  • Fusarium oxysporum f. sp. radicis lycopersici and Fusarium oxysporum f. sp. lycopersici represent a high threat for tomato crops. Banning of methyl bromide fumigation associated with the increasing demand for safer crop production led to consider new management strategies for the control of these two phytopathogenic fungi. One of these strategies relies on the selection and exploitation of antagonistic bacteria able to protect the plants against these fungal pathogens. The genus Pseudomonas represents a reservoir of potential antagonistic agents against several phytopathogenic Fusarium species. In this work, five fluorescent pseudomonad strains were characterized for their antagonistic attitudes by scoring siderophore, protease and antibiotic production and by evaluating the inhibition of mycelial growth of both Fusarium species in vitro. Moreover the production of quorum sensing signals by Pseudomonas strains was assessed by using the two biosensor strains Chromobacterium violaceum CV026 and Agrobacterium tumefaciens NTL4. Finally the five strains were evaluated for the control of both phytopathogenic fungi on tomato plantlets with an useful and predictive in vivo approach. Results showed that P. chlororaphis strain M71 was the only pseudomonad able to produce siderophores, proteases, antibiotics and quorum sensing signals. Furthermore, this bacterial strain resulted to be significantly effective in the reduction of disease gravity in both cases while the other pseudomonad strains, belonging to P. fluorescens group failed to protect tomato plantlets.
