Groundsel Crown Rust (Puccinia lagenophorae) is a fungus in the family Pucciniaceae and is common in Australia and Europe. This cup-shaped rust grows on plants, but does not kill them. Groundsel Crown Rust forms bright orange rust spots and pustules on the leaf surface of host plants. The main host plants are Oxford ragwort (Senecio squalidus) and groundsel (Senecio vulgaris).

Affected plants

  • Groundsel (Senecio vulgaris L.)

Control

Groundsel Crown Rust occurs mainly on cruciferous weeds – not an ornamental or kitchen garden crop, rather a weed. This rust species is also used to control herbaceous species in places where they are a real pest. Restraint is desirable in this regard because Groundsel Crown Rust is not always restricted to cruciferous species and is also capable of crossing with other rust species.

Prevention

Does not apply.
