2,4-D update, spray drift advice and how beneficial fungi works to suppress weeds

Would you like to know more about the changes to 2,4-D regulations? Nufarm Technical Marketing Lead André Sabeeney (pictured above) joins us on the podcast to give an overview. He also shares some more broad advice on spray drift. We’re also joined by Professor John Thompson from the Centre for Crop Health based at the University of Southern Queensland. He talks to us about beneficial fungi and its impact on crop growth. Professor John Thompson with Alex Gwynne The benefits for crop growth occur when the beneficial fungus is in combined with the crop root. This is called Vesicular Arbuscular Mycorrhiza. It previously was referred to as VAM and now more commonly AMF. A lack of AMF can result in poor early crop growth and therefore poor crop competition with weeds. We also learn more about a similar effect of root-lesion nematodes causing poor growth of intolerant wheat varieties and poor weed suppression.

Farmers share their harvest weed seed control experiences with Planfarm Agronomist Dani Whyte

We have a special guest co-host this week, with Planfarm Agronomist Dani Whyte joining Jessica Strauss, providing insights on farmer interviews she conducted last harvest. Dani has been working on a GRDC RCSN project, looking at harvest weed seed control practices in the Kwinana East port zone. She conducted 10 farmer interviews in total. In this podcast, we hear from three of the farmers who participated in the project. Farmer Ty Kirby runs chaff decks on his property. Farmers Clint Della Bosca (pictured at the top), Stephen Dolton and Ty Kirby all share their HWSC experiences. Planfarm Agronomist Dani Whyte in the field. The focus of this project is getting the weeds in the front of the header in low yielding crops.  The core messages are: Harvest low – 10-15cm (this means paddocks need to be clean of rocks/stumps and staff need to be trained accordingly) Coreflute attached to finger tyne reel Knife extensions/crop lifters on the front of the harvester Farmer Stephen Dolton

Crop topping, using Sharpen & getting ready for harvest

In the podcast this week, we focus on crop topping and the relatively new herbicide, Sharpen. In our last podcast, Andrew Messina talked to us about Case IH harvester set-up. This week farmer Lance Turner gives us the rundown on John Deere gear. AHRI and WeedSmart Agronomist Greg Condon talks to us about the benefits of crop topping and what to do if you suspect you’ve got herbicide resistance. We also hear from BASF Technical Services Manager, Phil Hoult, about the herbicide Sharpen. It’s now registered as a harvest aid in winter pulses, for winter cleaning of Lucerne and for wild radish seed-set control in winter cereals, so we’ll find out in more detail about its applications for broadacre croppers.

Harvester set-up and implications of hay crossing borders

In the podcast this week, we’re focusing on harvester set-up and we also discuss how to capture weed seeds in the chaff fraction. John Broster from Charles Sturt University gives us some insight into the research he and Michael Walsh (University of Sydney) did on capturing weed seeds. A few years back, they measured how many weed seeds were entering the chaff fraction in a modern harvester. We learn what this means for growers. We also hear from WA farmer Andrew Messina about setting up Case harvesters. Finally, with the terrible drought conditions in Queensland and NSW, many farmers have had to source feed from totally different parts of the country. We chat with Grains Farm Biosecurity Officer for Biosecurity Queensland Kym McIntyre about the implications. A candid shot of WA farmer Andrew Messina. Andrew has been practising HWSC for more than two decades We also talked about a great opportunity being offered by the GRDC in the podcast. Did you know your group can apply for the GRDC “Grower Development Awards – Study Tours” to potentially help fund your trip to WeedSmart Week next year? Applications close Oct 9.

Australasian Weeds Conference overview

In this podcast, we’re focusing on research and ideas out of the 21st Australasian Weeds Conference, which this year was held in Manly (hence the beach picture above!). WeedSmart’s Jessica Strauss was lucky enough to attend and caught up with a number of researchers who presented. The AWC is a biennial conference and carries on a long tradition of bringing the weed management community together to discuss new developments and share information about cutting-edge and best weed management practices. The WeedSmart booth at the Australasian Weeds Conference The conference attracts more than 250 delegates from across Australasia and globally. In this podcast, we hear from Professor Antonio DiTommaso from Cornell University. He was the International Keynote Speaker and spoke on the topic “Climate Change and Weed Migration: What do we know and what next?” Professor Tony DiTommaso Dr Michael Widderick, who is the Principal Research Scientist at the Queensland Department of Agriculture and Fisheries also presented. He spoke on “Research priorities for weed suppression by crops in Australia”. Dr Michael Widderick Last, but not least, we hear from Dr Cheryl McCarthy. She’s a Research Fellow at the Centre for Agricultural Engineering at the University of Southern Queensland. She spoke on “Machine Vision Systems for Robotic Weed Sensing in Real World Commercial Environments”. Dr Cheryl McCarthy

Cross-resistance update from Chris Preston and Truflex Canola explainer

Serious herbicide resistance news has come out of South Australia, with a population of ryegrass from the Eyre Peninsula, having been confirmed resistant to all of the pre-emergent herbicides – Avadex, Arcade, Trifluralin (shown in the above image), Propyzamide and Sakura, as well as two lesser-known herbicides EPTC and Thiobencarb. It was sampled in 2014 just two years after the release of Sakura in Australia. Metabolic cross-resistance is at play here. The really serious news is that a random survey in the South East of South Australia found many more populations of ryegrass with multiple cross-resistance to a range of pre-emergent herbicides, and the perplexing thing is that there is no predictable cross-resistance pattern. This is the research by the team of Chris Preston, Peter Boutsalis, David Brunton and Gurgeet Gill from the University of Adelaide with GRDC investment and we speak with Chris Preston about the findings and what they mean. If you’d like to learn more about the technical side of this finding, you can read AHRI insight here. In positive news, we learn about Truflex® canola with Roundup Ready® Technology which is planned to be released by Monsanto in 2019. TruFlex canola is Monsanto’s second-generation weed control trait offering growers greater flexibility through an extended glyphosate application window up to first flower and an opportunity to apply Roundup Ready® Herbicide with PLANTSHIELD® by Monsanto at higher rates for enhanced weed control. Truflex canola trial sites in Cunderdin, WA AHRI Director Hugh Beckie explains how the technology works and WA Grower Chad Eva gives his perspective on how it will fit into his farming system. If you’d like to learn more about this technology in person, you can head along to a field day near you. Find out more here. Finally, we catch up with WeedSmart Content Writer and Producer Cindy Benjamin, to learn about who she is and get an update on what’s new on the WeedSmart website.

WeedSmart Week is coming to the Northern Region!

As a whole, the northern grains region has had a very tough start to the 2018 winter cropping season. With a few showers around there are hopes of some reprieve from a long, dry spell. Unfortunately, weeds will most likely be the first to respond to rainfall and growers will need to make some difficult decisions surrounding their cropping program, pre-emergent herbicide applications and maximising the competitiveness of any crops that get established. In this podcast, we hear from grower Brad Jackson and agronomist Peter McKenzie about why attending WeedSmart Week is a valuable investment of your time. WeedSmart Week, aimed specifically at growers and agronomists, will kick off in Narrabri with the Forum Day on 20 August, followed by two days of farm visits in the region. Three growers from the region who attended the 2017 WeedSmart Week in Wagga Wagga will be making presentations over the three days, outlining ways they have tackled herbicide resistance head-on. Grower, Brad Jackson, will present at WeedSmart Week. One of those growers is Brad Jackson, who farms with his father Peter and brothers Phil and Matt at Gurley where they usually have a robust winter cropping program featuring wheat, barley, chickpea, canola and linseed. Following 2017 WeedSmart Week they’ve reintroduced the use of pre-emergent herbicides to their herbicide program and are taking every opportunity to mix and rotate herbicide modes of action. The Jackson’s WeedIT optical sprayer has revolutionised their herbicide program, allowing them to spray low weed density paddocks more frequently and target small, fresh seedlings. Brad and Phil are also developing valuable weed management tactics, such as camera-guided inter-row cultivator and green manuring, that can be employed in an organic farming system at Westmar. WeedSmart Week attendees will have several opportunities to see and discuss cutting-edge technologies such as optical sprayers, autonomous tractors and emerging ‘green-on-green’ spray sensors. The growers, agronomists and researchers who will speak and participate in expert panels at the Day 1 forum will spark important discussions about herbicide resistance and how the Big 6 tactics can be used to target the weed species and farming systems in the northern cropping region. There’s one thing for sure – doing nothing is not an option. Register for this important 3-day event for the single ticket price of $95 here.
