Abstract
This
study aims to evaluate the antifungal activity of the aqueous extract of Trifolium resupinatum against nine phytopathogenic fungi (Fusarium solani, Fusarium
oxysporum, Fusarium proliferatum, Fusarium verticilliodes, Macrophomina
phaseolina, Curvularia austriaca, Drechslera halodes, Bipolaris sp.,
Alternaria alternata). The study was conducted using three
concentrations i.e., 5%, 10% and 20% of the T. resupinatum aqueous
extracts. Scanning Electron Microscopy (SEM) was employed to
examine ultrastructural alterations of treated and untreated mycelia of C.
austriaca. Fourier Transform Infrared (FTIR) spectrometry was used to detect significant
functional groups present in T. resupinatum aqueous extracts. T. resupinatum aqueous plant extracts showed effective activity against all selected
phytopathogenic fungi, based on concentration dependents. SEM of untreated
fungal cells did not exhibit structural changes, while treated cells exhibited
deformation of the cellular structure, distortion and folding of the outer
surfaces, and compacted conidia. FTIR spectrum demonstrated that T. resupinatum aqueous plant extracts exhibited various
reactive functional groups including alcohols, carboxylic acids and
aromatic substances. This study concluded that
the aqueous extract of T. resupinatum might be used as a
natural antifungal agent, which control infections caused by phytopathogenic
fungi in the agricultural fields.
