Join WeedSmart Southern Extension Agronomists Jana Freebairn and Chris Davey in discussing the rising resistance to imi’s (imidazolinone) in broadleaf weeds, in 2024 and beyond.
Imi resistance is a growing issue within our cropping systems and is becoming ever more important when considering crop rotation, herbicide selection and yearly environmental pressures.
Jana and Chris share their experiences with imi resistance so far this year in the Southern Region of SA and the Eyre Peninsula, speaking to what they have seen within lentil crops and how the WeedSmart Big 6 can assist.
Delivered by our WeedSmart Extension Agronomists, Header Run videos are created for the on-the-move grower and are suitable for a watch or listen. The video can be found on our website.Learn more about WeedSmart by visiting our website. Don't forget you can follow us on Twitter too.

Ian Pursehouse is our guest for this episode of the Regional Update.
Located in NSW, in West Wyalong, Ian and his family transitioned from a mixed operation to 100% dryland cropping in the late 2010's, and have been learning from every experience since.
Ian has a systems-focused approach, with an emphasis on optimising rotations to not only control weeds - one of the WeedSmart Big 6 principles - but minimise costs across the board. After a less-than-ideal season with low rainfall and frost, his philosophy of "controlling what you can" and strategic investment have ensured they are prepared for whatever comes next.

The WeedSmart Big 6: Rotate Crops and Pastures Weeds love predictable rotations. They find it easy to evolve resistance to herbicides when they are used in a predictable manner. If we mix it up a bit, the weeds get confused and find it harder to adapt to the farming system.

This Regional Update Podcast episode, we're joined by grower Stuart Vlahov from Western Australia.
Stu is a grower in Ellendale, WA, around 35kms south-east of Geraldton near Walkaway, who has recently been using two drones to spray crops within his mixed farming operation spanning 3500ha.
With bogged crops and wild radish flourishing, Stu is employing the two DJI drones for weed control and fertiliser application. Talking with us about the drone's short down time, price, set-up and future applications, Stu is keen to see the space change and evolve.

1. Testing optical sprayer technology return on investment: Machinery prices have sky-rocketed in recent years, leaving many growers wondering whether new technologies, like optical spot sprayers, can pay their way. Peter Newman, Planfarm farm business consultant and WeedSmart western extension agronomist, has run some figures for his clients to help them with boomspray purchase decisions, and found that the benefits often outweigh the upfront cost of weed detection technology.
2. Measuring the value of weed control expenses: Weed control is expensive, and it is often hard to measure the return on your investment.

1. Investment in holistic weed management pays off: An independent evaluation noted that WeedSmart has found a ‘real sweet spot to take a holistic approach to problems and develop viable solutions without bias’. Growers commented that WeedSmart has helped them be more aware of potential risks with farm management, crop rotations and chemical use, and keeping weed management front of mind when making all decisions.
2. By-pass mode can extend impact mill life: High rainfall region growers Stewart and Jessica Wallace (Esperance, WA) swapped their chaff carts for a weed seed impact mill to avoid burning the chaff heaps and retain all the crop residues on the paddock while driving down the weed seed bank.

We don’t often take the time to calculate what yield reduction weeds are actually responsible for, or what a well-planned rotation for weed management can make a farming business.

Articles
1. Windrowing barley plus HWSC in the high rainfall zone: Tim Williams (Conmurra, SA) uses the barley phase to really drive down their weed seed bank. Tim says they windrow the barley as early as possible, cutting it low to the ground. This minimises weed seed shedding, particularly in ryegrass, so they can capture the seed and process it through the impact mills at harvest.
2. Never miss an opportunity to tackle weeds: Lance Turner says herbicide resistance, particularly glyphosate resistance, was going to take them out of cropping if they didn’t start using harvest weed seed control. Twenty-five years on and the Turners still have the newer chemistries ‘up their sleeve’.
3. Mills impact the weed seed bank: Bruce McLean farms at Bool Lagoon in South Australia’s high rainfall zone. He says that the limited harvest hours in the region were a major deterrent when it came to implementing harvest weed seed control, but they have found that the impact mill doesn’t slow them down too much, and they have the option to bypass it if necessary.

Our content writer Cindy Benjamin has written some excellent articles this month.
1. Keep clear of paraquat-resistant fleabane: The lack of new broad-spectrum knockdown herbicide options means that growers need to be working hard on other management tools where the double-knock is losing efficacy. Agronomist Barry Haskins gives his top tips to control fleabane.
2. Tackle weeds and herbicide resistance with the Big 6: Nutrien agronomists from across the country shared their tips to help control crop weeds.
3. Can annual ryegrass be beaten in the Northern region? Annual ryegrass is a relatively new weed in the North. With its capacity to produce large amounts of seed and readily evolve herbicide resistance, growers and agronomists should avoid widespread infestation. Garry Onus, senior agronomist with Nutrien Ag Solutions, in Moree, NSW, gives his top tips to control annual ryegrass in northern farming systems in-crop and in the fallow.
4. Does ambient temperature affect herbicide performance? Applying herbicides outside the optimal temperature range is likely to contribute to a spray failure, even in susceptible populations. For example, twice as much clethodim is required to kill ryegrass if the product is applied after 3 days of frost. And glyphosate efficacy is much better at 20°C than at 30°C. Associate Professor Chris Preston (The University of Adelaide) explains how ambient temperature affects herbicide performance.
