DMI resistance in wheat powdery mildew confirmed for the first time
New South Wales and Victorian grain growers are urged to be on alert following confirmation that difficulties experienced in 2020 controlling wheat powdery mildew are linked to resistance of the pathogen to demethylase inhibitor (DMI, Group 3) fungicides.
AFREN support network to tackle fungicide resistance
With the right support, growers and advisers can successfully manage and prevent fungicide resistance.
With the increasing use of fungicides for disease control in crops over the past 20 years, there has been a corresponding rise in cases of fungicide resistance in many common pathogens.
Latest fungicide resistance research has once again reinforced the value of integrated disease management strategies
Latest fungicide resistance research, led by the Centre for Crop and Disease Management (CCDM) in collaboration with plant pathologists from Department of Primary Industries and Regional Development – DPIRD has once again reinforced the value in growers adopting integrated disease management strategies for their crops.
GRDC podcast highlights AFREN resources and fungicide management recommendations
A new GRDC podcast gives you the perfect introduction to the Australian Fungicide Resistance Extension Network (AFREN), including the range of resources you can access and how to limit your fungicide resistance risk.
AFREN launches small group workshops on managing cereal and canola foliar diseases and fungicide resistance
Agronomists and grain growers are invited to discuss the cutting edge of cereal and canola disease and fungicide resistance management in a 2-day GRDC-supported workshop, brought to you by the Australian Fungicide Resistance Extension Network (AFREN).
SDHI resistance in SFNB of barley discovered for the first time in Australia
Western Australian growers are urged to be on alert following the discovery of succinate dehydrogenase (SDHI, Group 7) resistance in spot form of net blotch (SFNB) in barley crops in the WA grainbelt.
Seeking grower and agronomist insights on fungicide resistance
The Australian Fungicide Resistance Extension Network (AFREN) wants to hear from grain growers and advisers to understand the level of knowledge they have when it comes to managing fungicide resistance.
Fungicide resistance a growing issue in barley disease
Barley growers are advised to monitor their crops for early signs of fungicide resistance, with research uncovering new developments in the resistance to fungicides in a common barley disease of the southern cropping region.
Webinars target fungicide resistance in crops
Grain growers will have the opportunity to improve their knowledge of fungicide resistance issues over coming weeks, thanks to a series of webinars being delivered by the Australian Fungicide Resistance Extension Network (AFREN).

SEPTORIA: Update on monitoring of septoria tritici resistance to fungicides
Tuesday 12 March
Brad Baxter (research officer – plant pathology, NSW DPI) and Nick Poole (Managing Director, FAR Australia) provide an update on monitoring for septoria tritici resistance to fungicides. STB is a persistent issue for wheat growers in the high and medium rainfall zones of the northern and southern grain growing regions. If left unmanaged STB can reduce yields by up to 50 per cent.

NET BLOTCH: Monitoring of net and spot form net blotch resistance to fungicides
Thursday 4 April
Dr Hari Dadu (research scientist, Agriculture Victoria) and Dr Tara Garrard (Sub-Program Leader Cereal Pathology, SARDI) provide an update on monitoring of net and spot form net blotch resistance to fungicides. Fungicide resistance in net blotch is widespread and it varies a lot. Hari and Tara outlined strategies for growers to consider to minimise resistance risks.
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.
