Inhibitory Effects On Leaf Extracts Of Three Indigenous Medicinal Plants On Fungi Responsible For Post-Harvest Rot Of Banana In Abia State:-Best, Sophia Chinyere
ABSTRACT
This study was conducted in order
to isolate and identify fungi causing rot of banana fruit in Umudike Umuahia to
determine the inhibitory effects of 3 indigenous plant extracts in two solvents
which were methanol and acetone, the phytochemical components of the leaves of
the three indigenous plants was also investigated. The experiment was done in 3
replicates and ANOVA was used to analyze the data gotten after 5 days of
inoculation. The results showed the inhibition level of plant extracts on the
fungi isolated (Fusarium, Rhizopus, Rhizoctonia) were 72.6 ± 9.9 for plants
extracted with methanol at 100% concentration and 78.43 ± 11.3 for plants
extracted with acetone at 50% concentration. The acetone extracts ofX.
aethiopica was more effective than that of Garcinia kola and Vernonia
amygdalina in the control of Fusarium spp~, the acetone extract of G. kola was
more effective than that of X. aethiopica and Vernonia amygdalina in the
control ofRhizopus spp and the methanolic extracts of G.kola and X. aethiopica
was more effective in the control Rhizoctonia sp\> than that of V.
amygdalina. Phytochemical analysis of the leaves of the three plants extracted
with Acetone and Methanol showed that the plants contained Saponin, tannins,
alkaloids, phenol, flavonoid and hydrogen cyanide, Though tannins were not
detected in the the plants extracted with acetone. However hydrogen cyanide showed
a high amount above 1.4 in the plants extracted with acetone. The isolation
from rotten banana had the Rhizoctonia spp of a high occurrence in isolated
organisms and Rhizopus as the least present in the isolated fungal pathogen of
banana rot
