S06E37 Controlling late season weeds and driving down the weed seedbank

On this edition of the podcast, we’re looking at strategies to control late season ryegrass.


After a good couple of years in much of the Southern Region for rainfall, there is late season weeds coming through the crop.

In this episode, we hear from our Southern Region Agronomist, Greg Condon, who provides a great overview of the tools available to growers.

Elders Agronomist, Jason McClure talks to us about his experience with his clients in Naracoorte and surrounds in South Australia with windrowing to control ryegrass.
