First report of Ralstonia solanacearum causing bacterial wilt of eucalyptus in Ecuador.

In January 2018, eucalyptus trees showing wilt symptoms were identified in a commercial plantation located in the Quevedo Cantón, Los Ríos province, Ecuador. Disease incidence reached 40% of the eucalyptus field and affected plants displayed reddening and wilting of the foliage, leaf drop, branch dieback, and reduced growth, resembling bacterial wilting symptoms (Santiago et al., 2014).
