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.

    Glyphosate is a systemic knockdown herbicide that is used extensively for brown fallow, summer weed or pre-seeding weed control, or selective weed control in glyphosate resistant crops.

  • Scattered germination due to insufficient soil moisture

    Early drought may affect germination and early growth. Water stressed seedlings are more severely affected by other constraints and may have induced nutrient deficiencies.

  • Flattened strap-like flowering stem

    Fasciation is a relatively rare condition of abnormal growth in the growing point that has no economic significance in canola.

  • Uniformly affected plants with pale leaf blotches

    Group F herbicides are registered for selective control of wild radish, wild mustard and wild turnip in cereals, legume crops and legume pastures. Canola is less affected than brassica weeds

  • Citrus ‘whiteflies’ or ‘snow flies’ (Aleyrodidae) resemble small, white moths, but actually belong to a group (Hemiptera) closely related to lerp insects, aphids and scales.

  • Summer crops can be grown for various reasons including replacing a ‘missed’ cereal crop, control herbicide resistant weeds, filling a summer feed gap for livestock or for watertable control.
