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.

Fungicide resistance in the south
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.

Fungicide resistance in the north
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.

Fungicide resistance in the west
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.

Measuring the impact of disease on yield
Some ground breaking research has resulted in a breakthrough for growers and agronomists wanting to measure the potential impact of disease on yield. A national network of trials over five years will result in a new ability to quickly and accurately assess potential disease impact on some of the more popular cereal varieties. On this podcast we look at the results of that research and also how it all came about and salute the hard work of the many agronomists, scientists and biometricians involved.

Stripper fronts – time saving, fuel saving and ...
Farmers across the Western Region are using a variety of stubble strategies to protect soil moisture over summer and to protect those soils from harsh winds. Noel Keding has taken stubble strategies to the next level using a stripper front on his cereals. Noel has some experience using stripper fronts in both low and higher rainfall environments, so his experience may help other growers who are wondering whether stripper fronts might be an option. On this podcast Noel talks about the advantages of using stripper fronts in his experience including significantly greater harvest efficiency but also some of the challenges such as getting the crop germinated and out of the ground because of the extra shading from the straw.

Eroded top soil
Losing just one millimetre of topsoil in a wind erosion event can result in significant changes to soil fertility and cause yield losses in subsequent crops of up to six per cent. But there are some measures growers can take to protect their topsoil and reduce the impact of severe wind. In this podcast, Cropfacts consultant Harm van Rees, Agronomy Solutions director Sean Mason and South Australian Department of Primary Industries and Regions consultant Mary-Anne Young join in a discussion on dealing with the effects of wind erosion via ongoing soil management or tactics when multiple dry seasons have ruled out other options.

Accessing trial data – It’s never been easier
Online Farm Trials (OFT) is a website that contains a wealth of cropping data from the nation’s leading research organisations, and it’s proving to be an invaluable resource for both growers and researchers alike. This podcast shares how growers can use the platform to make informed management decisions, and how research organisations can benefit from getting involved and contributing trial information. This podcast features Federation University OFT project lead Nathan Robinson, GRDC emerging technologies officer John Rivers and Denielle Smith from Northern Growers Alliance. The OFT platform is a GRDC and Centre for eResearch and Digital Innovation collaboration.

Plant available water capacity
Plant Available Water, is key to determining potential crop yield. It’s also the basis for sowing decisions and fertiliser applications. Many things affect how much stored soil water is available, rainfall before and during the growing season, infiltration, evaporation and transpiration. And then there’s Plant Available Water Capacity, which is the total amount of water a soil can store and release to a crop which differs depending on the crop.

Foliar diseases are a major constraint to profitable barley production across Australia, affecting both yield and quality. In this podcast, senior plant pathologist Dr. Lisle Snyman from the Department of Agriculture and Fisheries Queensland discusses the presence and spread of barley foliar pathogens across Australia's growing regions. Dr Snyman was part of the barley foliar pathogen project. The four-year GRDC investment successfully characterised major barley pathogens in Australia and identified effective resistance genes from around the world. Part two of this podcast focuses on a new three-year research initiative that is leveraging the findings from this completed research, by progressing the most promising NFNB, SFNB and scald resistance genes for use in Australian breeding programs.

Dr Kai Voss-Fels is the project lead and senior research fellow with the Queensland Alliance for Agriculture and Food Innovation, based at the University of Queensland in Brisbane. The program is off to a strong start, thanks to the findings from the four-year barley foliar pathogen project.

Growers are set to get better variety recommendations faster through a new GRDC investment, INVITA, which is adding value to the National Variety Trial (NVT) program. The investment is led by Prof Scott Chapman from the University of Queensland (UQ) which is working in collaboration with Australian partner, CSIRO. The investment, INVITA, leverages off a major EU investment INVITE (Innovations in plant Variety Testing in Europe), a consortium led by INRA in France (INRA being the French equivalent of CSIRO). The main INVITE collaborator with INVITA is Prof Fred van Eeuwijk, a statistician from Wageningen University and Research (WUR), the world's number one agricultural university.
