Abstract A stem canker disease of a
Limonium hybrid
`Chorus Magenta' was identified at several sites throughout the North Island of
New Zealand. First symptoms included leaves of diseased plants turning yellow,
often on one side of the leaf blades. Cankers developed blue-black
discoloration, and dark fruiting bodies of a fungus were located below the
epidermis of cankers on dying plants. A
Phomopsis sp. was consistently
isolated from diseased stem tissue. Pathogenicity was confirmed by inoculating
healthy plants with the fungus in the greenhouse. The pathogen was recognised
as a new species and named
Phomopsis limonii. This is the first report
of
Phomopsis on
Limonium.
Keywords Limonium sp.; canker; plant disease;
