Articles and events

Our content writer Cindy Benjamin has written some excellent articles this month.

1. Make every drop of herbicide count: For ten years, WeedSmart has stood alongside growers and agronomists, promoting science-backed practices known to drive down the weed seed bank and stave off the threat of herbicide resistance. To mark this milestone, the WeedSmart team and our research partners have reviewed the WeedSmart Big 6 tactics and made a few modifications, including the addition of ‘Optimise spray efficacy’.

2. Plan your attack on the weed seed bank: Controlling weeds is an on-going task and requires determination and persistence. Having a great plan of attack is essential. Here we summarise the key components of the WeedSmart Big 6 strategies and the principles that underpin them. You can also test your plan using AHRI’s Weed Integrated Management (WIM) decision support software for annual ryegrass, brome grass, barley grass, wild oats and barnyard grass. Read more here.

3. How can I best tackle sterile oat in Northern region wheat crops? In this Ask an Expert, we chat with with Gulshan Mahajan, Adjunct Associate Professor, Queensland Alliance for Agriculture and Food Innovation. Sterile oat (Avena ludoviciana) is the northern region’s most competitive grass weed in cereal crops, costing growers more than 20 thousand tonnes in yield loss and a revenue loss of $4.5 million. Dr Mahajan, says an integrated approach to controlling this weed will save yield and drive down the weed seed bank. Read more here.

4. Upcoming Webinar

Webinar: Combating resistant annual ryegrass in northern farming systems

In this webinar, Nutrien agronomist Garry Onus will talk about practical strategies to prevent and manage incursions of resistant annual ryegrass populations in northern cropping systems.

Brad Jackson and his family run a 1,700 ha cropping operation in Gurley, in northern NSW, in addition to a 400 ha organic farming system at Westmar, southern Queensland. Brad will share the cultural, mechanical and chemical strategies he deploys to keep annual ryegrass at bay.

This webinar will be happening on August 9th and will be facilitated by our Northern Extension agronomist Paul McIntosh. Make sure you
