The virulences of three isolates of Fusarium oxysporum f.sp. elaeidis from West Africa were compared with that of a Brazilian isolate. The Brazilian strain was more virulent and caused disease in all oil‐palm lines tested, even those which had been selected for resistance to, and were generally unaffected by, African strains. Differential interactions between hosts and isolates of the pathogen could have serious implications for selection of breeding material and for the extension of oil‐palm cultivation in South America.
