Rapistrum rugosum

Other common names:

Giant mustard.

Description:

It is a common weed seen in farming, roadsides and other agricultural areas. The persistent weed develops a dense canopy eliminating native and desirable plants and grasses. The weed can grow to up to 60 cm tall. Its distinct yellow petals are accompanied by sepals that stand vertically at near right angles. Distinct fruit, pods, can also be seen on the flowering stem. Turnip weed can produce up to 77,000 seeds per plant (Wilson et al., 1981).

Susceptible Turf:

Warm-and cool-season turf grass varieties.
