Antifungal potential of biochar produced from wood was evaluated
against Fusarium oxysporum Schlecht. Methanol was used to prepare
biochar extract of which various concentrations were experienced in-vitro
against tested fungal strain. All the applied concentrations of methanol
extract i.e. 1%, 2%, 3%, 4%, 5%, 6%, 7% and 8% effectively inhibited F.
oxysporum growth. However, 7% and 8% concentrations were proved to
be most efficient in retarding the test fungus growth upto 15%.
Partitioning of biochar methanolic extract was done using some organic
solvents such as n-hexane, chloroform, ethyl acetate and n-butanol in
increasing the polarity order. These secluded fractions were further tested
to evaluate their in vitro antifungal activity along with a reference fungicide
(Mancozeb). Data obtained after 7 days of incubation depicts that
maximum antifungal activity was observed in fungicide with 89% inhibition
in the radial diameter of the test fungus. n-hexane and chloroform also
effectively retarded the growth of F. oxysporum, whereas n-butanol and
ethyl acetate fractions gave minimum activity . So it can be concluded
that wood biochar has the potential to control F. oxysporum
