During the Christmas and New Year period, extensive rainfall, and hail in some regions, affected several grapegrowing regions in Australia. These conditions were conducive to the development of diseases such as downy mildew, powdery mildew and Botrytis in grapevines. Tools and resources available to grapegrowers and winemakers to manage disease assessments are detailed within this Ask the AWRI article on assessing grapes for disease.

Looking ahead, the forecast for rainfall from January to March suggests a likelihood of above-median rainfall in the south-east, while the north and west of Australia may experience below-median rainfall. Immediate action is crucial to mitigate the risk of significant crop losses from disease. This eBulletin outlines strategies to reduce both the risk and severity of fungal infections during periods of heightened disease pressure.

The bulletin includes important information surrounding:
  • General tips for best-practice disease control
  • Downy mildew
  • Powdery mildew
  • Botrytis bunch rot
  • Additional resources on fungal diseases and dealing with wet conditions
