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.

  • In 2022, the department is conducting more than 300 research trials across the state from Kununurra in the north to Esperance in the south.

  • 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 interference at seeding time.

  • The term 'residual' applies to a number of herbicides that have a long lasting activity in the soil. These herbicides are often applied directly to the soil prior to planting crops, pre-emergent.

  • Spray-topping is a very effective method for managing annual grass seed set in pastures.

  • 'Crop-topping' is the late application of herbicides to prevent weed seed-set.

  • Spray-topping or pasture topping is the application of a sub-lethal rate of herbicide when grasses are coming into head and flowering.

  • In Western Australia's Mediterranean-type climate, the survival of pests and diseases over summer is often critical in determining pest outbreaks and disease epidemics in broadacre crops.

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

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

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