In order to save the plant, it is necessary to transplant it. Before the transplant, remove the rotten parts of the roots.

Disease

Rust

On the surface of the leaves appear red oval pads, which later merge and turn into strips of rusty hue. Most often spreads on the underside of the leaf, less often on leaf petioles or stems. If you do not fight it, then this will lead to the death of the plant.

Important! The cause of this disease is a lack of moisture or its increased evaporation from the surface of the sheet. In order to prevent its appearance, it is necessary to properly water and spray the plant. In the case when the flower is already affected by rust, it must be treated with fugicides.

Gray rot

The disease causes a fungus. The stems and leaves are covered with brown rot spots. Further spots increase and cover large areas of the plant. Also, the leaves may become covered with gray mushroom plaque. The disease is transmitted through soil, water and through the air. Other causes of the disease will be increased humidity, an excess of water in the soil, poor ventilation and damage to the plant.

To prevent the disease, waterlogging should be avoided, euphorbia should be planted in a high-quality and loose substrate. If you notice signs of the disease, it is necessary to treat with fugicides.

Root rot

It is easy to determine that dark depressed spots appear on the stem above the surface of the substrate. If the plant is not treated at the time, then they spread and destroy the stem tissue, from which it breaks and dies. In the damaged areas, mycelium of the gray fungus develops.

The reason lies in the soil. The plant becomes ill due to an overabundance of watering, fertilizing, lack of lighting, high temperature content and too dense soil.

Large spots on the leaves, most often dark, will let you know about their appearance. The reason is waterlogging and hot air. The problem may also be in the soil. To avoid the disease, you need the right care. For treatment, fugicides are used.

Pests

Nematodes

Over time, they become thinner and begin to shine through. Later they dry up and die off. Even later, the plant dies. For prevention, it is enough to keep the plant dry, spraying it.

As for the treatment, only chemicals that are toxic to humans will help here. Therefore, if the plant is damaged by nematodes, it will not be possible to save it.

Spider mite

Small enough, red or light brown. It feeds on young leaves. Signs of infection are white or yellow spots on the leaves. To fight, you can treat the plant with a soap solution. In a more serious form of infection, treat with acaricides.

Mealybug

It affects the roots of the flower. The infected plant stops growing, the leaves turn yellow, dry and die. When infected with an insect, it is necessary to remove the plant from the pot, clean it from the soil and treat the roots with insecticides. Disinfect the pot and plant the plant in new soil.

Aphid
