No, Bayer Advanced Disease Control for Roses, Flowers and Shrubs Concentrate is not labeled for leaf gall. Sanitation is the best control. Pull off and destroy all infected flowers. Rake up and remove all leaves, flowers and plant debris that have fallen to the ground. Replace the mulch under the plant. This fungus survives in the soil. Spores of the fungus can be wind-borne for up to a mile. Therefore, control is best achieved when controls are applied to other camellia plants in the community. Fungicide sprays recommended for the flowers include mancozeb. Application of soil drenches, such as mancozeb or captan, around the plant every 2 weeks from late December through January may be helpful in reducing the intensity of disease. See Table 1 for examples of products. Apply all chemicals according to directions on the label.
