Diseases That Affect Fuchsias
Botrytis
Botrytis is recognisable as a grey mould on the stems and foliage. This is one of the two main types of disease problems you are most likely to encounter when cultivating fuchsias. Botrytis can be prevented and even sometimes cured by allowing your plants a good circulation of fresh air. Another cure is to spray them with a systemic fungicide.
(Available at a majority of Nurseries or Garden Centres).
Plants that are being overwintered will also require good ventilation. This is achieved by opening the windows and doors of the greenhouse during the winter when the weather is reasonably mild and dry.
Rust
This disease is recognisable by the presence of reddish brown ring markings on the upper leaf surface. The underside of the leaf will have what looks like orangey brown spores which are not dissimilar to rust in appearance. The first action to hopefully cure this menacing disease is the removal of the affected leaves and then immediately burn them. The plants are also thoroughly sprayed with an appropriate chemical that is available at any competent Nursery or Garden Centre. Isolate the affected plants and carefully inspect all the others to ensure that rust has not spread to any of them because this disease is very contagious and can cause major problems.
It is always an excellent procedure to quarantine plants for two or three weeks after purchasing them to ensure they are not affected with either of these diseases.
No specific insecticide or fungicide is mentioned because manufacturer’s trade names and their formulae are constantly changing.
To prevent unsightly markings appearing on the petals, do not spray the plants with insecticide, fungicide or even clear water once they are in bloom.
It is most important to follow the manufacturer’s directions very carefully.
Be sure to spray underneath the leaves as well as above.
Thoroughly wash your hands after using any chemicals.
Unfortunately we don’t live in a perfect world, and because of this we are aware that fuchsias, like many other adorable and popular plants, do occasionally attract such things as pests and diseases. At least with modern day fungicides and pesticides it is possible to keep both of these undesirables under manageable control. When administered to affected fuchsia plants as per the manufacturer’s
instructions, they will eradicate the majority of pests and diseases you are ever likely to encounter.
Although not classified as a disease, some varieties of fuchsias produce dull reddish foliage when subjected to uneven temperatures or draughts.
