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.


Weather forecast accuracy and crop competition trial results

This week on the podcast, we look into how to utilise weather forecasts and get the latest information on crop competition trials conducted by YP AG.

Agriculture Victoria Seasonal Risk Agronomist Dale Grey provides an excellent overview of what weather forecasts to take seriously and those which you should probably take with a grain of salt. Dale has a real knack for simplifying this complicated topic, so if you want to get a good overview of the weather, he’s your man!
Dale refers to no breaking rains yet in the interview but since the interview, there have been some breaking rains across parts of southeast Australia. You can check out the latest map for May rain thus far here. Also on related climate topics, the ‘Climatedogs’  🐶 🦴 animations (key climate drivers) were updated for a national audience recently and you can check them out here. And if you’d like to keep up-to-date with all of Dale’s weather forecasting, you can simply hit a button to subscribe to The Break here.
We’re also excited to have Agriservices Agronomist Chris Davey (pictured up top) on this podcast talking about crop competition at seeding time. Chris is based in Kadina, South Australia and he recently wrote a great article in YP AG’s agronomy newsletter, where he said ‘weed seed reduction starts at seeding’. There are multiple benefits of crop competition, including increasing crop yield in weedy situations, reducing weed seed set, and improving the efficacy of Harvest Weed Seed Control. Chris has kindly given us access to his article if you’d like to refer back to it after the interview on the results from YP AG’s recent trials and some tips on crop competition. You can download it here. You can find out more about YP AG 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.
