Pests and diseases of heather and their control

Diseases and their control of Photinia

Heather has strong resistance, so it is less susceptible to diseases. However, if the plants are not managed well or the environment in which they grow is not good, certain diseases will occur, such as gray mold and leaf spot.

Botrytis cinerea

Gray mold is a fungal disease. When the disease occurs, the flowers, stems, leaves and fruits of the plant will show signs of disease. When the disease occurs, the leaves and petioles will appear grayish white and water-soaked. The plant tissue will gradually soften until it rots, and the plant will eventually wither and die.

Prevention and treatment methods

Drug treatment should be carried out and diseased plants should be removed in time to prevent reinfection.

Leaf spot

Leaf spot disease mainly occurs in spring and autumn. The symptoms are small spots on the leaves. As the symptoms continue to spread, the small spots will gradually become larger until large black spots appear.

Prevention and treatment methods

Treat the diseased plants, destroy them, use drugs to control them, and do not spray the plants.
