Given what has been stated above, the aim of the present work is to assess, in tomato plants, the antagonist effect of nonpathogenic Fo47 on the pathogen Forl, where two bioassays were used in which, the investigated mechanisms involved the direct antagonism, including a competition for nutrients and root colonization, using a temporal separation of the antagonist and the pathogen on the one hand and inducing systemic resistance to the tomato plant, using a physically separation of the antagonist and the pathogen to the same plant root level with a split root method on the other.
