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...

Fungicide resistance in the north

by Professor Levente Kiss

Growers in the north could consider fungicide resistance less of a threat than growers in the south and west, however there is no room for complacency.

As Professor Levente Kiss from the University of Southern Queensland’s Centre for Crop Health points out in this podcast, as long as there are fungal crop diseases there is a risk of fungal resistance. Barley, wheat and pulses can all be affected.

Northern growers need to appreciate the importance of rotating and mixing fungicides, including as seed treatments, in order not to encourage fungicide resistance in important diseases such as barley net blotches, mung bean powdery mildew, wheat powdery mildew and septoria tritici blotch.

South Australian grain growers have been alerted to several cases of fungicide resistance in recent growing seasons, including in net form net blotch of barley, and wheat powdery mildew.

In this podcast, Dr Hugh Wallwork, from the South Australian Research and Development Institute, the Department of Primary Industries and Regions’ research division, talks about the factors that contribute to fungicide resistance and how fungicide management needs to begin with variety and seed treatment selection before sowing.

He explains that growers should be using all available agronomic practices to reduce disease pressure and should avoid repeat applications of a single fungicide active or chemical Mode of Action. This will help protect the effectiveness and availability of their essential fungicide controls.

In Western Australia, outbreaks of fungicide resistance have occurred in several important diseases of barley. Resistance is a significant but preventable problem that can largely be managed by taking care not to repeatedly expose a pathogen to the same product or chemical Mode of Action Group.

It is important for growers to recognise that this management regime can include fungicide seed treatments and in-furrow fungicide applications, as well as foliar sprays later in the season. Fungicide rotations to manage and prevent fungicide resistance need to take all of these applications into account.

Geoff Thomas, plant pathologist from the Department of Primary Industries and Regional Development WA, discusses the importance of using an integrated disease management program to reduce disease pressure and manage fungicide use and resistance in WA cropping systems.

Fungicide Resistance Five podcast series

The ‘Fungicide Resistance Five’ is the basis for an integrated disease management strategy that growers can use on-farm to reduce fungicide resistance pressure on crop pathogens.

This six-part podcast series, produced through the Australian Fungicide Resistance Extension Network (AFREN), unpacks the individual elements of the strategy to inform growers why and how they should minimise the risk of fungicide resistance developing in their paddocks.

AFREN is a significant GRDC investment that brings together a national network of regional plant pathologists, fungicide resistance experts and communications and extension specialists. It is co-ordinated through the Centre for Crop Disease Management (CCDM), a co-investment between the GRDC and Curtin University.

Dr Kylie Ireland, first Extension Coordinator of Australian Fungicide Resistance Extension Network (AFREN), discusses how fungicide resistance occurs, its potential impact on crop production, and how the Fungicide Resistance Five can help growers mitigate their risk.

How does variety selection help slow fungicide resistance? Dr Grant Hollaway points out how planting crop varieties with genetic resistance to frequently occurring diseases can reduce disease pressure and an unhealthy reliance on fungicides.

Long-practiced crop rotations are an effective non-chemical means of reducing (or even eliminating) soil and stubble borne fungal pathogens in paddocks. DPIRD plant pathologist Geoff Thomas discusses the continued importance of practicing crop rotation for disease control.

South Australian plant pathologist Dr Tara Garrard covers the range of agronomic practices growers have at their disposal to reduce disease pressure, limit fungicide applications and lower the risk of promoting fungicide resistance in their crops.

Non-chemical strategies to reduce disease pressure

by Dr Tara Garrard | The FR Five

Fungicides remain a valuable and powerful tool for managing crop disease and FAR Australia Managing Director Nick Poole explains how to identify the right times to apply fungicide for maximum effect and economic benefit.

Using fungicide mixtures and rotating Mode of Action groups is vital to eliminate resistant pathogen strains. Fungicide resistance specialist Dr Fran Lopez Ruiz from the Centre for Crop Disease Management at Curtin University highlights the importance of a dynamic spray program.

SDHI resistance in barley net blotches

Succinate dehydrogenase inhibitors, or SDHIs, are some of the most effective chemistries to grace the market in recent years for the management of net blotches in barley. The problem is, they are already under strain in the Southern and Western Regions.

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 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).

"Coupling the field expertise of up to 20 leading agronomists with the fire-power of Nick Poole, Steve Marcroft, Fran Lopez-Ruiz and expert plant pathologists from each region, these discussions 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," workshop facilitator John Cameron said.

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 in cereal and canola 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
