Identification

Rust fungi are characterised by their orange-brown pustules which are irregular in shape and size.

Growth factors

The disease is particularly bad when the weather is damp and wet.

Symptoms

Faint, yellow, dusty markings on the upper sides of leaves.
Orange pustules beneath leaves.
In some cultivars, foliage can appear a purple colour.
Leaves ultimately shrivel and fall prematurely.
Plant loses vigour.

Biological treatment

There are no biological treatments for rust fungi. Gardeners should pick off infected leaves wherever possible. You can feed plants with fertiliser to help improve vigour. Avoid ornamental Epilobium if possible- these are more prone to rust infection.

Prevention

General plant hygiene e.g, clearing dead leaves, removing and burning infected material etc. Having good drainage in the soil. Good airflow through and around plants.
