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,
'Crop-topping' is the late application of herbicides to prevent weed seed-set.
Sclerotinia stem rot caused by Sclerotinia sclerotiorum is becoming more widespread in recent years in canola across the wheatbelt.
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.
Group F herbicides are registered for selective control of wild radish, wild mustard and wild turnip in cereals, legume crops and legume pastures.
This category contains root pre-emergent Group C herbicides such as simazine and metribuzin that are routinely used in lupins. Post-emergent atrazine damages lupins.
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 highly toxic to lupins.
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.
