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.
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.
