- Pub 505 - Leaves become infested with the fungus which causes
stem rust on oats, barley, rye and wheat. The fungus overwinters
on this species and then spreads to the cereal crops causing early
season disease infestations.

Method of Propagation
- New shoots readily grow from cut stumps. Cut and chemically
treat stumps in autumn. Control is labour intensive. Tops are
usually cut off manually and then stumps treated with a basal
bark or stump herbicide treatment. Mowing or spraying of small
plants can be successful to maintain control.
- Similar to Japanese barberry which does not normally host the
rust fungus. Hybids of these two species may host the fungus.
Populations are relatively stable and much lower than for European
buckthorn. Rust does not occur every year but can cause significant
impact in some years.
