Potential for fungicide resistance detected in Esperance wheat powdery mildew
Laboratory analysis of wheat powdery mildew samples collected from the Esperance district in Western Australia has revealed the presence of a gateway mutation that could lead to reduced sensitivity or resistance to azole/demethylase inhibitor (DMI) fungicides.
SDHI fungicide resistance detected in the blackleg fungus
Canola growers should take steps to reduce fungicide resistance developing following a detection of SDHI fungicide resistance in the blackleg fungus from samples taken from the Eyre Peninsula, South Australia.
New app paints clear picture of pesticide and fungicide resistance across Australia
A new data visualisation tool can display the distribution and severity of pesticide resistance across Australia, enabling growers and agronomists to make better, data-driven crop management decisions relevant to their region.
Tomorrow’s fungicides: gene switches and nanobots
New tools and techniques are being added to the fungicide resistance management arsenal.
‘Next-gen’ monitoring improving fungicide resistance detection
Like human diseases such as cancer, early detection and monitoring is crucial to keeping crops a step ahead of fungicide resistance.

If you’re interested in having one of our team present an information session on fungicide resistance to your grower or advisory group, please get in touch.
We have regional pathologists in all states, and can deliver in person or online.
Share your experiences with fungal pathogens and fungicide resistance with AFREN and other farmers. Upload photos of fungal infections in your crops, or your stories of fungicide resistance.
Please provide as much information as possible in the upload form.
