Fuchsia rust is caused by a fungus, and appears as pale patches on the upper surface of leaves, with corresponding spore filled orange pustules, on the underside.
The windborn spores may overwinter on Willowherb plants and some forms of fir.

The lower leaves are usually worst affected, these shrivel leaving a straggly lack lustre looking plant.
Remove infected leaves when noticed and destroy any badly affected plants.
