You need to know about the fungus infestation of the medlar
Under certain conditions, it may cause glossy mediators of fungal diseases are affected. You can protect your shrubs by paying attention to proper care. In case of illness, a quick action is required.
The emergence of fungal diseases
Fungus spores prefer to spread in windy and rainy weather. For the growth you need warm temperatures. Such climatic conditions prevail in summer in locations that are not exposed to direct sunlight.
The spores prefer to colonize diseased or weakened plants, because here you will find numerous opportunities to grow. Damage to the bark, leaves or buds provides the spores an ideal breeding ground. Whether a shrub is attacked by a fungal disease also depends on the variety. Older varieties have often developed a defense system against the diseases and are less susceptible than new varieties.
These factors favor a fungal attack:
Frequent fungal attack by apple scab and leaf tan
The apple scab makes the fungus spores a greenish to greyish discoloration of the leaves, which occurs in the form of spots. This fungal disease is spreading rapidly, because the spores are formed asexually. Heavy fungal infection causes the tissue of the leaf cells to die. In rainy and windy weather, the spores spread.
The tan also causes spotty discoloration on the leaves. The fungal attack causes reddish or black spots. This disease does not lead to the death of the leaves. Fall foliage carries a higher risk of infection because the spores feel and settle here.
control measures
Cut off the infected parts of the plant. To prevent spores from spreading, do not discard the remains on the compost. A copper-containing fungicide eliminates possible spore residues on the plants. This remedy is effective for diseases with the tint. Apple scab you fight with a spray solution based on triforin.
Strengthen your loquat with an extract of field horsetail, which you add to the irrigation water. Alternatively, nettle juice or a garlic clove approach is suitable. You can spray the solutions directly onto the infected leaves with a spray bottle. The stinging nettle inhibits the fungal spores in an infestation, while a regular spraying with garlic in the spring has a preventive effect.
