Barley Grass RIM

A tool to evaluate the profitability of barley grass control methods in the no-till broadacre cropping systems of the Southern Australian grainbelt, on the short, long-term and at paddock scale, in 3 simple steps:

1. Define your paddock

2. Build your strategy

3. Compare your results

Barley Grass RIM came about through the GRDC-funded ‘Maintaining profitable farming systems with retained stubble’ initiative that included an objective of promoting pro-active weed management strategies. Brome grass has become a critical ‘driver’ weed in several grain growing districts under no-till systems and in some areas such as Upper Eyre Peninsula, barley grass is having a big influence on the cropping system.

Using the RIM approach to testing the best Integrated Weed Management (IWM) strategies has been valuable for ryegrass management over a long period, so it was an obvious step to provide agronomists, farmers and researchers with a RIM tool for these other major grass weeds. The new Barley Grass RIM has been developed using the AHRI RIM tool by CSIRO, with support from the University of Adelaide and University of Western Australia, funded by GRDC.
