Summary The susceptibility of Ophiostoma piceaperdum (n = 17) and O. bicolor isolates (n = 7) to catechin and resveratrol has been investigated with growth bioassays on malt‐agar medium. While catechin (10 −3 m ) did not have any significant influence, resveratrol (10 −3 m ) inhibited the growth of the two species, particularly the growth of O. piceaperdum isolates. We did not observe any synergistic inhibitory effect between the two phenolic compounds. Significant differences either in fungal growth on malt agar medium or susceptibility to resveratrol occurred among isolates for both species. Our results corroborate previous observations of high genetic and virulence variability among isolates of ophiostomatoid fungi and indicate that further studies should take into account the intraspecific variability of the fungal species of this group.
