Importance Wild radish is a major weed of winter grain crops, and to a lesser extent pastures, in southern Australia. It is less common in pastures and undisturbed areas because of competition from other species, grazing by stock and the absence of soil disturbance.
Wild radish competes vigorously with crops.
Densities of 10 wild radish plants per square metre can reduce yields in wheat by up to 20 per cent. The fibrous stems of wild radish choke header combs, making harvest difficult. Most delivery points will have quite strict dockage limits. The green stems are high in moisture, which may raise the moisture content of grain above levels acceptable for storage. The green pod segments have a toxic effect on stored grains, resulting in reduced grain quality.
