Eutypa dieback (ED) is considered an important grapevine trunk disease (GTD) in Australia,
causing significant yield reduction and threatening the sustainability of vineyards. Eutypa
lata and other Diatrypaceae fungi produce ascospores that infect primarily through pruning
wounds resulting in cankers, dieback and eventually death of vines. Thus, understanding the
prevalence and distribution of these Diatrypaceae airborne spores in vineyards will help
elucidate their importance in disease spread and to develop subsequent disease
management strategies in vineyards. High resolution melting analysis (HRMA) is a simple
PCR-based method that has been applied widely for species identification and genotyping of
plant pathogens.

Conference24th Australasian Plant Pathology Society Conference 2023
Abbreviated titleChange and adaptation
OtherOn behalf of the organising and scientific committees we are pleased to announce the 2023 Australasian Plant Pathology Society Conference. The conference will be held in Adelaide, South Australia, 20 - 24 November at the National Wine Centre, corner of Botanic & Hackney Roads, Adelaide, South Australia. For those unable to attend face-to-face a virtual platform housing pre-recorded presentations, poster galley and virtual exhibition will be accessible to all delegates post event for 3 months.

The theme for the conference, “Change and Adaptation”, has been chosen to highlight the ever-changing nature of pathogens and the array of emerging technologies being developed to monitor and control disease.

Please join us to stay connected with colleagues, support our emerging scientists, and showcase and access the most recent plant pathology research, either online or in the relaxed and beautiful environment of Adelaide and its parklands.
