Our webinars bring you the latest on-farm strategies farmers and agronomists are using to manage weed numbers in broadacre crops. Anywhere you have an internet connection, on a smartphone or computer, you can register and join us for one of our regular webinar series.


Management of Feathertop Rhodes grass & Barnyard grass

We can only hope we’re close to the end of a long dry spell and we’ll soon see a break! And when we do, significant rain will see a massive flush of weeds. What will particularly be problematic is grass weeds – Feathertop Rhodes grass, Barnyard grass, Sweet summer grass and Urochloa (liverseed grass).
In this webinar, we hear from Bhagirath Chauhan (pictured above), QAAFI weeds researcher, and Paul McIntosh, WeedSmart’s northern extension agronomist.
They investigate the best strategies to ensure summer crops and the upcoming winter crop are given the resources to achieve higher yields. Controlling summer grass weeds requires a strategy with interventions at various stages of the growing season.
Bhagirath explains the biology of the most problematic grass weeds and how to employ strategies that provide your summer crop and subsequent winter crop with ideal conditions for growth.


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.

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.


Pre-em Herbicides 101 Q&A Forum

This webinar is a Q&A for our new Diversity Era course, “Pre-emergent Herbicides 101”. You can sign-up and do the course for free here.


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

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.
