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).

  • First sign is new growth yellowing

    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.

  • The pattern of damage reflects spray coverage

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

     

  • Blotches can vary from white / yellow to mauve / red

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

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

    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).

  • Normally plants wilt, twist, become discoloured and then die

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

  • Burst coleoptile in metalochlor damaged wheat

    This pre-emergent herbicide group is used to control annual grasses and broadleaf weeds. It is applied to the soil either before or directly after sowing and prior to weed emergence.

  • 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
