I'm Back!!!!!
But It's winter here in south africa and all my plants are in dormancy ( exept my seedlings) but one of my groups have a bad case of root rot!!!!
So i removed them from infected soil wased creaned off all dead and rotten plant material and used a lime -sulpher base fungicide.
I them layed the three seperate plants on wet cotton and lightly covered them.
they are under 20 hour photo period and 24 hour UV light
that should kill all bacteria

Sorry to hear about the root rot, but it sounds like you've come up with a good way of fighting it. I look forward to an update to hear how it's working! So glad to have you back on the site Anrich!

Sorry to hear about the root rot.. keeping the soil too wet is what did it in my case. I found a higher sand content prevented root rot due to the accidental over-watering here and there..

Guten Tag!!!
This rot is of a unique kind, the lime-sulpher treatment did not do the trick.
The next morning after the treatment there where clear signs fungi.
So what i did is removed all dead brown flesh trimmed all the foliage and soaked in a meth. spirits and water mix ( 10 ml meth. per 1000ml H2O) and applied more (but more potent) lime-sulpher mix
Then placed the rizomes on wet cotton in a tupper-ware lunch box and placed in the fridge as in Matt's fridge dormancy method
( it is winter at the moment so I guess this will do two things:
1: speed up the switch to dormancy
2: and kill all the spores and fungi as it is apparently very sensitive to cold temp.( below 5 Degree celcius)
I am quite sure that this may do the trick and if it does it may be a good method to use in the case of infection by a pathogen of extreme resiliance.
Ahoy please do tell me what you think !!!

Let us know how it works. It would be good to have some tried and prooven methods for battling these infections.

Yeah. Trial and error is the fundemental basis of science.
It is quite shocking how unstoppable an infection can be.
In such a case, the normal lime-sulpher treatments seems to be fulite and only shocks the plant more...
so, in the intrest of self-accumulated Knowledge, I shall sacrifice a few green dragons plants to the testing of this method, ( I supose i don't have a choice).
Sweet!!!

The fridge thing could work for the fungus infection, but to speed up the switch to dormancy I'm not so sure.
I was always under the impression you had to let your plants start dormancy naturally, and only put them in the fridge once dormancy was started already.

See winter has been freezing for a 30 days, and the plants where already somewhat into dormancy. so the fridge is the best option.
I checked again this morning and there where no sign of fungi, it's still a bit too soon to tell but, i think this method works!!
Ahoy
