The violet sissy cannot tolerate bright sunlight and reacts to it by the appearance of rounded yellow spots, which later turn brown. Sometimes holes appear in the center of such a burn. This is an extremely dangerous condition for the plant.
First aid in this case is to eliminate the cause of the defeat. The plant should be removed to a place protected from direct sunlight, preferably on the windowsills of a north, northwest or northeast window. If all the windows of the apartment are oriented to the south, the glass must be covered with a mirror film or paper.

If a violet has not been transplanted for a long time, it will definitely react to such a manifestation of inattention. Brown and brown dry spots on the leavesviolets located below are a signal that the soil in the flowerpot has become alkaline. The soil requires immediate replacement.

- Throw away all the old drainage. Sphagnum moss is used as a new filler, which will provide an acidic reaction for the soil.
- The new pot should be one and a half to two times the size of the previous one.

Diseases of violets and their causes
The appearance of spots of various colors and configurations on the surface of the foliage of a flower may be a reaction to diseases, the most common of which are:
- powdery mildew;
- various types of rot;
- fusarium;
- late blight;
- Bronze leaf spot virus.
The main causes of these diseases are:
- Wrong soil. Garden and forest soil is not suitable for Saintpaulias. You should buy a special substrate for violets in the store.
- Lack of phosphorus and potassium feeding with an excess of nitrogen leads to the development of fungal infections.
- Violation of the rules of leaving. High humidity, too low or too high temperature, lack of lighting also lead to the appearance of fungal diseases.
Powdery mildew
This fungal disease affects both leaves and buds of violets. They are covered with white or grayish-whiteplaque that can be easily wiped off. However, the leaves and buds underneath become weakened. This disease gradually takes strength from the flower. The leaves eventually turn brown and fall, and the buds do not bloom.
In this case, all affected areas of the plant must be destroyed, and the diseased flower should be isolated from he althy ones. For small lesions, the leaves are washed with a solution of potassium permanganate at the rate of a quarter gram per liter of water. Five days later, the procedure is repeated.
How to treat violets from powdery mildew with severe damage? There are many special preparations on sale for this purpose. For this, for example, the drug "Topaz" is suitable. It is often used by flower growers when difficulties arise. The drug is used in accordance with the manufacturer's instructions. They also quite effectively cope with powdery mildew "Zircon" for plants, "Epin" or copper sulfate. Processing is carried out according to the instructions for the drug.
Rot
Signs of rot are brown spots on the leaves. At the same time, they lose their elasticity and wither along with the petioles. There are different types of rot. The brown variety usually affects rooted leaves, babies and young rosettes of violets. The stem of the affected plants becomes brown-brown, softens and becomes thinner. Whitish threads of mycelium can be seen on the soil under the flower.
Treatment consists in the complete destruction of all damaged areas of the plant. In order to prevent violet should be treated with fungicides. For this, the above-mentioned "Zircon" for plants is suitable. The soil under the violet is neededprocess with Fitosporin.
Root rot is outwardly manifested by the appearance of pale spots on the leaves and their subsequent wilting. If the plant is removed from the soil, softened brown roots can be seen. The cause of root rot is high soil moisture with its low acidity. You can help the flower by reducing the number of waterings and cultivating the soil with Fitosporin. You can also treat the plant with Topaz. In order to prevent this disease, it is better to plant violets in soil that retains moisture.
Gray rot looks like a white fluffy bloom on the leaves. It appears due to high humidity and improper watering. The disease liquefies the green parts of the plant, which must be completely removed. In this case, the affected parts of the flower should not be allowed to fall on the ground. In order to prevent the appearance of gray rot, you need to monitor the humidity of the air in the room, do not spray the violet, prevent condensation and stagnation of moisture in the pan.
Fusariosis
This disease first rots the roots of the violet, and then the infection spreads higher, to the stems, petioles and lower leaves, which turn brown with watery edges. This disease develops due to low temperatures (below +16 degrees), due to insufficient fertilizing with fertilizers, as well as when the plant is weakened after flowering.
Unfortunately, a violet affected by Fusarium cannot be saved. It must be destroyed along with the soil, and the pot must be treated with fungicides.
To notto allow the appearance of fusarium, the flower must be properly watered, fertilized and treated monthly with Fitosporin.
Light blight
The appearance of brown dry spots on the surfaces of the presented plant may indicate late blight damage. Such formations spread very quickly. The leaves die off, and the rosette withers before our eyes. To combat late blight, all damaged parts of the plant are removed. The side of the outlet that has not been infected is cut off, treated with a fungicide and rooted. The solution should also be applied to all nearby flowers.
Bronze and leaf spot
These diseases are caused by viruses and are accompanied by the appearance of disfigured brown leaves. Flowering stops, the overall development of the plant is completely inhibited. Viral diseases of violets are not treated, so the flower should simply be destroyed.
One of the reasons that provoke such diseases is the colonization of the plant with parasites.
Pest infestation
The cause of the appearance of various spots on the surfaces of a houseplant, their deformation and death, may be affected by various parasitic insects. Most often, violets are attacked by cyclamen mites, nematodes, aphids, mealybugs, thrips and sciarids. These pests can be controlled by using appropriate insecticides.
All diseases of violets occur due to improper care. It is worth showing more attention and care to this whimsical sissy. She is sure to respond with beautiful blooms and a he althy appearance.
