Crops

The Department of Primary Industries and Regional Development continues to support the growth and international competitiveness of all crop industries in Western Australia.

With a 2400 kilometre span from its tropical north to its temperate south, WA supports a broad range of cropping industries from rain-fed winter cereals through to irrigated horticultural crops.

In the 2012/13 year the WA cropping industries exported a total of $3.9 billion which comprised: $3.1 billion of cereals, $859 million of pulses, pastures and oilseeds, $142 million of horticultural crops. The major contributors to these exports were wheat ($2.7 billion), canola ($756 million), barley ($377 million), lupins ($42 million), carrots at $48 million, oats ($12 million), and strawberries at $5.5 million.

  • Brome grasses (Bromus spp.) are highly competitive weeds, most problematic in wheat crops.

  • Annual ryegrass (Lolium rigidum) is one of the most serious and costly weeds of annual winter cropping systems in southern Australia.

  • Windmill grass (Chloris truncata) is a native species and is the tenth most common summer weed species in the Western Australian wheatbelt.

  • ‘Risk-aware’ growers can implement strategies to reduce and avoid unnecessary introduction and spread of weeds.

  • Herbicides play a vital role in integrated weed management programs.

  • One-off soil inversion results in the complete burial of the water repellent topsoil in a layer typically at a depth of 15–35cm, and brings to the surface a layer of wettable subsoil.

  • In poor growing seasons, crops may not be good enough to harvest.  Managers need to make some tough decisions, after assessing feed value for livestock, potential weed seed set, level of herbicide

  • In 2020 the Department is conducting over 300 Grains Research trials across the state from Kununurra in the north to Esperance in the south.

  • The Chemical weed control in canola bulletin has been produced by the Department of Primary Industries and Regional Development, with co-investment from the Grains Research and Development Corporat

  • Summer weeds can rob subsequent crops of soil nitrogen and stored soil water. They can also reduce crop emergence by causing physical and/or chemical interfence at seeding time.
