The Weed Seed Wizard is a national collaborative project which uses paddock management information to predict weed emergence and crop losses now and in the future.


The Weed Seed Wizard is a computer simulation tool which:

  • applies to all Australian grain growing areas
  • helps growers understand and manage weed seedbanks on their farms
  • uses farm management records to simulate how different crop rotations, weed control techniques, irrigation, grazing and harvest management tactics can affect weed numbers, the weed seedbank and yields
  • uses farm-specific management and site-specific weather
  • is multi-species;
    • annual ryegrass, wild radish, wild oats, barley grass, rigid brome grass, rip-gut brome grass, fleabane and silvergrass in the southern regions
    • barnyard grass, liverseed grass, sweet summer grass, feathertop Rhodes grass, bladder ketmia, sowthistle, fleabane, cowvine and bellvine in the north.

It is a collaboration between:

  • Department of Primary Industries and Regional Development
  • Grains Research and Development Corporation
  • University of Western Australia
  • University of Adelaide
  • NSW Department of Primary Industries
  • Queensland Department of Agriculture, Fisheries and Forestry.
