Coutinho, T.A., Priesig, O., Mergaert, J., Cnockaert, M.C., Riedel, K.H, Swings, J., and Wingfield, M.J. 2002. Bacterial blight and dieback of Eucalyptus species, hybrids, and clones in South Africa. Plant Disease 86: 20-25.
In 1998, a new disease spread among Eucalyptus nurseries and plantations throughout South Africa. The causal agent has now been identified as Pantoea ananatis, a bacterium formerly known as a species of Erwinia, and is the first report of a member of the genus Pantoea infecting Eucalyptus. Typically, the pathogen causes leaf blight and dieback of young shoots on its host. In nurseries where new plants are propagated vegetatively, the bacterium affects both cuttings and ramets, reducing their ability to root by nearly 100%. In the past, Pantoea ananatis has also been reported as a pathogenic agent on cantaloupe fruit, sugarcane, onions, and honeydew melon.
