Farmers share their harvest weed seed control experiences with Planfarm Agronomist Dani Whyte

We have a special guest co-host this week, with Planfarm Agronomist Dani Whyte joining Jessica Strauss, providing insights on farmer interviews she conducted last harvest.

Dani has been working on a GRDC RCSN project, looking at harvest weed seed control practices in the Kwinana East port zone. She conducted 10 farmer interviews in total. In this podcast, we hear from three of the farmers who participated in the project.

The focus of this project is getting the weeds in the front of the header in low yielding crops.  The core messages are:

Harvest low – 10-15cm (this means paddocks need to be clean of rocks/stumps and staff need to be trained accordingly)
Coreflute attached to finger tyne reel
Knife extensions/crop lifters on the front of the harvester

Harvester set-up and implications of hay crossing borders

In the podcast this week, we’re focusing on harvester set-up and we also discuss how to capture weed seeds in the chaff fraction.

John Broster from Charles Sturt University gives us some insight into the research he and Michael Walsh (University of Sydney) did on capturing weed seeds.
A few years back, they measured how many weed seeds were entering the chaff fraction in a modern harvester. We learn what this means for growers.
We also hear from WA farmer Andrew Messina about setting up Case harvesters.
Finally, with the terrible drought conditions in Queensland and NSW, many farmers have had to source feed from totally different parts of the country. We chat with Grains Farm Biosecurity Officer for Biosecurity Queensland Kym McIntyre about the implications.

We also talked about a great opportunity being offered by the GRDC in the podcast. Did you know your group can apply for the GRDC “Grower Development Awards – Study Tours” to potentially help fund your trip to WeedSmart Week next year?
Applications close Oct 9. Get the details here.


Comparing the iHSD + Seed Terminator

Ben White joins us for the second webinar of our series “Chaff carts, sheep and seed destroying mills”!
Ben is an agricultural engineer and the Manager of Research and Development for the Kondinin Group. During harvest 2017 Ben visited a number of grain growers in WA who were using either the Seed Terminator or the integrated Harrington Seed Destructor.
Ben looked at all of the issues with these machines from fuel use, to power requirement, to reliability and more for a Farming Ahead Research Report. Ben shares what he learnt about the two machines and will discuss some of the strengths and weaknesses of each. You can watch the webinar in full below and you can read the Research Report in full here.


Chaff as Sheep Feed

What we missed for a long time though, was that the chaff dumps can be a great source of sheep feed. Ed Riggall is a WA-based consultant who specialises in livestock management and grazing systems. Ed’s passion is the integration of cropping with livestock which led him to investigate grazing chaff dumps as a source of sheep feed.
Ed has recently completed his second year of measuring the benefits to sheep of grazing chaff dumps from a range of crops and shares his knowledge on this research and how he has observed farmers adopting this practice in the south west of WA in the below webinar recording.


Use pre-ems to maximise winter crops in the South

Webinar Series: Pre-ems provide punch to prevent weeds
In our second webinar for our webinar series on pre-ems, we look at how hitting weeds before the crop phase provides many more shots at the weeds. Presenter Chris Preston, from the University of Adelaide, explains how to give your crop the best start and diminish the weed seedbank with pre-emergent herbicides. Chris delves into the behaviour of pre-emergent herbicides and what pre-emergents to use when sowing your crop dry in the south.
We get answers on…
What are the characteristics of the products and how should these influence use patterns?
How do you manage pre-emergent herbicides in different soil types?
Why don’t pre-emergent herbicides work as well on bromegrass as they do on annual ryegrass?
What is the current status of resistance to preemergent herbicides and how should this influence the way they are used?


Use pre-ems to maximise winter crops in the North

In our first webinar of this series, we ask Mark Congreve from ICAN Rural the question: why do things go wrong with pre-ems? Herbicide choice and farming system are factors to consider, with crop safety being top of mind. Mark takes us through the strategies to maximise pre-em performance particularly in relation to controlling ryegrass, wild oats, fleabane and sowthistle in the north and discusses how pre-ems breakdown and the implications on plantbacks and rotational crops. Scenarios in the northern region that lead to herbicide failure are discussed, as well as strategies to mitigate risk.


Disc seeding systems

Disc seeding systems combined with a stripper front have been a popular topic over the last few years. While It’s a bit more of an obscure system, there still is a lot of interest on the topic.
In this podcast, you’ll hear from Murry Scholz. He’s based in Henty, NSW and has a John Deere, with a disc seeder on 7.5” rows. He’s a mixed farmer and 2017 was his first year using the disc seeder.
You may already be familiar with the Hatty family as they hosted growers on their farm for WeedSmart Week in 2017 and have been featured in our podcasts and stories. In this podcast, Stephen Hatty gives us some insight into his disc seeding operation. Stephen is based in Matong, NSW and has an NDF disc on 10” rows, on heavy clay soils. Like Murray, 2017 was the first year he used the disc seeding system.

Spray wisely and well to maximise efficacy | Bill Gordon

In Webinar 2 from our Summer Spraying Series ‘Summer spray season challenges’, we hear from Spray Application Specialist, Bill Gordon.
Correct spray set-up and operation can guarantee efficacy, decontamination and reduce drift. The impact of managing a summer spray event effectively will have benefits to the crop, the neighbours and your ‘peace of mind’, knowing that drift or volatisation is minimised.
Hit play to hear Bill Gordon explain the risks involved and how to manage the spray event to ensure maximum efficacy.
Watch Webinar 1 ‘Effect of formulation and environment on dicamba volatility’ with Dr Tom Mueller here.


Effect of formulation and environment on dicamba volatility

In Webinar 1 from our two-part webinar series ‘Summer spray season challenges’, we hear from Dr Tom Mueller, from the University of Tennessee.
Post application of dicamba on triple stack GM crops has been a success for weed control of glyphosate-resistant weeds in the US, including Palmer amaranth. However, many adjacent areas were affected in 2016 (all illegal use) and 2017 (some illegal, mostly legal applications).
In the below webinar recording, Dr Tom Mueller presents the most recent findings on dicamba behaviour under field conditions and offers some parallels for Australian growers to consider with regard to 2,4-D behaviour and volatility. Check it out below!

HWSC Workshop overview and sowthistle management update

With the help of GRDC, Planfarm recently held Harvest Weed Seed Control (#HWSC) workshops in Western Australia. All the current approaches to HWSC were discussed in detail. In this podcast, Jessica Strauss is joined by two co-hosts, Peter Newman (AHRI, WeedSmart, Planfarm) and Nick McKenna (Planfarm) where they provide an overview of the learnings from the workshops. We hear from Goomalling farmer John Even who attended one of the workshops. He talks about his approach to weed control, including his reasoning behind choosing chaff lining as his primary HWSC management tool this season.


Rick Llewellyn describes the new Brome RIM

Brome grass has become one of the most costly grass weeds in many major grain growing regions. In conjunction with AHRI, CSIRO will shortly launch Brome RIM which can help growers develop the most profitable strategies for managing Brome grass populations.
RIM is a computer-based decision support system to aid farmers and agronomists in their weed management decisions. Rick and Pete put some potential practices to the test as they work through some realistic scenarios based on recent work with many farmers who are battling brome.
The results will show how the tool can inform practice change decisions and shed new light on some potential brome management combinations. You can also find out more about Brome RIM here.


Pulse crops provide extra punch against weeds

Pulses can be an important weed control tool, particularly when it comes to herbicide resistant annual ryegrass. In the past, pulses have had the reputation as the ‘weak link’ in crop rotations; however, evidence suggests pulses can provide a powerful punch in a weed control program.
Our webinar with AHRI’s Peter Newman puts University of Adelaide researcher, Peter Boutsalis in the ‘ring’ with Corrigin grain farmer Lance Turner to answer the question – how can you manipulate pulse crops to provide more hits on weeds?
Hitting weeds before, during and at the end of a pulse crop phase provides many more shots at the weeds. Pete Boutsalis and Lance Turner investigate the opportunity to diminish the weed seed bank using pulses and discuss the proven herbicidal and non-herbicidal tactics that target a broad spectrum of weeds in broadleaf crops. Lance will talk about his ‘6 hits on weeds in lupins’. How many hits can we really get at the weeds from one crop? Get your gloves on!
