fungicide resistance
Understanding fungicide resistance in Australian vineyards By The Fungicide Resistance Project Team#* *Corresponding author: Barbara Hall, SARDI. Email: Barbara.Hall@sa.gov.au
A project involving research partner organisations from across Australia is studying three key pathogens affecting the nation’s vineyards.
A
collaborative project funded by GWRDC is under way involving industry partners and researchers from SARDI, Curtin University, National Wine and Grape Industry Centre, Department of Agriculture & Food WA, AWRI, and The University of Adelaide. Three key pathogens affecting Australian vineyards will be targeted: Botrytis cinerea, Erysiphe necator and Plasmopara viticola.
Although there are currently a number of fungicide groups available for these pathogens, the investment required to discover and develop new molecules is in the order of $300-400 million. It is, therefore, important to manage the existing chemistries to ensure that they continue to provide effective control. This project will provide comprehensive information on the fungicide sensitivity of these pathogens, the incidence and distribution of resistant populations, and
improve knowledge about the mechanisms of fungicide resistance in Australia to the main fungicides used. The information will contribute to improved fungicide resistance management strategies through collaboration with CropLife, agrochemical companies and industry. Maintaining the effective use of all fungicides will contribute significantly to the objective of reducing the economic and environmental impact of disease in Australian vineyards for the future.
