Abstract A bacterium, isolated from infected tubers of calla
(
Zantedeschia spp.), was confirmed as a soft rot pathogen by completion
of Koch's postulates and was identified as
Erwinia carotovora subsp.
carotovora (Jones 1901) Bergey et al. 1923. This paper confirms the
identity of
E. carotovora subsp
. carotovora as the cause of
bacterial soft rot of this important ornamental plant in New Zealand.
