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.

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!

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!

Frost risk mitigation and growing a crop worth frosting

Webinar 2: Frost mitigation
Frost is devastating and unfortunately, more frequent events are predicted to occur right up until 2030.
So, what can you do about it?
Webinar 2 of our series, Growing a crop worth frosting, addresses how climate change means more weather events like experienced in 2016, will continue to impact crops.
Therefore, mitigating the risks is becoming more important, especially in frost-prone areas like those in the southern part of Western Australia.
Correct early crop sowing strategies can be unravelled by a frost event later in the season. Early sowing is a proven strategy which can be used to minimise the weed burden and maximise crop yield.
The question remains on how to manage the risk?
You can watch the below webinar for insights into how you can grow a crop worth frosting.
Ben Biddulph and Garren Knell explain the risks and how to minimise the downside of a frost event without delaying planting.
 
Webinar 1: Choosing optimum crop seed traits
The first part of this series was Webinar 1: Choosing optimum crop seed traits.
NSW DPI’s Rohan Brill investigates the performance of open-pollinated and hybrid canola cultivars across varied cropping environments. He discusses how choosing the right seed traits and early planting can increase yield and maintain pressure on weeds.
Along with choosing clean, large crop seed to promote early vigour, planting depth and time of planting are factors affecting crop competitiveness.

Resistance in corn, soybean & cotton crops in the US

Webinar 2: Resistance in corn, soybean & cotton
Part 2 of our Webinar Series: America and Australia share expertise to fight resistance, looks at resistance in corn, soybean and cotton.
It features special guest US Professor Jason Norsworthy.
Peter Newman asks Jason if the US is thinking about alternatives to glyphosate.
Given their high dependence on RR crops, what are the repercussions of this strategy?
Jason is evangelical in his quest to keep glyphosate working for corn, soybean and corn, soybean and cotton crops.
What are the challenges and the strategies being used to address creeping resistance?
You can watch the webinar below to find out!
 
Webinar 1: Understanding P450s to better manage resistance
In Part 1 of this webinar series, we look at how to understand how plants evolve resistance to a herbicide that has not yet been used.
Colorado State University researcher, Todd Gaines and AHRI’s Roberto Busi are the presenters on this webinar.
Host Peter Newman also asks the presenters what the genetic basis of metabolic resistance is and can we control metabolic resistant weeds?
Todd explains the science with Roberto Busi outlining new results on interactions between an insecticide and current pre-emergent herbicides to control ryegrass.
