Abstract

In addition to Eutypa lata, which causes eutypa dieback, other species in the Diatrypaceae familyincluding Cryptovalsa, Cryptosphaeria, Diatrype, Diatrypella and Eutypella, are pathogens of grapevinesin Australia. In the study described here, upon inoculation, diatrypaceous fungi caused diseasesymptoms (lesions) at sites of infection and colonised grapevine wood, often in advance of visiblesymptoms. Remedial management for eutypa dieback advocates removal of diseased wood, as well as10cm of healthy tissue in advance of disease symptoms. The study showed this strategy is sufficient formanagement of these other diatrypaceous species. Furthermore, pruning wound protectants that havebeen shown to be effective against eutypa dieback are similarly efficacious against these other species.
