The treatments were: King’s B medium solution; King’s B medium solution with 2 μmol L-1 Fe2+ supplementation; and King’s B medium filtrate containing two concentrations of the siderophore pyoverdine produced by Pseudomonas sp. The filtrate containing pyoverdine at Abs363 = 0.231 (highest concentration) reduces the number of cells of X. axonopodis pv. passiflorae, and at Abs363= 0.115 and Abs = 0.231 significantly reduces the severity of bacterial blight.
