    SDHI resistance in South Australia

    SDHI Resistance in South Australia

    Did you hear about the fungicide resistance discovery in the Yorke Peninsula last year?

    Net form net blotch (NFNB) of barley was declared fungicide resistant to the SDHI fungicide fluxapyroxad.

    In this episode, CCDM fungicide resistance researcher Fran Lopez-Ruiz joins Megan Jones as they discuss the situation, talking about why it happened, how to manage it, and how this can be prevented in other Australian regions.

    First up they talk to Central Ag Solutions agronomist Sam Holmes who was the first to notice an issue with fungicide control and to alert SARDI. Sam talks about the factors that likely led to the resistance problem, including barley on barley rotation, the same variety grown throughout the region, and early sowing.

    Next they talk to Tara Garrard, SARDI cereals pathologist who advises on the best way to manage resistance in the region, by avoiding SDHI fungicides, avoiding the more susceptible varieties, and avoiding a barley on barley rotation.

    In the podcast Fran comments further on the fungicide resistance discovery, and why Australian growers are at higher risk of developing resistance, due to the larger paddock sizes, the limited modes of actions that are available and also the tighter rotations of the same variety.

    Fungicide resistance findings from a grower cohort of the WA grainbelt

    Fungicide resistance findings from a grower cohort of the WA grainbelt

    With 330 samples sent in during the 2019 season from 173 farmers, net blotch resistance in the South of the WA grainbelt is now less of a mystery.

    In the next Crop Disease Podcast, CCDM Director Mark Gibberd joins Megan Jones as they discuss the results from the Barley Disease Cohort Project, where about 15 per cent of samples carried the mutation associated with fungicide resistance – CYP51A F489L – which were widespread throughout the grainbelt.

    First up they talk to Grass Patch farmer Dan Sanderson, who sent in a few barley leaves in September last year, and received a negative result for the mutation. Dan talks about his disease management strategies and how the result will help him manage disease going forward.

    Next they talk to Chris Robinson, a Farmanco Agronomist based in Kojonup, to hear his take on the results and what his clients will do differently this season, including the application of an SDHI fungicide to the program if needed.

    Mark then finishes with some key recommendations for managing net blotch resistance, and the next steps for the project, which aims to provide economical, regionally relevant advice for growers managing fungicide resistance.

    Preparing for 2020 following drought or a dry year

    Preparing for 2020 following drought or a dry year

    How is your 2020 season plan shaping up to be? In this episode CCDM farming systems economist Amir Abadi once again joins Megan Jones as they prepare growers for disease management in 2020, particularly for those who are coming from a drought or drier year.

    First up they talk to producer Ben Webb from Kojonup, WA, who has a mixed sheep and cropping enterprise, growing canola, wheat, oats, lupins, faba beans and vetches. Ben talks about his plans for the upcoming season, following on from a drier season in 2019, and the importance of rotation in driving down crop disease issues.

    Next they talk to Steven Simpfendorfer, who is a cereals pathologist from NSW DPI based in Tamworth. Steven talks about the dry conditions in the Northern and Central NSW regions, and how growers can maximise their chances of being profitable this season by considering their disease management.

    Finally Amir talks about the importance of fungicide timing and linking this to the weather, as well as strategies around spraying preventatively versus curatively.

    The top disease management strategies of 2019

    The top disease management strategies of 2019

    The year 2019 may not have been the best for most growers around Australia, but with the ‘not so good’ growing conditions, comes a silver lining. Crop diseases held back, giving them a break from an expensive fungicide program.

    In this episode CCDM director Mark Gibberd once again joins Megan Jones as they discuss last season, and the strategies growers are using to manage disease.
    First up they talk to Geoff Thomas, DPIRD plant pathologist about his take on the 2019 season for WA growers. Geoff talks about the way growers are increasingly becoming more tactical when managing disease.

    They also talk to Nick Poole, FAR Australia managing director, who discusses the high rainfall zones of South Australia, Victoria and Tasmania, and how growers are seeing a resurgence in septoria tritici blotch. Nick also talks about the difficulties in managing this disease.

    Finally, Mark ends the podcast with summarising the top 4 strategies for 2019: resistant varieties, crop rotation, fungicide timing, and fungicide rotation.

    Managing stubble in different rainfall zones, and how we differ from East to West.

    Managing stubble in different rainfall zones, and how we differ from East to West.

    Harvest. It’s upon us again. But as you dust off the big machine, have you thought about how you will manage your stubble this season?

    In this episode CCDM’s farming systems economist Amir Abadi once again joins Megan Jones as they discuss how to best manage stubble in different parts of the country.

    First up they talk to Cassandra Schefe, research coordinator from the Riverine Plains Farming Group about their five-year research trial into retaining stubble and the effect on yield.

    They also talk to Garren Knell, WA consultant from ConsultAg based in Narrogin, who talks about research looking at barley on barley rotations in the mid rainfall zone, and how stubble management can help reduce disease load going into the following season.

    Garren also talks about the importance of integrated disease management, and Amir finishes off with a roundup of how growers can economically reduce their disease risk – simply by protecting that flag leaf.

    How to know if you have fungicide resistance

    How to know if you have fungicide resistance

    Have you checked your crop lately and thought that last spray should have worked better? It’s possible you might have fungicide resistance. But what does fungicide resistance look like, and how can you tell you have it?

    In this episode CCDM’s fungicide resistance expert Fran Lopez-Ruiz once again joins Megan Jones as they discuss how to know if you have resistance in your paddock, and what to do about it.

    First up they talk to Brent Pritchard, a well-known WA agronomist from Farmanco, Albany, who has seen fungicide resistance identified in his area since the first case of barley powdery mildew back in 2010. Brent talks about how growers are noticing more cases of fungicide resistant net blotch in their area, and how industry can work to reduce it.

    They also talk to Angela Van de Wouw, a canola blackleg expert from the University of Melbourne, who talks about how her team are working to develop solutions for growers managing resistant blackleg on their properties. You can also view a video on her work here: https://www.youtube.com/watch?v=egR38M1CBGw

    Brent mentions the CCDM Barley Disease Cohort Project. More information on that project here: www.ccdm.com.au/cohortproject
