Abstract—This paper discusses the in vitro synergy effect of syringic acid, caffeic acid and 4-hydroxybenzoic acid which found in oil palm root. Experiments were observed for fourteen days, repeated at least three times and data were recorded daily. The synergy effect of the phenolics against Ganoderma boninense were expressed in inhibition of radial growth of G. boninense on PDA ameliorated with the combination of either two or three different phenolics with concentration of 0.5 to 2.5 mg/ml. Several combinations showed strong fungit oxicity effect to G. boninense. Combinations of 4-hydroxybenzoic acid, syringic acid and caffeic acid up to 2.5 mg/ml strongly inhibited the growth of G. boninense in comparison to the control.
