Fusarium-wilt suppressive soils from the Châteaurenard region : review of a 10-year study

This paper presents the main results obtained while studying the fusarium-wilt suppressiveness of Chateaurenard soil. Experimental data are discussed in relation to the main theories developed to explain the phenomena ot soil suppressiveness to fusarium wilts. This suppressiveness, based fundamentally on microbiological interactions, relies on the complementary association of a general mechanism of competition for nutrients between the whole soil microflora and the entire Fusarium population and intrageneric competition between pathogenic and non-pathogenic Fusarium. This research has led to new approaches for microbiological control of fusarium wilts.
