WeedSmart in HRZ – practical options for dealing with ryegrass

Effective ryegrass control is becoming increasingly difficult in High Rainfall Zone farming
This webinar is designed to help growers and agronomists explore farming system-
based options to manage annual ryegrass populations in our cropping areas.
Grassroots Agronomy’s Greg Condon is a leading agronomist from Southern NSW, involved with the GRDC’s National WeedSmart project, which focuses on ‘the farmer calling the shots, not the weeds’. Greg will present options, (not just chemical) which HRZ growers could integrate into their farming systems to help manage difficult-to-control weeds.
This webinar is brought to you by Southern Farming Systems and the Grains Research Development Corporation and presented by WeedSmart.


The future of chemical use in farming with Mark Congreve

Join WeedSmart’s Paul McIntosh and Shannen Barrett as they host ICAN’s Mark Congreve who discusses the future of chemical use in farming including market drivers, herbicide discovery, automation, future for glyphosate & paraquat and much more!


Crop Competition Q&A

Dr Gurjeet Gill & Dr Michael Widderick answer questions that may have cropped up for participants of Crop Competition 101.
They also provide a broader overview of the crop competition work being delivered by their respective teams.

What’s the cost of HWSC for you? With WeedSmart’s Peter Newman

It depends… on crop type, yield, area, number of harvesters and so on.
The costs of harvest weed seed control (HWSC) tools have been calculated using best estimates to calculate the effect on yield and crop area and are limited to cereal crops.
Pete Newman, WeedSmart Western Extension Agronomist has developed this interactive model and will step you through the benefits of different strategies and how to use the HWSC cost estimate tool to measure the impact to your cropping program.


What’s next in broadacre weed control – is green on green a reality? With Greg Condon

In this webinar, WeedSmart Southern Extension Agronomist Greg Condon (pictured above) discusses weed control techniques especially using site-specific technology and how these are evolving.
Site-specific weed control covers a wide range of tactics from chaff lining to shielded spraying, optical spot spraying and the emerging tech around green on green.

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.

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.
