‼️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.

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.

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.
