Podcasts
A total of 12 podcasts are available in three series of podcasts.
All podcasts are available on the AFREN website or on most podcast streaming services.
Fact sheets
Two general fact sheets – on Fungicides in Australia and How Fungicide Resistance Develops – have also been produced.
Webinars
Videos
Three videos have been produced to help growers understand how fungicide resistance develops and how you can prevent it from becoming an issue in your cropping programs. The videos are available online.
Case studies
AFREN case study – blackleg Wimmera
The Wimmera has many cereal and pulse options, which facilitates the use of good agronomic practices such as allowing three or four years between canola rotations and separating new crops from previous seasons’ stubble. These practices should help keep disease pressure at moderate levels. However, blackleg can still be an issue in above-average rainfall years and for individual crops.
AFREN case study – blackleg lower EP
While Lower Eyre Peninsula canola growers have gained new fungicides for the control of blackleg, simply replacing DMIs with repeated or high frequency use of SDHIs could encourage new resistant strains of the pathogen.
Local growers and agronomists will be able to protect the long-term effectiveness of their new fungicides by strategically using these fungicides when they are most likely to result in an economic yield gain.
AFREN case study – net form net blotch
Barley growers on South Australia’s Yorke Peninsula have seen how quickly fungicide resistance can turn from a potential problem to serious threat in the absence of good management practices.
Sam Holmes is an experienced agronomist in the region, where barley has proven to be a reliable and economically successful crop over many years.
AFREN case study – septoria tritici blotch
Tasmanian wheat growers enjoy a cool climate, relatively high rainfall and long growing season.
However, those cool, moist growing conditions lead to considerable disease pressure from Septoria tritici blotch (STB).

FUNGICIDE RESISTANCE WORKSHOP SERIES:
Managing cereal and canola foliar diseases and fungicide resistance
Agronomists and grain growers are invited to discuss the cutting edge of disease and fungicide resistance management in a 2-day GRDC-supported workshop, brought to you by the Australian Fungicide Resistance Extension Network (AFREN).
Workshop facilitator John Cameron said “The 2024 foliar disease and resistance workshops continue on from previous, highly regarded, workshops providing the latest research on foliar disease and resistance in canola and cereals.”
“When you put Nick Poole from FAR Australia alongside resistance expert Fran Lopez from CCDM and key regional pathologists and mix this with the field expertise of 20 leading agronomists, the discussion will be lively and targeted on issues of regional importance and how this is reflected in advice to growers. It’s a great mix, and all who attend – no matter how experienced, will pick up new and valued understanding.”
These ‘small group’ workshops cover:
- Cereal growth stages and spray decisions
- Where different fungicides fit
- Fungicide resistance management and resources
- Integrating fungicides, varieties, epidemiology, and seasons for fun and profit
- Cereal canopy management interactions with foliar disease decision making
- Management strategies that consider the underlying risk of fungicide resistance
- Strategies for managing SDHI and other resistance issues, including net blotches in barley and triazole resistance in powdery mildew
- Canola/pulse disease management & fungicide resistance considerations (location specific)
These small group workshops will run for 2-days. Participant numbers are limited to ensure active participation and discussion. Workshops start at 9:00am day 1, 8:00am day 2 and finish day 2 by 4:00pm.
Cost is $165 ($150 + GST) per workshop.
Registration is essential to secure your place. Enquiries or to register interest in attending a workshop near you, please contact ICAN: Ph: 02 9482 4930 or erica@icanrural.com.au, or fill in the online registration form.
