‼️2025 season finishing for Quick-Test ‼️
As weeds enter the reproductive stage, they don’t recover well after being collected, and so they can’t be sprayed. Wait a few weeks, then collect seeds and send them in for testing over summer and autumn.
Testing for herbicide susceptibility and resistance - WeedSmart
There are several reasons why weeds might survive a herbicide treatment but it is increasingly common for herbicide resistance to be the culprit.

SLR research agronomist Louise Fraser led trials on farms at Dalwallinu, Goomalling and Kellerberrin, WA, comparing a wide range of commonly-used pre-em herbicides applied IBS or IBS fb EPE. 💦 🌱 Check out the results!

SLR’s CEO Michael Lamond says growers visiting the pre-em trials can weigh up the options that best suit their individual paddocks, giving thought to weed density and herbicide resistance profile, potential yield and future crops in the rotation. 💦 🌱 buff.ly/GGjbiWr

A bit confused about all the precision ag tech for weed control? 🤯
WeedSmart’s Chris Davey sees the Big 6 as a valuable planning tool for assessing which precision ag technologies or practices have a good fit in your system.
Navigating precision agriculture for weed control - WeedSmart
There are technologies and systems that have the potential to achieve gains in each of the six pillars of the WeedSmart Big 6.

New technologies in automated weed detection and spot-spraying are bringing many benefits for weed control, herbicide stewardship and maintaining a willing workforce within reach for more cropping enterprises.

Weed control will always be a numbers game. When considering any new technology, the big question is whether it will help you achieve 96 per cent weed control or better. There are effective practices to adopt in each of the WeedSmart Big 6 pillars.

Steven Tilbrook, agronomist with the CBH Group in Western Australia, says that two of the greatest risks to Australian grain markets are weed seed contamination and chemical residues. It’s about choosing the best options and getting the timing right.

Three high-priority MRL risks to manage: 1. Haloxyfop in canola, 2. Paraquat in lupins and 3. Glyphosate in canola. In addition to the Directions for Use tables, labels now have very specific Residue Management Restraints that must be followed. buff.ly/C1QWVaS

In-season herbicides accounts for 55% of the total weed control spend for grain production, or $97/ha. Another $51/ha in other in-crop weed management practices and $29/ha to control weeds on fallow fields. buff.ly/QZU3Tvs

New national report by CSIRO indicates growers are ‘seedbank aware’ – implementing long-term, economically optimal strategies to keep in-crop weed numbers low. Data analyst Jackie Ouzman says the av. annual spend on weed control on grain farms is $176/ha.
Keeping weed numbers low pays off - WeedSmart
CSIRO’s Jackie Ouzman, says growers’ investment in weed control is minimising yield losses from residual weeds growing in crops and fallows.

How much wheat yield does ryegrass steal? As a rule of thumb – 0.45 t/ha wheat grain yield is lost for every 235 ryegrass spikes/m2. Check out our scientific summary and read CSIRO’s research paper. 🧐 buff.ly/sMzaYkh
Science backs the double break against ryegrass 🏆 Identifying profitable crop sequences that also reduce the weed seed bank is a big win-win for growers!
CSIRO experiments in southern NSW found some winning combinations.
Science backs Double-breaks to beat Annual ryegrass - WeedSmart
A double-break is a strategic tactic to deploy within the WeedSmart Big 6 to drive down the weed seedbank throughout the crop sequence.

Need to break an annual ryegrass stranglehold??
Try 3 years of over 95% weed seed control followed by high-level control in subsequent years. Think consecutive broadleaf crops (e.g. legume plus canola) or a broadleaf crop followed by cereal hay.

Farming with low weed numbers makes it easier to produce low or nil residue grain that can be sold into the most profitable market – it’s another way the WeedSmart Big 6 framework helps make sure that weeds are not calling the shots in your business. buff.ly/C1QWVaS
