Many studies have demonstrated the capacity of non-pathogenic strains of F. oxysporum to control Fusarium diseases.
These non-pathogenic strains show several modes of action contributing to their biocontrol capacity. They are able to
compete for nutrients in the soil, affecting the rate of chlamydospore germination and the saprophytic growth of the
pathogen, diminishing the probability for the pathogen to reach the root surface. They are competing with the pathogen
at the root surface for colonization of infection sites, and inside the root where they induce plant defence reactions. By
triggering the defence reactions, they induce systemic resistance of the plant. Depending on the strain, and on the plant
species, these mechanisms are more or less important, leading to a more or less efficient biocontrol efficacy.
