Validation and extension of management strategies for wheat powdery mildew locations
Aims

The objectives include validation of the effectiveness of varietal resistance, application rates and timing, efficacy of pre and post emergent fungicides to assess how different actives (DMI, QoI and SDHI fungicides) perform in the presence of resistant powdery mildew mutations.

In 2022 the project had three main field components

  • Investigating best management of wheat powdery mildew through small plot trials.
  • Surveying grower paddocks to determine frequency of mutations conferring reduced sensitivity or resistance to DMI and QoI fungicides.
  • Understanding the cause of spatial variability in mildew incidence related to soil type. Collecting samples from for nutrient analysis.
Key messages
  • Currently registered fungicide products from groups 3, 7 and 11 have not provided high levels of powdery mildew control in several field scenarios tested. The industry would benefit from access to alternative modes of action that have specific activity against wheat powdery mildew.Where multiple pathogens are present, multiple modes of action may be necessary that provide good control of all pathogens.
  • Low level varietal resistance, i.e. MSS is enough to significantly reduce WPM infection, compared with highly susceptible SVS varieties.
