Management of brome grass

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).

Table 1 The efficiency of various control strategies available for suppressing brome grass
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.
