Rust fungi are characterised by their orange-brown pustules. They can range in severity from infections that can wipe out a crop to purely aesthetic damage. This species in particular targets Fuchsia, Abies and Epilobium spp.
Rust fungi are characterised by their orange-brown pustules which are irregular in shape and size.
The disease is particularly bad when the weather is damp and wet.
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.
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.
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.
