Weed Seed Wizard

As weed seed management gains traction as a key strategy for managing herbicide resistance, northern region grain advisers have a new tool for assessing the extent of the challenge.

The Weed Seed Wizard was developed in WA and is being brought to Queensland and NSW with support from the Grains Research and Development Corporation (GRDC).

Workshops to help advisers get to know the computer simulation tool and design weed management strategies for clients that can improve yields are being held at three locations, including:

Mr Congreve says Weed Seed Wizard can be fine-tuned to individual farms using local weather data, soil type and management options.

It can also be used to manage a range of weed species, such as barnyard grass, sweet summer grass, wild oats and annual ryegrass, depending on locality, he says.

“The Weed Seed Wizard can help advisers understand and predict the impact of weed management decisions on crop yield and weed seedbanks.”

While there is no cost to participate, numbers are strictly limited and it is advisable to book early to secure a spot.

Participants are required to bring a laptop (Macs and mobile devices won’t run the software as yet).
