Tomato is the vegetable plant with the highest economic value. Production and commerce of tomato are continually increasing. Consequently, the study of control methods of tomato plant pathogens is of great importance for achieving a more efficient production. The relatively insufficient activity of chemical control and the absence of resistance in some tomato cultivars have focused interest on the practicality of biocontrol of F. oxysporum.The present work was undertaken to study the potential of Pseudomonas putida PCI2 as a biocontrol agent in the tomato-Fusarium oxysporum strain MR193 system and to detect production of bacterial compounds associated with increased plant resistance to fungal pathogens.
