PODCAST: Getting mixing right to avoid glugs & efficacy issues

Our latest podcast focuses on getting tank mixes right to avoid glugs and ensure they’re as effective as they can be.

Bayer Market Development Agronomy and Field Leader of Integrated Weed Management Australia, Craig White, talks to us about how to get mixing orders right to avoid glugs in tanks and to get the best tank-mix possible. We also hear about a new formulation of Sakura called Sakura Flow. Nufarm Territory Manager for the Downs, Maranoa and South West Queensland, Malcolm Salisbury joins us on the podcast to provide an overview of some of the considerations that need to be made when mixing herbicides for the Northern Region. He also has some general tips on mixing too!

Next WeedSmart Week to be in South Australia!

WeedSmart Week is designed to engage growers and advisors on WeedSmart's Big 6 messages. Our objective for this event is for you to learn everything you need to know about weed management. You hear first-hand from growers and agronomists about integrated weed management practices to minimise the impact of herbicide resistance.

Our next WeedSmart Week, whether that is this year or in 2021, will be held in Clare, South Australia. As the COVID-19 situation develops, it is hard to predict how we will be able to move forward. Our current date for WeedSmart Week this year is Tuesday, August 4th until Thursday, August 6th. We will keep you informed as to how we will proceed.

For now, we’ve created a sign-up list for growers and industry to register their interest and be the first to know more details about the program and release of tickets. If you’d like to be potentially involved as a presenter on our forum day or would be open to having the group visit to see first-hand how you are tackling weeds on your farm, we’d love for you to get in touch with us directly by emailing us at

Webinar: Know thy enemy - biology of our most problematic crop weeds with Dr Catherine Borger

Brome grass and barley grass are ranked as the fourth and ninth most detrimental weeds nationally. These weeds cost growers $22.5 and $1.7 million per year, respectively. Understanding the ecology of these species is vital to developing a successful weed management plan.

A five-year GRDC project produced results on emergence patterns, seed bank persistence, seed shedding, and competitive ability of great brome and barley grass, in Western Australia and South Australia (‘Seed bank ecology of emerging weeds’ UA00156). The project found that three to four years seed set control was needed to remove a great brome or barley grass soil seed bank.

Chaff lining has really taken off

Chaff lining has been a dominant talking point in farming communities as an easy to adopt, low-cost HWSC tool. It has also experienced relatively rapid adoption across the country. Check out our latest video to learn more.

Podcast: Weather forecast accuracy and crop competition trial results
