Abstract

A new disease of jojoba in Australia is described. We have demonstrated that this disease is caused by Elsinoë australis, a pathogen which is normally associated with citrus. This pathogen has not been found previously in Australia on citrus or any other crop. The fungus causes a scab on leaves and stems of jojoba and is widely distributed in eastern Australia. Although molecular analysis of the pathogen indicates that it is closely related to the natsudaidai and the sweet orange pathotypes of E. australis, glasshouse and laboratory experiments demonstrate that it is not pathogenic to a range of citrus cultivars grown in Australia. The data indicate that the isolates from jojoba represent a new pathotype of E. australis.
