How do I make the right decision on using Group Gs?

Choosing and applying the right pre-emergent herbicide can be difficult, particularly if herbicide resistance is becoming a challenge in a no-till system. Join Dr Chris Preston, University of Adelaide (UA) professor weed management and WeedSmart’s Chris Davey as they explain the new Group G chemistry and de-mystifies which Group G works best for winter cropping systems.

US weed control group GROW joins forces with WeedSmart and our pre-harvest guide

Our South Australian-based Southern Extension Agronomist, Chris Davey joins us to give us the rundown on what growers need to be thinking about before harvest kicks off.
We also catch up with GROW advocate, Virginia Tech Associate Professor and Extension Weed Science Specialist, Michael Flessner about the new partnership between WeedSmart and GROW. GROW stands for Getting Rid of Weeds and is a publicly led network coordinating research and outreach, providing science-based information and decision support tools to make agriculture more sustainable and precise.

Regional Update – Andrew Storrie, WA, on controlling caltrop

Growers in the Esperance port zone recently raised the issue of caltrop weed in their region at a recent grower network member meeting.
So, today on the Regional Update, agronomist Andrew Storrie, who is also known as “Agronomo” will talk to us about how to best control this weed.

What matters more? Crop sequence or seeder?

Why were the batsmen tampering with the ball, shouldn’t that be the bowler’s job?
These are all questions that were being asked by a local project committee of growers and advisers, and there was only one way to answer them.
Enter Tony Swan from CSIRO. He and his team embarked on a massive, long-term research effort in Temora NSW, working with FarmLink Research to make it happen. The trial ran from 2014 to 2017 and the preliminary results are in.
And the winner is…
DIVERSITY. (Insert a fist pump from Professor Steve Powles here!)
Diverse crop rotations, including a double break, premium herbicides, with some extra crop competition courtesy of barley thrown in, and we have a winner. This diverse crop rotation smashed ryegrass numbers down from 1864 plants/m2 to 145 plants/m2 in just three years, and it was also the most profitable rotation.

Double breaks – a double shot at annual ryegrass

Perhaps you’re a ‘short black’ wheat-canola type, strong on inputs?
Or a ‘long black’ type who likes to dilute their rotations a bit more?
Or are you a ‘double shot’, throwing in a few break crops in a row for maximum effect?
When it comes to managing annual ryegrass populations, Tony Swan and the research team from CSIRO Plant Industry and FarmLink, have shown that ‘double shots’ are the key. Growing two break crops in sequence (broadleaf crop, hay crop or long fallow) was more effective in reducing resistant ryegrass numbers to manageable levels than a single break crop or continuous wheat over a three-year rotation.
And it can still be profitable.

RIM: Ryegrass Integrated Management

RIM is a hands on, user-friendly decision support software that allows farmers and advisors to evaluate the long-term cropping profitability of strategic and tactical ryegrass control methods, on the long-term and at the paddock scale. RIM lets you test your ideas: How can you run your ryegrass down and profit up? New rotation? New technique?

Single Shot drone weed mapping technology and CBH’s new approach to maximum residue limits

CBH Group Agronomist, Steven Tilbrook, will join us to discuss how they’re addressing maximum residue limits.
We also will be hearing from John, Tony, and Ben Single about their air-borne weed sensor, Single Shot. This weed sensor rapidly detects and maps weeds. Ben Single describes how he saw the benefits of separating the weed detection and weed spraying tasks and set about building the platform, working with Newcastle-based company, Robotic Systems to make the idea a reality.
On the podcast, we also mentioned we’ve got some great new content for you to check out.
If you’d like to find out more about Single Shot, you can read an article we did on it here.
We’ve got a new “Ask an Expert” article with University of Adelaide weeds research and PhD candidate, Alicia Merriam. She answers the question “Where to next in controlling herbicide resistant broadleaf weeds in IMI-tolerant lentils?: You can find the answer here.
We’ve also got a new article on stacking the odds against awnless barnyard grass. Check it out here.

The unsung hero – crop competition

We don’t want to give the weeds a free kick by growing un-competitive crops. Crop competition with weeds is a double-edged sword. There is the effect of the weeds on the crop, and the effect of the crop on the weeds. A competitive crop will suffer less yield loss at the hands of the weeds, and will also reduce seed set of the weeds compared to an un-competitive crop. In other words more crop, fewer weeds.
In this week’s podcast, AHRI Extension Agronomist Greg Condon and AgriVision Agronomy Consultant Matt Bissett (pictured) provide excellent overviews on the different crop competition approaches that can be employed.
There are six main aspects of crop competition:
1. Seed rate
2. Row spacing
3. Orientation (north-south vs. east-west)
4. Crop variety/species
5. Soil health
6. Time of sowing – early sowing is usually best
It’s hard to get all of the six points above right, and growers need not aspire to practising all six of these competition factors, but they can use a range of these practices to ensure that their crops have a fighting chance against the weeds.
Crop Competition is one of the Big 6, which you can learn all about here, but first, let your regular hosts Jessica Strauss and Peter Newman take you on the crop comp journey in the podcast below!
