Control methods

Pests, weeds and diseases (pests) pose serious risk for primary producers as they can impact on market access and agricultural production. Pest control is best achieved with an Integrated Pest Management plan using a range of biological, chemical, mechanical, physical or cultural control methods.

To reduce the impacts of pests, the Department of Primary Industries and Regional Development:

  • works with landholders and grower/community/biosecurity groups on control
  • provides diagnostic services and information on prevention, management and treatment
  • provides biosecurity measures to prevent introduction, and to eradicate or manage current pests.

For advice on control methods search our website or contact our Pest and Disease Information Service (PaDIS).

  • Information is provided here to assist management of diseases and viruses that occur in broadacre crops grown in Western Australia - cereals (wheat, barley, oats and triticale), pulses (field pea,

  • Young growth twists rapidly after herbicide application

    Group I herbicides are used for broadleaf summer weed control or selective broadleaf weed control in cereals. Damage can be caused by soil residues, spray contact or vapour drift.

  • White chlorosis on tendrils and spray contact points

    Group F herbicides are registered for selective control of wild radish, wild mustard and wild turnip in cereals, legume crops and legume pastures.

  • Reduced and delayed emergence

    These are pre-emergent herbicides for the control of grasses and some broadleaf weeds in crops. Group D herbicide damage in field peas is rare.

  • Metribuzin damage. Typically scorched ends/edges of older leaves and tendrils

    This category contains root pre-emergent Group C herbicides such as simazine and metribuzin that are routinely used in lupins, but damage field peas.

  • Affected plants are stunted with reduced root systems

    Sulfonlyureas, imidazolamines and sulfonamides are systemic herbicides that are used for pre and/or post emergent grass and/or broadleaf weed control in cereals and are mostly highly toxic to peas.

  • The first sign is yellowing/ reddening and sometimes interveinal chlorosis of new growth

    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.
