Indian hawthorns (Rhaphiolepis spp.) are compact evergreen shrubs or small trees that are valued in plant hardness Zones 8-11 of the Ministry of Agriculture for their neat shape and clusters of fragrant pink or white flowers that appear in spring. Potentially, this plant can be affected by several diseases, although proper care methods will prevent or minimize the effects of most diseases.
Entomosporous leaf spotting
Entomosporous leaf spot, as a rule, the most common disease of Indian hawthorn, is caused by fungi of the genus Entomosporium. This disease manifests itself on old leaves in the form of small reddish spots, sometimes surrounded by a yellow halo. The spots darken and increase, white masses of spores may form; leaf fall also occurs. Fungal spores spread by spraying water, so avoiding watering from above and pruning branches to improve air circulation can limit the spread of this disease. Good sanitation is also important, including the removal and disposal of infected or fallen leaves and the replacement of the soil cover under the hawthorn with mulch. Where leaf spotting has been very problematic in the past, preventive treatment with chlorothalonil or copper compounds may be justified.
Ognevka
The fire disease caused by the bacterium Erwinia amylovora manifests itself on the branches of hawthorn in the form of shells, from which a bacterial plaque of light brown color is released, which darkens over time. Splashes of water or insects transfer bacteria to flowers or shoots. Affected shoots, leaves, flowers and fruits turn black and die, but may remain on the plant. Pruning infected wood in summer or winter, avoiding watering during hawthorn flowering, as well as avoiding heavy pruning or excessive fertilization, which stimulate new growth of vulnerable plants, will limit the spread and impact of this bacterium.
Phytophthora collarbone and root rot
The Phytophthora soil fungus can cause collar and root rot in Indian hawthorn. This disease usually affects plants only in warm, poorly drained soil. The leaves on infected plants look withered or arid, and dark oozing areas may appear on the bush near the soil line. Good soil drainage and rational use of water are crucial for the prevention of phytophthora.
Powdery mildew
Powdery mildew fungi appear as a white powdery coating on leaves, shoots and sometimes on hawthorn flowers. New growth may look deformed, and infected leaves tend to fall off prematurely. Powdery mildew fungus spreads by the wind and prefers shady conditions and temperatures from 16 to 27 degrees. To avoid or solve problems with powdery mildew, plant Indian hawthorn in full sunlight; plant bushes so as to ensure excellent air circulation; avoid using excessive or fast-acting fertilizers; if necessary, use sulfur to prevent disease or garden oil to fight infection.
Verticillium wilt
Verticillium wilt, caused by the fungus of the same name, affects the vascular system of Indian hawthorn, causing leaf discoloration, wilting and dying, which often begins in separate areas of the plant or on one side. When the bark is peeled off, dark spots appear on the infected wood. Providing Indian hawthorn with the best possible care, including proper watering and fertilization, can promote healthy new growth and bush survival.
