Yeah it is really a pain in the a**.. Sound like there are no actual cure after all.

Yeah seems difficult to cure once its infected a plant. The anubias in my tank is sending out new roots now and generally seems more healthy. This is a good sign since r. solani would inhibit root growth. I'll keep you up to date in my threads on how it's doing.
If things go bad I may try dosing my tank with KHCO3. people do dose it as a source of potassium:

Oh and once again my ideas on the effects of KHCO3 on the growth of R. solani came from Ismail Erper, Muharrem Turkkan, Gürsel H. Karaca and Gülay Kılıc, 'Evaluation of in vitro antifungal activity of potassium bicarbonate on Rhizoctonia solani AG 4 HG-I, Sclerotinia sclerotiorum and Trichoderma sp.', African Journal of Biotechnology (2011) Vol. 10(43), ISSN 1684–5315 © 2011 Academic Journals, 8605-8612

I'm convinced from my research [Erper, Turkkan, Karaca and Kılıcpp, 8605-8612] that there could be way of treating the condition with KHCO3 not just because of the potassium but because the fungus in question (probably R. Solani) and many other soil fungi cannot stand the buffering effect of the potassium bicarbonate. I read [Erper, Turkkan, Karaca and Kılıcpp, 8605-8612] that these fungi cannot grow when pH rises above ~ 8.4. This is high but anubias can go up to 8.6

Take a look at this excerpt from the Ismail Erper, Muharrem Turkkan, Gürsel H. Karaca and Gülay Kılıc, 'Evaluation of in vitro antifungal activity of potassium bicarbonate on Rhizoctonia solani AG 4 HG-I, Sclerotinia sclerotiorum and Trichoderma sp.', African Journal of Biotechnology (2011) Vol. 10(43), ISSN 1684–5315 © 2011 Academic Journals, at pp. 8611


"Soil fungi are more active under acidic pH values
(Ordonez et al., 2009). Previous studies showed that pH
changes of medium due to use of bicarbonates prevented
or stimulated the mycelial growth of fungi (Punja and
Grogan 1982; Palmer et al., 1997). S. rolfsii showed
optimal mycelial growth and sclerotial germination at low
pH (3.0-5.5), while no growth occur above pH (8.0).
Preventive effect of potassium bicarbonate on mycelial
growth of soil pathogens may be partially explained by
pH changes, which became more alkaline as bicarbonate
concentration increased. Our result showed that S.
sclerotiorum could not grow at pH 8.3 (at 100mM
KHCO3), and R. solani could not grow at pH 8.4 (at
750mM KHCO3). Increasing concentrations of KHCO3
caused growth reduction of both fungal strains. Similar
inhibition effects were observed for B. cinerea when
exposed to 20 mM of KHCO3 (Palmer et al., 1997).
Bicarbonates may also affect membrane permeability and
change physiological processes such as oxidative
phosphorylation [Olivier et al., 1998]. "

If the conditions at least severely inhibit the growth of the fungi and the plant has much potassium available to help strengthen it's cell wall and epidermis I think it might actually recover.

I'll try differentconcentrations of KHCO3 on some anubias and four or more other aquatic plants and see what works for these.


Oh and in many of our aquariums we like soft acidic water, the fungi in this research showed optimal growth at pH values around 6. When the water is soft the various fungi, not just R. Solani grew faster in the experiment carried out [Erper, Turkkan, Karaca and Kılıcpp, p. 8605-8612]. Many Anubias come from West Africa and from what I saw from the youtube video linked a few posts back, I also do not think this soft water does them well.

I'm gonna continue experimenting with concentrations of KHCO3 like I did with club soda on aquatic plants grown out of water. This time I'll use different concentrations of KHCO3 I've acquired. I'll work out concentrations of KHCO3 on my tank to figure out how to treat fungal infections of aquatic plants submersed. I've managed to find some KHCO3 and am continuing experiments now.

I have three little anubias nana petite, which I kept for a very long time, only two are unaffected, one died. The two survived from the disease. Lately, I bought some more expensive anubias again, yes I am desperate, and they are all died too, some half-live, some have root problem... now I am wondering why the very early nana petite are ok, and the rest is not?

What would happen if you left the infected Anubias plants floating in a tank with ramshorn snails? Perhaps the snails would eat the infected portions. It might be worth a try.

Tissue culture with sick plants?
I don't think that is a good idea, the disease will pass on.

Shark,

how are the plants doing now?

Did they recover a bit? any growth?

I think those plant we bought home which melted away was submerged grown, they tend not to accommodate too well in the new environment.

I got this conclusion from my own experience, I put all my anubias in a emsered tank, when some got dry leaf, some did not dry up, those did not dry up never caught the disease.


Regards
