This study aimed to identify potential alternative hosts of Xanthomonas campestris pv. viticola (Xcv), to provide data for the management of bacterial canker of grapevine. Twenty-six plant species were artificially inoculated with the strain Xcv3 and maintained under greenhouse conditions where the development of disease symptoms, such as angular necrotic spots and rib lesions were evaluated. The Xcv3 was reisolated from each symptomatic alternative host, and identified using PCR (Polymerase Chain Reaction) with specific primers. The inoculated species that showed typical disease symptoms were Glycine sp., Senna obtusifolia, Desmodium discolor, Amaranthus deflexus, Azadirachta indica, Solanum lycopersicum and Vigna unguiculata. Species of the family Poaceae, Bidens pilosa, Emilia fosbergii, Praxelis pauciflora, Macroptilium lathyroides and Portulaca oleracea were not showed during the period of evaluation.
