Weed seeds and herbicide resistant genes have the potential to move across farm boundaries and between different land uses. A collaborative project, called area wide management for cropping systems weeds, is taking a unique approach to traditional weed control by collaborating beyond fence lines with varying land users across three pilot regions - the Sunraysia, the Darling Downs and the Murrumbidgee irrigation area. In this podcast, we hear from CSIRO's Dr Rick Llewellyn, and Mallee Sustainable...

Perth Update Event 2022 – Dr. Mike Ashworth The cost of constantly evolving weed infestations in Australia is staggering. Growers spend around $2.5 billion every year on the problem, with annual ryegrass the number one ranking Australian cropping system weed. In WA, a series of trials over several years has been studying the interaction between wheat seeding timing and pre emergent herbicides choice on annual ryegrass seed production, with some helpful results on offer. In this podcast, we talk ...

Grain storage is a long-term investment so it’s important to get it right from the start. Considerations need to include storage design and structural integrity, effective pressure testing and knowing how to seal silos correctly to achieve successful fumigation.

It’s an unusual thing to see – a mob of cattle grazing contentedly in a patch of paddock, held there by an invisible border. But virtual fencing technology is really taking offand is showing promise as a tool to help mixed farmers control weeds.

Nick Poole from FAR Australia provides an excellent explanation of how to target fungicide applications for the best economic return. He describes the value of focusing on critical growth stages and their ‘money leaves’, the best way to manage disease risk in crops before tillering, and the importance of protecting fungicide effectiveness for the long term.

It’s been common practise across the southern grain growing region to wait for opening rains, before applying a knockdown herbicide, then seeding the crop. But new research is revealing weedsare better controlled by adopting a three-pronged approach of sowing early, at a high density crop seeding rate while also applying an efficient herbicide. As the University of Adelaide’s Dr Gurjeet Gill and Ben Fleet explain, the mid-trial results come from a five-year GRDC investment looking into weed mana...

While farmers typically spray fungicide to manage one disease, applications should be considered in a broader context. Dr Steven Simpfendorfer describes how spraying one pathogen can inadvertently encourage resistance in other pathogens that may be present. He outlines some typical examples, including rusts and powdery mildew in wheat; blackleg and sclerotinia in canola; as well as net blotches and powdery mildew in barley.

In Western Australia’s South West agricultural zone there are 3 million hectares of lateritic gravels or ironstone gravel soils. These are sandy soils that have a cemented laterite surface or caprock. Many growers are using contractors with specialised machinery that rips and pulverises this top-layer, making sowing easier and improving the likelihood of good crop establishment. What is also needed for developing crops is good nutrition and Lateritic soils bind-up phosphorus, an essential nutrie...

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 rot...

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 s...
