The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner.
- Fuchsia enthusiasts should avoid ornamental species of Epilobium and eliminate weedy species
- Pick off affected leaves as soon as they are noticed and feed the plants to boost vigour
The fungicides tebuconazole (Provanto Fungus Fighter Concentrate), tebuconazole with trifloxystrobin (Provanto Fungus Fighter Plus, Toprose Fungus Control & Protect), and triticonazole (Fungus Clear Ultra) are approved for the control of rust diseases on ornamental plants, and can be used to control the disease on fuchsias. However, tebuconazole and triticonazole both belong to the triazole group of fungicides. It should be noted that fuchsias are stated to be very sensitive to damage by this type of fungicide and some authorities say that they should not be sprayed.
We suggest spraying a few leaves first and waiting at least three weeks to see if any damage occurs. This wait may mean it is then too late to spray in that season, but will give an indication of whether spraying can be carried out safely in future years.
