In the present study, TiO2 nanoparticles were synthesized by ultrasonic cleaning bath method using titanium tetraisopropoxide (TTIP) as a precursor. TiO2 nanoparticle was used as an antifungal candidate against Fusarium oxysporum, which causes wilting disease in plants. TiO2 nanoparticles were characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). The X-ray diffraction pattern showed the diffraction peaks associated with the anatase TiO2 crystal field. In addition, it was found that TiO2 nanoparticles were distributed uniformly and globular. TiO2 nanoparticles indicated a better antifungal activity against Fusarium oxysporum under UV irradiation than without UV irradiation. The minimum mortality rate using TiO2 nanoparticles without irradiation is 36.25% at a concentration of 8%. Meanwhile, with UV irradiation, the minimum mortality of rate was 88.46% with the same concentration. Our findings indicated that TiO2 nanoparticles with UV irradiation have antifungal activity against Fusarium oxysporum.
