by Robyn Mills, University of Adelaide Grapevine trunk disease is estimated to cost the Australian wine sector millions of dollars in lost production each year, but now grapegrowers have a new tool to better manage its impact. The University of Adelaide and Wine Australia have joined forces with the South Australian Research and Development Institute (SARDI) to update the Grape Assess app – released in June this year – with the latest research on grapevine trunk disease, adding to the existing range of grapevine disease and disorder evaluations within the app. Eileen Scott, Professor of Plant Pathology at the University of Adelaide's School of Agriculture, Food and Wine, said the updated app will simplify the assessment and management of grapevine trunk disease.
