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.


  • Globodera rostochiensis, golden or potato cyst nematode (PCN) and G.

  • Potato cyst nematode (Globodera rostochiensis, PCN) was detected on six properties in the Perth Metropolitan area between 1986 and 1989.

  • Severe skin itching in humans can be caused by bites from species of straw itch mite.

  • DDLS Seed Testing and Certification is responsible for administering the industry seed potato production schemes in Western Australia.

  • Pale green, cigar-shaped, caterpillar up to 12 millimetres in length.

    The diamondback moth (DBM) caterpillar is a serious pest of brassicas that is difficult to control.

  • Affected plants are stunted with few tillers.

    A soil-borne pest affecting roots of cereal crops, cereal cyst nematode (CCN) can cause substantial yield losses, particularly in continuous cereal crops.

  • Cabbage white butterfly caterpillar

    Larvae of cabbage white butterfly are often found in canola crops. The larvae consume leaves but numbers are very rarely high enough to cause serious damage to the crop.

  • Brown pasture looper caterpillar

    Caterpillars with a characteristic looping motion that chew seedling broadleaf crops.

  • Cabbage aphid

    Small soft-bodied winged (adults only) or wingless insects that damage canola by direct feeding or as a viral disease carrier.

  • Cutworm moths

    Cutworm caterpillars feed on seedling leaves and stems near ground level with stems often chewed through and ‘cut’ to ground level.
