.

Tonny, that is the problem i confused with stangelbrand, and thought that i had, but no realize it is the fungus. but the leaves do not look bad, they aren't a dark green, but they aren't yellow.
If it is fungus is it then not possible to treat the plant or to take cuttings from a fungal free place on it?
Tonny, they aren't important brugs for me, i figure i won't take any chances, don't want it to spread. I read there are 24 types of that fungus in hawaii, and i think Susie is right, it's possible it could be caused from a bacteria also. It seems everything i read said to destroy infected plants. my impression is that a fungicide might help prevent a plant from getting it but won't cure it.
I got this too, on some cuttings, only affected the yellows. I too got rid of them..... It did not appear to affect anything except, that it makes the plant very weak at that point, but who wants to take any chances. Arlene if you find anything that works on it, let us know!
Destroying has got to be the best thing, get rid of disease prone plants! this will be the first day i ever bleached a shovel....
Edited to say, I wanted to let everyone know about this, what it looks like, and that it can happen. i feel kind of like when my kid got lice and i called all his friends mom's, lol.

Arlene, I had to do that too!! Just wish the mom of the kid who shared her head lice with everyone(at a sleep-over) had been nice and told us! I sure hated to make those phone calls!
lol.. there were about 4-5 kids over riding go carts, sharing helmets. all of the moms said their kids never got them, lol....
this link is really really gross, only for the strong. there are pics of fusarium fungi on a woman. I am now quitting looking up info on fungi. i am going to take a shower and hire someone to come destroy all my plants. well not quite yet.
btw, Ms Brugie, this fungus has a sister that affects crowns of plants.

Susie, should i bleach my tools? will that get rid of fungi?
OH MY GOSH,Arlene,Bleach your body!!!!! Quick!!!!
that stuff is awfull!!!!Can you imagine explaining how you got a soil borne fungus on your face?That poor woman!
Although that was the least of her problems.....
Arlene, some of the links I found said bleach won't kill the fungus, but ammonia will. So I'd use ammonia(like we used to scrub floors with) to clean the tools.
One of Bill's childhood friends caught a fungus while landscaping where a chicken farm had been years ago. He is a professional landscaper. He almost died from fungal mennengitis(spelling?) The doctors said it was a soil borne fungus that he had caught.
This stuff is scary. I'm glad I didn't reuse those pots the plants were growing in!
There are lots of different kinds of fusarium, one kind causes a wilt in tomatoes. Some varieties are resistant and it's listed on the tag. The tags will have letters above or below the variety name like T,F,V etc. The F is for fusarium resistance. Fusarium stem rot is a bad pest in tomato and pepper crops for farmers because of it's fast spread and no fungicide works once the plant is infected. I did read that copper based fungicides can offer some protection to healthy(noninfected) plants when used as a preventative.
CC, isn't that terrible? Susie, thanks for the info. i wonder what it would cost to have some one come in and big tent 6 acres....
I bet it would cost a lot, plus you and your family(plus pets) would have to stay somewhere else. If you use Methylbromide it will kill everything, butterflies, worms, good stuff.....everything.
I think just getting rid of the infected plants and disinfecting all equipment should be sufficient. You might take a plant to the dept of ag to let them test it to be sure what it is. Pythium stem rot is similiar(but it makes fuzzy stuff at the site of infection) and bacterial stem rot looks a lot like fusarium. Most extension services(run thru your state's university in conjunction with the USDA) offer testing services free or at low cost to gardeners.
so ammonia kills all bad things Susie??? Can I stop boiling all my clippers for 5 minutes? LOL. and I just bought a special pot a few weeks ago to use for my DH would get so mad when I used his circulon. LOL
Susie,
I have used subdue to cure rot in daylilies and it does work.I've had many people tell me that you can't cure it but this stuff did it. Do you think it would work for this? The only drawback I found with using it is the fact that it costs about five hundred dollars per gallon.I was fortunate enough to have had some shared with me through my job. And a little goes a loooong way.
Catsmeow, I tried it last year, no luck. I know what you mean about the price!
Last year I tried Chipco, Cleary's 3336, Banrot and Subdue Maxx(not all at once, but sometimes on separate plants and some were a couple of weeks between chemicals). None of them stopped it from spreading or cured it once it got in the plant.
Kell, I don't know if ammonia kills all germs, but several websites for tomato/pepper growers recommended ammonia to kill fusarium on equipment and they all said bleach does not kill it. There is something called Zerotol(another expensive one) that is a disinfectant that should kill it. It is Hydrogen Dioxide, it's very corrosive.
It is late for me to be up. Have company all weeekend, so will get back her later on Sunday. Whatever I had affected Species, Pink Beauty, Creamsickle, and one other one that I can't remember the name of right now. I'll check back in when my brain is functioning better. I haven't even read the above yet, but I'll catch up. Thanks...........
Cala, I notice bleach really rusts out my clippers. I may try ammonia. I used to carry bleach around with me in a spray bottle to use after each pruning I made on a plant. Now I will put in ammonia.
Kell, DO NOT mix the bleach and ammonia. It will kill you to breathe the fumes.
I learned that on a sanitary course many years ago. Now, I liked to test other peoples statements already then to see, if I would come up with the same results (a bad hobby that is sometimes also quite amusing). Glad that I was able to control my curiousity :D
Thanks Cala, I won't! You are stuck with me for awhile more!
I thought this was interesting. I havent heard of the ammonia on the tools, do yall still do this? I sure want to keep my babies healthy. (without rusting the tools)
Shelly,
.......Ammonia and alcohol are cleaning agents not a disinfectant. When it comes to germs and viruses common household bleach at a 10(water) to 1(Bleach) ratio works great.
........After that you need to move up to chemicals such as Physan

.............More recently, we showed that Fusarium oxysporum and many other soil fungi are also capable of anaerobic metabolism of nitrate to form ammonium
(4).''' This so-called ammonia fermentation can support anoxic growth of fungi even under complete loss of oxygen supply.''' Under such anoxic conditions, the fungal cells were shown to contain many apparently immature mitochondria
(4). By contrast, fungal denitrification requires a minimal amount of oxygen supply (5), and the denitrifying cells grown under the micro-aerobic (hypoxic) conditions contain apparently intact mitochondria (6), consistent with our previous observation that the fungal denitrification system is localized in mitochondria (7). Therefore, these soil fungi can adapt immediately to rapid changes in environmental oxygen supply by changing their energy metabolism: ammonia fermentation under anoxic conditions, denitrification under hypoxic conditions, and oxygen respiration under aerobic conditions........

What did I just read? LOL!! Don't understand a word of it...well, few words anyway. I'll leave it up to others to figure it out. While you all are doing that, I'm going to go water my brugs.
LOL Brugie. I am with you! So was that for or against, Scoot? LOL
Ummm.......
Errrrr..........
I kinda hoped one of you 'experts' would know ;-P
Part of it sounds kina like 'da fungi likes the nitrogen aka ammonia...? ? ? ?
Gotta start sumpin new to discuss...'s gettin' too dang quiet around here =)
kell, I tell ya what "I'm" for.........
I Wanna Be Susie's Next-Door Neighbor.( Whine! )
;~P
Sounds like ammonia(NH3)which contains nitrogen will promote instead of inhibit the growth of the fungus according to that. I vote for Physan, or maybe really strong Hydrogen Peroxide(35% which is VERY caustic). I bet boiling the tools like Kell does would work too.
The liquid nitrogen that we apply to our corn fields is ammonia =)
.......
..............The majority of all ammonia and ammonium nitrate producted is for use as fertilizer. Approximately 70% of all NH3 produced is directly used for fertilizer. Farmers inject the pressurized liquid ammonia into the soil. Ammonia is so soluble in water and has such a high affinity for polar groups such as hydroxyl groups that the ammonia is almost instantly taken up by the soil and very little is lost to the atmosphere.

Wow!! Thanks for all the info ladies!! I bought some physan on ebay. Should be coming.
Im glad you cleared that all up Susie.. lol I didnt know what that stuff said either. :o)
Im getting paranoid about my plants now.. lol is that a bad thing?
Nah! Totally normal for us ...hahaha !
