The results of pH studies also demonstrated all eight fungi tested to be capable of growth in
both acidic and basic environments, although the growth of some species was inhibited at
the lowest value tested (pH 2), and the growth of all species was totally inhibited at the
highest value tested (pH 12).

The efficacy of 20 organic and inorganic sodium salts, and two synthetic fungicides against
eight bean root rot pathogens-Fusarium equiseti, F. proliferatum, F. semitectum, F. solani f.
sp. phaseoli, F. verticillioides, Rhizoctonia solani AG4-HG I, Macrophomina phaseolina and
Sclerotium rolfsii-were evaluated in this study. Accordingly to preliminary in vitro tests, only
captan, benzoate and metabisulfite (2%) were able to completely inhibit mycelial growth of
all eight fungi. Moreover, no significant differences were observed among the inhibitory …
