Post-emergent herbicide tolerance of small-leaved bluebush (Maireana brevifolia) locations
Aims

To find herbicide options that may be safe to use in saltland pasture systems wherein a farmer can maintain the productive capacity of his saltland by controlling his weeds. Trials also aim to explore weed control options during saltbush germination.

Key messages

Standard farmer practice of 'pasture topping' in the previous year, followed by a knock down around the seasons break, remain the best practice before sowing saltbush or bluebush by seed.
