What’s the state of play of glyphosate?

Despite the overwhelming scientific consensus regarding glyphosate’s safety, the discussion is now infiltrating Australian communities and farmers are questioning what they would do if we lost glyphosate here. Professor Stephen Powles and Bayer Crop Science Head of Public Affairs Carissa Buckland (Matthew Cossey unfortunately couldn’t be with us this time) joined WeedSmart and AHRI Western Extension Agronomist Pete Newman to give an overview of the current situation surrounding the world’s most used herbicide and what this means for the Australian grains industry. If you missed the webinar, you can catch up above.

Weed control with automation

Someone who knows a lot about this topic is agriculture engineer and Kondinin Group’s R&D Manager Ben White. Ben joins WeedSmart’s Western Extension Agronomist Pete Newman to give a snapshot of the role automation will play in Australian agriculture, with a specific look at weed control. Ben provides examples of available technologies and outlines the horizon for automation in agriculture.

Controlling weeds in pulse crops in Western Canada

The success of pulse production, primarily lentil and field pea, in western Canada has led to some agronomic challenges. The most immediate being a proliferation of root rot diseases and the evolution of herbicide-resistant weeds. In this webinar, Eric Johnson, Research Officer, Weed Control Program at the University of Saskatchewan discusses Canada’s solutions to combat herbicide-resistant weeds with Paul McIntosh, AHRI’s northern extension agronomist. Four million hectares of pulse crops (lentil, dry pea, soybean, chickpea, fababean) is seeded annually in western Canada every year and contributes over $4 billion dollars to the province of Saskatchewan alone. Pulse crops in western Canada are highly reliant on Group B herbicides for weed control and resistance to these herbicides has evolved in a number of weed species. The most problematic of these Group B resistant weeds in pulse crops include kochia (Bassia scoparia), wild mustard (Sinapis arvensis) and false cleavers (Galium spurium). Identification of alternative mechanisms of action, primarily Groups G and K herbicides, and the use of PRE- plus POST- systems have provided solutions for weed control. This webinar will outline the research and will introduce the University of Saskatchewan’s recent work on integrated management of resistant weeds in pulses, led by Drs. Chris Willenborg and Steve Shirtilffe.

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.
