Phlox diseases: how to treat
Phlox diseases can be both viral and fungal. Moreover, the second type of disease is quite easy to cure. Fighting viruses is much more difficult, so it makes sense to prevent such ailments.
Such diseases are transmitted from a diseased plant to a healthy one through pests such as aphids, ticks, cicada, and roundworm. Unfortunately, viral diseases cannot be cured. Therefore, at the first sign, it is necessary to remove the damaged flowers and burn them away from the site.
Phlox diseases are easier to prevent than to cure
There are several viral diseases that can affect phlox. You can recognize them by the following symptoms:
- Variegatedness. It is characterized by the appearance of light spots on the petals of flowers, as well as the distortion of the shape of the leaves.
- Necrotic spotting. Brown spots with a diameter of 1-3 mm are formed on the foliage. As the disease progresses, the affected areas increase in size.
- Curliness of leaves. The stems of the flower are deformed, and the plant itself is reduced in size. The shape of the leaves changes, moreover, they become covered with black or yellow-green spots.
To prevent the appearance of viral diseases, it is necessary to carry out preventive measures. To do this, always check new plants as well as the soil on the site. Before planting, treat the soil and garden tools with drugs such as Carbation, Nemagon or Chloropicrin.
How to treat phlox from fungal diseases
Such diseases on flowers are not so rare. But they can be quickly cured. Major fungal diseases:
- Rust. Yellow-brown spots are formed on the foliage, which increase in size. Treatment consists of removing the affected areas. In addition, you need to treat the soil and plants with 1% Bordeaux liquid with the addition of ferrous sulfate and copper chloroxide.
- Septoria. It is characterized by the appearance of gray spots with a red border. The disease is treated with Bordeaux liquid.
- Powdery mildew. A pale bloom appears on the leaves and stems of phlox, which gradually grows. The disease is cured with a solution of soda ash, as well as boric acid.
- Wilt. As a rule, the disease affects the crop during flowering. It can be recognized by the sharp wilting of the foliage, while the stem remains healthy. For treatment, dig up the flowers and disinfect the roots, then transplant the bushes to another place.
Curing fungal diseases in phlox is not so difficult. The main thing is to start treating the plant at the first sign. But it is much easier to prevent the disease than to fight it later. Therefore, it makes sense to carry out preventive measures.
