The ability of two strains of Fusarium oxysporum, not pathogenic and saprophytic oil palm, to induce immune responses of oil palm against Fusarium wilt was evaluated. Healthy plants old 2 months were inoculated with some pathogenic strain and for others with saprophytic strain. Three days later, the treated plants were artificially infected with a strain of F. oxysporum f.sp. elaeidis responsible for Fusarium wilt of oil palm. The results of the experiments showed in control plants, not pre-inoculated, a rate (0.38) of diseased plants statistically higher (p <0.05) than those recorded in treated plants (0.14 and 0.28). Moreover, the lowest rate (0.14) of diseased plants obtained from plants treated with the saprophytic Fusarium strain shows that it is able to protect the palm against the superinfection by the strain of Fusarium wilt. © 2012 EuroJournals Publishing, Inc.
