Lily diseases: treatment
Lilies are popular with gardeners for their beauty and variety. Some varieties are unpretentious in cultivation, others, on the contrary, are very moody and often get sick, which can lead to their death. Therefore, it is important to know the diseases of lilies and start their treatment on time.
Why do lilies get sick? Their types of diseases
How well a plant will take root in certain climatic conditions and what is their predisposition to disease directly depends on the origin. It can be Asian, European, North American, Caucasian.
The main vector of disease in lilies is aphids.
If the climate is not suitable for the plant, then the flowers can grow weak and bloom poorly. They will be sick for a long time, and die in frosts. Such a lily is more quickly affected by fungi and pests. The main types of diseases:
- Fungal diseases: gray, bacterial, root, sclerocial rot, rust, fusarium.
- Viral diseases: mosaic, rosette disease, variegation virus.
Fungal diseases most often occur in densely growing lilies and are treatable. And viral ones, on the contrary, are not cured.
Frozen plants, “sleeping onion” and chlorosis are not considered diseases.
Diseases of garden lilies and their treatment
Fungal diseases, unlike viral diseases, can be treated. Virals can only be fought with preventive measures. Diseases and their treatment:
- Gray rot occurs during rainy weather. It manifests itself as dark spots on the bottom of the leaves. For prophylaxis, the onions are etched in the 0,5% foundation and planted every 3 years.
- Sclerocial rot is manifested by a white bloom on the bulb of the plant. Fight in the same way as with gray mold. Disinfect the soil in place of the diseased flower with fungicides.
- Fusarium – yellow and brown spots on the bulbs. They are treated with a solution of foundationol, soaking for 30 minutes in a solution of 0,2%. 3 weeks before planting, the soil is treated with formalin.
- Root rot – brown spots appear on the roots of the bulbs. The bulbs are treated with foundationol, and the soil is treated with a solution of colloidal sulfur.
- Rust – bulbs, leaves and stems are affected and become covered with transparent spots, which turn yellow over time. Prevention: removing diseased leaves, feeding with potassium and phosphorus.
The carrier of the virus is often aphid, which is fought with a solution of malofos – 0,3% and a solution of ragor 0,2%. For prophylaxis, all infected parts of the plant are removed.
It is necessary to recognize the disease of the lily in the early stages. Try to cure fungal lesions, and if a viral disease is detected, remove all infected plants from the site and burn.
