Fungicide resistance in powdery and downy mildew is a growing challenge in Australian vineyards. Ismail Ahmed Ismail, Senior Research Officer at the South Australian Research and Development Institute, discusses a decade-long national study on fungicide resistance in Australian vineyards. Listeners will learn how spore trapping is being made practical and affordable, the use of phenotyping and genotyping to detect resistance, and why monitoring fungal populations is critical for sustainable disease management across FRAC groups.
