Abstract:
Pseudomonas viridiflava is reported causing a disease of hellebore (Helleborus × hybridus) in New Zealand. The bacterium was isolated from diseased plants exhibiting distinct symptoms consisting of black leaf spots, necrotic petal and stem lesions. P. viridiflava was identified on the basis of biochemical and molecular tests and confirmed as the causal agent by fulfilling Koch’s postulates.
