Why Is It Bad?:
The seeds of wild raddish can cause gastroenteritis and kidney disorder in stock. Although the plant is considered to be dangerous there have been few well autheticated cases of poisoning reported in the field.
The lower stem leaves and rosette are a grass green to blue-green colour, stalked 15 to 30 cm long, 5 to 10cm wide. Short stiff bristles makes them rough to touch, upper stem leaves are narrow.
The flowers are white or pale yellow, with violet veins. There are four petals and the flowers are grouped into long, open inflourescences at the ends of stem branches.
Fruit consists of a 2 cell cylindrical pod which are 3 to 8 cm long and 3 to 6mm wide. The seed is reddish or yellow brown, 2 to 4 mm long, covered with a fine surface network.
A slender taproot, 80 to 160 cm long, there are a mass of fibrous laterals in the upper 20 cm of soil.
Single plants or small groups should behand pulled, hoed or spotsprayed before flowering.
Control can be obtained by a programme of successive cropping and controlling the weeds which appear in the crop with herbicides. Please contact your local weeds officer or agronominst for a list of suitable herbicides.

Cultivation & Scalping:
Repeated cultivation is useful but many present erosion problems. It is not completely effective in a cropping situation because of the succession of seedlings emerging within the crop.
