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. If you’d like to catch up on this webinar, you can find it here.   Podcasts If you’d like to hear more on this topic, you can listen to our podcast with Garren Knell and farmer Gary Lang. Gary farms in a frost-prone area in Wickepin, Western Australia. To take a listen, click here. You can also listen to our podcast on spraying weeds and choosing seeds, which ties in with our Webinar on crop competition. We chat with Nufarm Australia Spray Application Specialist Bill Gordon. He gives some great tips and insights on correct set-up. Rohan Brill also joins us for insight on choosing canola seeds and the benefits of crop competition! Click here to listen.

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.   Podcasts You can hear more from Roberto Busi in the AHRI Snapshots podcast. He recently spoke about He recently spoke about his research and its implications on using pre-emergent herbicides. Timely advice for growers and agronomists out there!

Strike weeds early in the north and prevent resistance

Strike weeds early You’ve got to strike weeds early in the north to keep abreast of resistance. The northern region is a hotspot for glyphosate resistance with 8 of 12 species of weeds in the region having resistance and appearing mostly in patches. Department of Primary Industries NSW technical specialist Tony Cook explains the consequences of this. He explains how it’s imperative in the north to strike weeds early in fallow to control resistance.   The Northern region is a glyphosate resistance hotspot!

Non-herbicide tactics that fit in the Northern region

Queensland DAF weeds researchers Michael Widderick and Annie van der Meulen discuss the importance of non-herbicide tactics. In this webinar, they shine a light on herbicide resistance with new research from the Northern region (Qld and NSW). They also examine the tools that can be used, other than herbicides, to combat weeds in the north.   Bulletin Board Michael Widderick also has been interviewed on this topic for our Bulletin Board. Diversity in cropping systems and diversity in weeds in the northern GRDC grains region of NSW and Queensland calls for diversity in weed management! Those solutions include non-herbicide tactics. Survey work in the region has identified more than 70 different weed species that impact on grain production. More than 10% of these weed species has confirmed populations within Australia that are resistant to glyphosate and several other chemical modes of action (MOA). Read the post in full here.

Glyphosate resistance in ryegrass

The magnifying glass is put to glyphosate resistance in ryegrass in this webinar! AHRI’s Peter Newman hosts the webinar with presenter Plant Science Consulting principle and University of Adelaide researcher, Dr Peter Boutsalis. Peter helps us understand why plants surviving a glyphosate spray in the field aren’t always resistant. Resources Plant Science Consulting (resistance testing) Article: Don’t jeopardise glyphosate for clean fencelines Australian Glyphosate Sustainability Working Group   Q & A Timestamps 22:06 I thought Dave Minkey did some work and showed 8L/ha of glyphosate didn’t kill ryegrass, but weren’t resistant, and it was due to the waxy leaf from early water stress? 23:36 Should we eradicate brome populations (glyphosate resistant brome populations) when we find them? (Taking a biosecurity approach and treating it like a noxious weed?) [AUDIENCE POLL] 28:03 What is the ideal water rate to spray glyphosate on ryegrass? 30:03 Does spray topping for seed set control of glyphosate resistant ryegrass or brome grass work considering that it’s sequestration at the tip e.g. does it go to the seed head? 31:52 Does dust from tractors in dry fallow neutralise glyphosate? E.g. for waxy leaves? 32:15 What about the use of adjuvants to improve the efficacy of glyphosate? 53:42 What is the optimum time to come back and double knock firebreaks? 56:37 In a Roundup Ready crop, would you prefer two applications of 1L/ha four weeks apart, or a single application of 2L/ha? 57:42 Spraying glyphosate at night in the cool verses spraying during the day? 58:54 Alliance (paraquat and amitrole) being good on fencelines? 59:49 On the label for UltraMax it talks about using a coarse to very coarse spray quality. Are coarse droplets too big to hit small ryegrass?

Emerging trends

New technologies in agriculture don’t come around too often… but new weed threats seem to! AHRI’s Peter Newman joins the unforgettable inventor and farmer Ray Harrington, accompanied by Devon Gilmour of McIntosh & Son, to talk about the opportunities and challenges of incorporating the iHSD into Australia’s cropping systems.   Resources www.ihsd.com Webinar recording: Setting up your header for harvest weed seed control AHRI insight: The integrated Harrington Seed Destructor has arrived AHRI insight: Harvester setup with Ray Harrington Q&A Timestamps 18:30 How does capacity go in canola where there is more bulk with potentially oily chaff? 22:10 How many hours is the cage expected to last? Is there a price list available on wearing parts? 24:55 Is there any issue with fire danger? 25:32 How will they fit to a New Holland? Is mechanical drive an option? 27:04 I can understand the flow of the counter rotating mill, but what effect is the stator on moist chaff with flow and blockage? 27:55 How do you judge grain loss, if everything is milled? 30:02 If the mills wear uneven, will they go out of balance? 31:20 How wide will it spread product? 58:16 What L of oil per minute of oil flow is needed?
