Class 2 - The plant must be eradicated from the land and the land must be kept free of the plant.
Class 4 - The growth of the plant must be managed in a manner that reduces its numbers spread and incidence and continuously inhibits its reproduction and the plant must not be sold propagated or knowingly distributed
Why Is It Bad?:
Cape broom is weedy especially in temperate areas such as the tablelands. It has a long-lived soil seed bank which will germinate significantly after disturbance. It is often a weed of natural environments and wastelands but can also affect agricultural lands. It can form dense infestations if not controlled before seed set. Ripe seed pods pop open in hot weather, dispersing seeds several metres.
Leaf consists of 3 leaflets which are slightly hairy on both sides, but more so the underside.
Flowers are yellow, pea-like, 8-12mm long.
Seed pods are light green, maturing to brown/black, hairy and pea-like. Each pod contains 3-8 seeds. Seeds are brown/black, smooth, rounded, 3mm long.
A crown grows below the soil surface, regrowth will occur from here easily.
Entire plants need to be removed, including the crown from below the soil surface. Failure to remove the crown will result in significant regrowth. Any material removed needs to be disposed of responsibly. Integrated weed management is recommended for successful control.
Herbicides are often used for foliar spray or cut-stump methods. Please refer to the Noxious & Environmental Weed Control Handbook or your friendly local weeds officer for more information. Integrated weed management is recommended for successful control.
Can be used to stimulate germinations to exhaust soil seed bank but must be followed up to ensure seedling growth is destroyed before flowering. Fire is NOT recommended as a primary control technique for established plants. They will burn dangerously hot and often this will not kill established plants. Regrowth will occur from the crown which is protected in the soil. Integrated weed management is recommended for successful control.
Slashing & Cutting:
Goats will eat adult plants while sheep prefer to graze seedlings. Integrated weed management is recommended for successful control.
Cultivation & Scalping:
Integrated weed management is recommended for successful control. Establishing a competitive pasture can be used to help prevent mass germinations from establishing.
Successful treatment programs rely on ongoing monitoring of sites. Regrowth and new seedlings can easily become larger infestations if follow-up treatments are not part of the management program.
