Abstract
Botrytis cinerea was isolated from Geraldton waxflower (Chamelaucium uncinatum) flowers collected in Queensland and Western Australia. Isolates were shown to be pathogenic on the two flower selections used, ‘Herb Morrow’ and ‘Alba’. Separation of the flower from the pedicel occurred for single cut flowers inoculated with the fungus. This observation supports the hypothesis that infection commonly contributes to premature flower drop in cut, packaged Geraldton waxflower.
