The objective of the study was to investigate antifungal activity of Eusiderin I from Eusideroxylon zwagery by determining the inhibition zone of Eusiderin I against some pathogenic plant fungus. The antifungal activity were determined in a series of Eusiderin I concentration using agar well diffusion method. The antifungal activities of Eusiderin I (at 3, 4 and 5 ppm concentration) from E. Zwagery were tested against four plant pathogenic fungals such as Fusarium oxysporum f.sp. lycopersici, Sclerotium roefsii, Rhizoctonia solani and Gliocladium fimbriatum. Inhibition zone were compared with that of chloroform‘s as solvent. The results showed that the remarkable inhibition on the fungal growth was shown against the tested organisms. Eusiderin I, as major component of E. zwagery showed potent antifungal activity against Fusarium oxysporum f.sp. lycopersici, Sclerotium roefsii and Rhizoctonia solani. At 5 ppm concentration, it gave the most effective inhibition (49.80%) against the colony growth of Fusarium oxysporum f.sp. lycopersici. Whilst inhibitory activity against the growth of Gliocladium fimbriatum colony was not found. The result was in line with Gliocladium fimbriatum’s nature as antagonist agent against various pathogenic plants and it is very well known as a biological control.
