Validating the SclerotiniaCM app for managing sclerotinia in canola

The aim of this work was to use a range of tools to determine if we can be confident that the SclerotiniaCM app is producing reliable outputs that will help canola growers make informed management decisions in a given season

Validation and demonstration of decision-making tools for managing blackleg in canola in the Western Region

The primary purpose of this project was to provide additional data from a range of different agricultural scenarios (climate, soil type, management practices) in the Western Region to validate and enhance the ability of the BlacklegCM app to more accurately determine the return on investment various management decisions may provide to a grower in any given year. The secondary purpose of this investment is to increase the grower and advisor confidence in the use of decision-making tools to manage disease in canola in the Western Region, in particular increase the awareness and use of the BlacklegCM app.

Validation and extension of management strategies for wheat powdery mildew

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.

Variable lime application trial

To address the following questions.

  • Is the variable lime technique applicable/economic in a pasture system or is it more suited to cropping systems?
  • Is it viable in the smaller size paddocks that are usual in pasture systems?
  • Can you measure economic gains using the technique in pasture paddocks?
