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.

    An aphid borne viral disease in canola that has the potential to cause significant yield loss with early infection, but rarely occurs in WA.

  • Group I herbicide damage can also cause root nodules

    Clubroot is caused by a soil-borne fungus that only affects plants in the Cruciferae family including canola,mustard, wild radish, wild mustard, wild turnip and vegetable brassicas.

  • Rhizoctonia affected seedlings develop red-brown hypocotyl lesions as shown by the middle seedling

    Damping-off is seedling root and hypocotyl (seedling stem) disease that can be caused by a complex of Rhizoctonia, Fusarium and Pythium fungi.

  • Yellow areas on upper leaf surface

    A fungal disease infecting foliage of canola, it mainly affects seedlings and is rarely found beyond the rosette stage.

  • This report outlines the work undertaken by the Grains, Seeds and Hay Industry Funding Scheme for bedstraw eradication during the 2013/14 financial year.

  • Leaf necrosis moves from leaf edges to veins

    A range of group C herbicides are registered for use in triazine tolerant (TT) varieties, but other varieties are susceptible to both pre and post emergent applications.

     

  • Emerging leaves are distorted and discoloured; leaf blades become cupped and crinkly

    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.

  • 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
