Hello,
Below are pictures of four Phrag besseaes with crown rot (I think). How can I cure it? I have access to a wide variety of fungicides (everything imaginable).
Also, can any one tell me what the name of the fungus is? I don't think its botrytis or fusarium.

Any help is appreciated.

Yuck!
I'm not going to be much help, sorry to say, no idea the type of fungus/bacteria - it looks dryer than botrytis to me. Never had anything like that on my plants, knock on wood!
Good luck!

I guess if I had to recommend something I'd cut out the infected parts (obviously) and dose w/ peroxide?

I have been seeing some rot in the greenhouse. Due to the cost of fuel this year the temps have been set lower and I think that is helping with crownrot. Also is is better to water early in the day, so the foliage is dry before night. Can't help with type of fungus or treatment. But I would toss single growth ones and remove the effected growth on multigrowth ones. Treat with a fungicide after removing growths and you might wish to consider treating your whole collection.

Unfortunately, most of the rot problems are difficult to cure. This looks like erwinia to me and is an occasional problem that needs attention immediately when seen. I use Phyton and hope for the best.

Good culture including excellent air movement and drying of the foliage prior to lights out are essential.

Kyle, that doesn't look too good and I agree with Jeff and Ron, provide lots of air movement. Good luck!

You don't want me to tell you what to do with it....... I would toss it, but that's me. I wouldn't want to spread that among all of my other plants, and by the time you get it back after nuking it, it will be years away from blooming. Just my unadulterated opinion. Take it with a grain of salt.

Frankly, I agree with KILLER (Tadd) there - but that's just me. I wouldn't wish it to spread! They look pretty far gone.

Like Tadd and Heather, I too would discard it and get another one. Too risky to spread it to my other healthy plants, just not worth all that time and energy spent on reviving it back to health.

Especially knowing where you are - probably they can spare the four....?
I'm not one to say that generally but these really look pretty far gone.

This happens with phrags sometimes from water sitting in the crown when temps are cool. I have seen it a few times. I use cinamon and sulphur and charcoal mixed at 1/3 parts each and rub on the infected parts and down in the crown. you may save it or it will send out a baby plant hopefully.
Good luck

Another thing that sometimes helps is: If you can, with a sterile tool, cut past the rot into the live, good tissue (if there is any) and then spray that with hydrogen peroxide -- available over the counter from places that sell first aid medications. Pull off any leaves that are totally rotted, including if that is the new center growth, and spray really well down into the crown and around the base of the plant. I agree that it may send out a keiki, if the roots are still healthy. But it will take a long time.

I agree with Tucker on this one.

Kyle this one is pretty far gone at this point. May take some extreme surgury to find anything green in the center. If that doesnt pan out then you better bury it. :(

Erwinia is a bacterial rot, and will not respond to many fungicides, unless they are all out disinfectants.

What might work then? A bacterialcide?

And, heather, the plants are division of some pretty important plants. It doesn't seem to be spreading to any new plants.

That's good it isn't spreading. Hope they make it! Good luck, let us know how things progress!
I'm always heartbroken when something like this, although rare so far, happens. Of course, we want every plant to survive, and thrive in our care!

Some people have had some success with Physan, hydrogen peroxide, and cinnomen (not neccessarily all at once). But success rates with Erwinia are poor.

I'm thinking of trying some powdered goldenseal root. Its a forest herb with antibiotic properties.

more than one growth in the pot ?? Are all growths effected or just one showing decline ? if it was a cherrished plant of mine -I'd tip out of the pot cut off infected growth seal the cut with some cinimmion and pot up in some new mix .
and just watch the watering .-I just hate seeing that rot
let us all know how you go -just remember it will take time to recover -- remember the plant on the compost heap someone posted about?
they are tough and some do survive 12mths down the track .--Billie
