Ground Cover Supplement, January-February 2024

GRDC has invested in the Australian Fungicide Resistance Extension Network (AFREN) since 2019, led by Associate Professor Fran Lopez-Ruiz of Curtin University.  This Groundcover Supplement showcases the achievements of AFREN thus far and shines a spotlight on new fungicide-related research underway at Curtin University’s Centre for Crop Disease Management (CCDM).

Knowledge is power when managing fungicide resistance in pulses

Knowledge is power when managing fungicide resistance in pulses

Australian pulse production is threatened by the risk of fungicide resistance. Most crop species are susceptible to one or more fungal diseases and although breeding has developed some resistant varieties, there are still susceptible varieties grown which require more-frequent fungicide applications.

Fungicide resistance in Queensland: be alert

When the first map of fungicide resistance cases in Australia was compiled in 2016 by the research team at Curtin University’s Centre for Crop and Disease Management (CCDM), led by Associate Professor Fran Lopez-Ruiz, Queensland remained a blank region on that map.

Preserving our fungicides

Fungicides belong to a range of essential crop protectant tools that also include insecticides and herbicides. Fungicides can be classified as contact or systemic. Contact fungicides remain on the plant’s surface and are also referred to as protectant or preventative...

Curbing the rise of fungicide resistance

The ‘Green Revolution’ and introduction of fungicides, while contributing to a pivotal advancement in grain production, is not without its challenges, foremost among them being the looming threat of fungicide resistance.

You’ve got to keep it complicated

Most of us would agree with the advertising Meerkat when he advocates making life “simples”. Simple is good. Simple is usually better. But, sometimes it’s good to be complicated, especially when it comes to preventing and managing fungicide resistance. How so?...

How does fungicide resistance develop?

Fungicide resistance is all about selection pressure. Every time a fungicide is applied, we apply selection pressure to the fungal population(s) present in the crop. It’s important to know – it’s a numbers game. More fungicide applications equals more opportunities...

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

A number of fact sheets on individual crops, diseases and specific resistance cases have been developed and are available via the AFREN and GRDC websites.

Two general fact sheets – on Fungicides in Australia and How Fungicide Resistance Develops – have also been produced.

Webinars

A total of ten webinars have been delivered in 2020 and 2021 to provide seasonal updates on diseases pressures and fungicide issues. These were regional and featured key AFREN presenters. Recordings of these webinars have been published to the AFREN website.

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

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

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

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

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).

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) will 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) will 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 will outline 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.auor fill in the online registration form.
