Título em português: Uso de pioverdina no controle da mancha bacteriana do maracujazeiro. aThe objective of this work was to evaluate the effect of a bacterial filtrate containing pyoverdine on the population dynamics of Xanthomonas axonopodis pv. passiflorae, and the severity of passion fruit bacterial blight. 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. aphylloplane aPseudomonas aSiderophores aPassiflora Edulis aSideróforo aFiloplano aSiderophore aXanthomonas axonopodis pv passiflorae1 aSOUZA, G.
