Webinar Series: Summer spray season challengesWith the summer spray season kicking off, we aim to get our farmers using all the technology and knowledge available to them, to assist to keep spray drift and volatilisation controlled during summer spraying whether it be in regions where summer crops are grown or not. Correct preparation minimises drift and maximises efficacy. Choosing the correct nozzle for the job, adjuvant and weather is the first step, followed by careful attention to buffer zones, the speed of spraying and time of day. The first webinar of the series with Dr Tom Mueller from the US went off without a hitch. He talked about the rate and prevalence of volatilization under varied conditions and explored the problems that the US has experienced with dicamba on GM stacked crops and the ongoing consequences. We'll have this webinar up shortly for you to watch if you missed it! Don't forget to tune in for our last webinar of this series (and the year!) on November 21, when Pete asks Nufarm Spray Applications Specialist, Bill Gordon to step us through the process of setting up the spray rig correctly and assessing and choosing the conditions which will provide the best efficacy on the area being sprayed.

Effect of formulation and environment on dicamba volatility
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 from University of Tennessee 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.
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. Rick Llewellyn explains how it will work.
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.
Frost risk mitigation and growing a crop worth frosting
Webinar Series: Kick off early to get the edge on weeds 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 […]
Choosing optimum crop seed traits
Webinar Series: Kick off early to get the edge on weeds Webinar 1: Choosing optimum crop seed traits Along with choosing clean, large crop seed to promote early vigour, planting depth and time of planting are factors affecting crop competitiveness. NSW DPI’s Rohan Brill investigates the performance of open-pollinated and hybrid canola cultivars across varied […]
Resistance in corn, soybean & cotton crops in the US
Webinar Series: US and Australia share expertise to fight resistance 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 […]
Understanding P450s to better manage resistance
Webinar Series: US and Australia share expertise to fight resistance Webinar 1: Understanding P450s to better manage resistance In Part 1 of this webinar series, we look at P450s and understanding 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 […]
Strike weeds early in the north and prevent resistance
The Northern region is a glyphosate resistance hotspot! 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 […]
Non-herbicide tactics that fit in the Northern region
Non-herbicide tactics which fit in the Northern region are important to consider! 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 […]
Glyphosate resistance in ryegrass
AHRI’s Peter Newman asks Plant Science Consulting principal and University of Adelaide researcher, Dr Peter Boutsalis, to help us understand why plants surviving a glyphosate spray in the field aren’t always resistant.
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.
Increase pre-em efficacy through a mix and rotate strategy
We’ve done a good job of promoting herbicide rotation over the years. And whilst this advice still stands, recent research shows the benefits of mixing herbicides as well. As American weeds researcher, Pat Tranel, puts it, “rotating buys you time, mixing buys you shots (of herbicide)”. Listen to Pat and Pete as they explore the benefits of the mix and rotate strategy.
