"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]. "
Based on this data the conditions with KHCO3 will at least severely inhibit the growth of the fungi.
Questo è preso da una rivista africana della biotecnologia proprio sui funghi delle piante.
Non è un dato provato sulle
Anubias ma si può sempre provare.
In poche parole si allontana la pianta colpita e si inserisce in una vasca con ph basico intorno al valore di 8/8,5 e con l' aggiunta di bicarbonato di potassio direttamente sul rizoma e sciolto in acqua il fungo dovrebbe morire lasciando il tempo alla pianta di riprendersi.
Potresti provare e farci sapere come procede.
