The Department of Agriculture and Food, Western Australia (DAFWA) has significant direct investment in grains research, development and extension capability and activities, research infrastructure and policy development.

The Western Australian grains industry is a major contributor to the agrifood sector and the Australian economy.  WA produces on average 13 million tonnes of grains (cereals, oilseeds and pulses) each year.  Grain exports generate more than $4 billion (five year average) for the WA economy each year – making it the largest agricultural sector in the state, and the fourth largest export industry overall after iron ore, oil and gas, and gold.

WA exports about 80% of its annual grain production to more than 50 countries worldwide. Indonesia is WA’s top wheat export market worth over $0.5 billion per year. WA is the world’s leading supplier of premium malting barley to China, the major supplier of wheat for the Japanese udon noodle market, and a major feed barley supplier to the Middle East.

In the 2014/15 season it is estimated the WA grains industry exported a total of $3.7 billion of cereals and $790 billion of pulse, pasture and oilseeds. The major contributors to these exports were wheat ($2.7 billion), barley ($905 million), canola ($710 million), oats ($83 million) and lupins ($77 million).


  • Symptoms appear first and most severely on the oldest leaves. Progressive death starts from the leaf tips and margins.

    Boron toxicity is usually an inherent feature of a soil and is a particular problem when high boron levels occur in the subsoil.

  • Brown-black discolouration of glumes ranging from slight lines through to large areas covering most of the glume.

    A physiological condition associated with the presence of a rust resistance gene in some wheat varieties. Yield impact unknown.


  • Light flecking on younger leaves that become more severe on older leaves

    A physiological condition associated with the presence of rust resistance genes in some wheat varieties that causes leaf damage. Yield impact is unknown.

    If you are deep-ripping, ploughing or spading to remove subsurface compaction or another constraint, it is a good idea to incorporate lime in the same operation.

  • 16 November 2016

    The rate of soil acidification due to agriculture can be reduced but not eliminated. Liming will always be needed to prevent the soil from becoming too acidic.

  • 16 November 2016

    Liming to recover an acidic soil to an appropriate pH can result in significant production benefits, however a response to liming indicates that previous production has been lost due to an acidic t

  • All exposed parts are affected, more on one side with spray drift
    26 June 2015

    This category includes contact herbicides from a range of chemical groups that require uniform spray coverage to be fully effective.

  • Barley plant death from Fusilade® spray drift from neighbouring lupin paddock
    29 May 2015

    These are post-emergent grass contol herbicides used for annual ryegrass and/or wild oat control in wheat and barley or non-selective grass control in broadleaf crops.

  • Leaf symptoms occur when the seedling emerges but roots remain normal
    4 February 2015

    This category contains root pre-emergent Group C herbicides.  Post-emergent use in cereals are simazine (silver grass control), and diuron+MCPA (broadleaf weed control).

  • Dying wheat seedlings with short thick coleoptiles and spade-tip roots
    29 May 2015

    These are pre-emergent herbicides for the control of grasses and some broadleaf weeds in specific cereal crops.
