- Good hygiene can help, as do cultural control measures. These include removing affected leaves, twigs or cuttings promptly and destroy them. Where possible, keep leaves dry to prevent dispersal and germination of the spores
- If pruning out affected twigs or branches, disinfect the pruning implement between each cut
There are no fungicides available to amateur gardeners with specific recommendations for the control of Camellia leaf blight. However, the fungicides myclobutanil (Bayer Garden Systhane Fungus Fighter* and other products), tebuconazole (Bayer Garden Multirose Concentrate 2) and triticonazole (Scotts Fungus Clear Ultra) are labelled for the control of a number of other diseases on ornamental plants, and may give some control of Camellia leaf blight.
The following four products contain a combination of both pesticide and fungicide enabling the control of both insect pests and disease: myclobutanil containing cypermethrin (Westland Rose Rescue); tebuconazole containing deltamethrin (Bayer Garden Multirose 2), and triticonazole containing acetamiprid (Scotts Roseclear Ultra and Scotts Roseclear Ultra Gun). When a proprietary product contains an insecticide as well as a fungicide it would be preferable to use an alternative product if pests are not a problem on the plants treated.
*NB: The following products are being withdrawn:
Myclobutanil (Bayer Garden Systhane Fungus Fighter concentrate and Bayer Garden Fungus Fighter Disease Control). These products cannot be sold after the 30th November 2015 and remaining stocks must be used or disposed of before the 30th November 2016.
