Abstract:
This study was conducted to isolate Fusarium oxysporum from salak madu (Salacca
sumatrana Becc.) and determine the suitable unripe papaya peel extract concentration
on inhibition of F. oxysporum under laboratory conditions. It is found that unripe papaya
extracts exhibited fungicidal effect against F.oxysporum at 0.08 gmr
1
in the in vitro
study. In the in vivo study, application of unripe papaya peel extracts at 0.24 gmr
1
had
antifungal activity against F.oxysporum curatively and protectively on salak fruits based
on quality attributes such as, disease severity, disease incidence, and flesh firmness as
compared to untreated fruits. However, protective and curative treatments had no
influence on pH, total soluble solid, chroma and hue angle on fruits. This result suggests
unripe papaya peel extracts has a potential to be used as a biofungicide against
Fusarium oxysporum of salak fruit.
