Integrated weed management
Seed is the main source of brome grass infestation, and as few seeds remain dormant, the most important aspect of brome grass management is to reduce its seed bank.
Integrated weed management (IWM) techniques are available to manage this weed in crop and pasture (Table 1).
Tactic | Likely control (%) | Control range (%) |
---|---|---|
Burning residues | 70 | 60-80 |
Autumn tickle | 50 | 20-60 |
Delayed sowing | 70 | 30-90 |
Knockdown | 90 | 30-99 |
Pasture spray-topping | 75 | 50-90 |
Silage and hay | 60 | 40-80 |
Grazing | 50 | 20-80 |
Residue collection | 40 | 10-75 |
Harrington seed destructor (HSD)* | 98 | NA |
*98% of the seed collected into the HSD will be killed, so early harvesting will have a better impact than later harvesting due to shedding of weed seed.
