Stop the drift – spray drift tips with Mary O’Brien

In this webinar, we hear from Mary O’Brien, a consultant with extensive experience in managing spray drift and Paul McIntosh, AHRI’s northern extension agronomist, as they discuss the strategies to minimise spray drift and why it matters. When it comes to minimising spray drift, you need to: Be aware of the signals Understand the characteristics and volatility of the herbicide Assess your spray nozzles Further links GRDC Spray Drift Webinar GRDC Spray Application Manual GRDC – Reducing herbicide damage APVMA Advice

Harvester set up for harvest weed seed control (HWSC) for all header colours

For many years we have focused on the different HWSC tools on the back of the harvester and what has become very apparent is the need to set up the harvester to ensure that the vast majority of weed seeds enter the HWSC tool. In this webinar, WeedSmart Agronomist Peter Newman and Ray Harrington discuss the four stages of HWSC: 1. Get weed seeds in the front of the harvester 2. Get weed seeds out of the rotor – concaves/rotor speed 3. Keep weed seeds in the chaff stream – wind/baffles 4. Put weed seeds into one of the six HWSC tools We also discuss how to set up a range of machines to maximise weed seed capture.

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?   Music: bensound.com

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.   Music: bensound.com

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.

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!   You can listen to Webinar 2 from the Summer Spraying Series, “Spray wisely and well to maximise efficacy”, with Spray Application Specialist, Bill Gordon, here.

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.
