Conteúdo: | In March 2017, canker symptoms were observed in the branches and stems of several apple trees (Malus pumila) in an orchard located at the EPAGRI Experiment Station of Caçador in Santa Catarina State, Brazil. Intense bacterial exudation from wounds caused by pruning, and colonisation and discoloration of the pith and conducting vessels, especially the xylem, was observed (Fig. 2). The leaves of affected trees wilted and ultimately trees died. A bacterium was isolated from affected plants and identified by biochemical and moleculares tests. To our knowledge, this is the first report of D. dadantii causing disease in an apple tree in the world. Our proposal is that the disease should be called "Dickeya canker"
